Took my Mk4 Supra here after purchasing it to get it checked out by a shop that specialize in JDM cars. Linh did a thorough inspection and gave me straightforward recommendations on what maintenance needed attention. He spotted oil leaks from the valve cover gasket and got it fixed the following week. His guy even went the extra mile to cleaned up my motor. The whole process was smooth, no pressure, just honest work. A solid JDM shop that knows what they're doing. He's going to be my go-to mechanic for any work moving forward. Plus, fair pricing too! read more

JER Development - Auto Repair Near Me - Westminster, California

They broke the rear main seal in my transmission, causing a massive oil leak, resulting in ringland failure in my WRX

First time here, was referred to by a fellow Z31 owner. I'm glad to have met the owner and his team. Linh was able to give me multiple options, articulated clearly before and after the inspections and a fair price. Linh explained things very thoroughly and was pleasant to communicate with. His crew was able to detect flaws, unfortunately made my previous repairs from other shops. All in all, I was satisfied with the work done today on my 1987 Nissan 300ZX. read more

I've been using JER for a few months for regular maintenance and also performance upgrades. Mr. Lin without a doubt is a master at his craft and I recommend any and everyone to his shop. I trust his expertise when it comes to my 300zx. Stop by you won't be disappointed. read more

Linh is very helpful and kind. Helped me get my mustang 21 springs on and got it done in a few hours. Fair pricing as well. Car collection that he has is also massive. Can tell he cares about his community and passionate for all makes and models. read more

As a car owner, it's very frustrating to deal with car issues. Unluckily for me, my check engine light on my car turned on. Learning from my past, I immediately tried to turn my gas cap tighter hoping that would remedy the issue. It didn't. So sadly, I went to my local pep boys just so they could pull the code - P0730. If you google it, it's basically a code saying your transmission is all messed up. Of course, being a girl means that I have a giant target on my back when it comes to cars saying "RIP ME OFF PLEASE!!!". Linh didn't do that at all. I took my car here and he tested it and drove it around to see what the issue was. My transmission fluid was dirty so he recommended we change it and see what happens with the car. He did tell me that there would only be a 1% chance that was the actual issue, but I was banking hard on that 1%. He told me what to watch out for to see if there was an actual issue with the transmission. He was very friendly and had a lot of information and knowledge about my car. Well, I left and Linh was right. My car's transmission was slowly slipping (I witnessed it myself via the jumping RPM, just as Linh told me) and it would have to be rebuilt. Linh quoted me a price and told me it would take at least a week to fix. A week without a car....who can live a week without a car in SoCal?! Linh did his best and he got my car back to me within five days. The price he gave me was much lower than a dealership and he still offered a warranty of 12 months/12,000 miles attached to it. Overall, my car feels basically like I'm driving a brand new car. His honesty and decent pricing is the reason that I'll keep coming back to him. read more

Fair pricing, honest to goodness truth and step by step recommendations on what you can do to get your car running like new! They do everything from your run of the mill oil change to custom fabrication of turbos and anything and everything in between. If there's something you want done to your car, rest assured, this place is the place to go to. You can tell he's experienced by the vast quantity of high performance sports cars in the shop and the frankenstein machines he's built, ie. a Mini truck running a K series motor! I tell all my friends to come here and everyone's been completely satisfied with the work and friendliness of Linh and his workers. My friend's SC died on her and she brought it elsewhere only to be told they couldn't identify the problem. I told her to bring it to JER and in 2 days he had it up and running smoothly again. She told me he's a miracle worker and I happen to agree. read more

Very happy to have found this place through Yelp. I was having issues with my suspension (32 adjustable coilovers, k-sport) on my 2007 acural tl-s. It was originally installed by one of James the fender defender guys who is associated with Outcast Garage... For months almost half a year I've been trying to figure out why the hell my ride was so bouncy when I bought BRAND NEW coilovers from Outcast... Thinking back, my boyfriend had told me when he took it to get the suspension originally installed (Outcast referral), the guy who was working on my car was rushing and got frustrated because in order to get to the back dampening system, the entire back seat had to be removed which I guess caused him to rush while doing the install. But, like anyone... If I'm a paying customer, I would hope the job is done correctly which was NOT. Anyhow, I swore to myself that I would NEVER take it back to any of Outcast Garage referral or associates. Hence, I looked on Yelp and found JER. Took my car here for a suspension diagnostic, told the owner Linh everything I was experiencing and he started educating me about what he thought it may be etc. He had to leave, so he told one of his guys what to do.. when I came back, I test drove my car and wasn't satisfied because the guy told me he did his bes, but thought it may have been defective shocks, but luckily Linh had came back, so I SPECIFICALLY REQUESTED for him to look into it one more time before I had to seek another option (completely buying a new set/different coilovers). Reason for doing so is because of his knowledge/experience. Linh was very accommodating and went above and beyond to correct the issue himself. He personally took over and put in the time to restart and reset the whole suspension install. He found that the spring rate (preloads) were off as well as the dampening. Even though the work for this took the whole day, Linh gave me a great price because he understood my frustration and I could tell that he really genuinely cared about customer satisfaction. Overall definitely a great experience coming here and highly recommended. Best to call ahead of time to set an appointment or drop off the car and get a ride to run errands or eat because they can get pretty busy (as expected for great service). Will definitely be recommending other friends to come here. read more

Linh and his crew is very good with his cars. Every time i have an issue with my car i bring it to him and he knows whats the problem right away. I super recommend this place. Also forgot to mention that they're super friendly too! read more

I took my car here about a year ago and this guy kept my car hostage for 10 months. I got my motor fully built and re did the head and still having issues with timing and have spent thousandths of dollars in between because of the crap job this place did on re assembling my engine and I was over charged and taken advantage of. Maybe this shop does somewhat well with stock vehicles or modified JDM but they sure of hell cannot work on modified boosted mustangs. Do not take modified mustangs here he doesn't know what he's doing or he might just be a greedy person and rip you off. read more

Terrible service, after taking my car here spending thousands of dollars I come to find out all the work was done wrong and now having to pay a trusted mechanic to fix everything this place did wrong. Please beware and go to a better shop you dont want to be like me and still be without a car 5 months later.... read more

Took my genesis coupe to get the alternator switched out and I figured since I was here just get a tune up as well. Billy had some great customer service along with showing me all the cool cars he was working on. I had some problems the next day with the check engine light but I figured it had to do with my car dying and my electrical with the problems I had with the battery the day before. I took my car back the next day and they checked it out again free of charge and made it back to good condition! Definitely come back here again for any car troubles. read more

I have finally found the shop to collaborate with on a custom JDM build. The owner absolutely loves what he does and has been doing custom builds and servicing vehicles for almost 30 years. Within 5 minutes of my visit I was getting a tour of the amazing projects he has in the shop. He knew the details of everything I asked about on customer builds. His passion to do things right is what sold me, you can see how genuinely he feels about his work. read more

I've always came here for general car stuff and for projects, never has there been a bad moment with the owner, he's funny, comes out to greet you and chat it out and they give you the best of services and the quality of their work shows and it proceeds them very well. I highly recommend this Shop for anything, they know their cars very well and know the motor sports world well.. read more

Been here twice for, first new clutch installation, second lift kits installation, for my Subaru WRX. Linh and staff are awesome. They are friendly, informative, responsive, and always keep me update (they often stay opened late to get the jobs done, so that quite respectful). Shop tour always amazed me since they often have new crazy builds at the shop. Bottom line, I'll bring my car here again, as well as I would recommend others to bring theirs to JER. read more

Went to multiple shops to get a quote on adjusting my CF hood for my 350z. Lin gave me the cheapest price and adjusted it without damage. Came back to remove a stripped and damaged endlinks and replaced bushings for a fine price. Would definitely recommend this shop for everything from A to Z. They have amazing project cars in there! read more

My uncle recommended me this place because I needed a new mechanic in the area, coming from San Diego. I have to say I'm always very pleased with my service here. Linh is very honest and hardworking, always giving me the best deals and prices. I never even have to question if he's giving me good deals or not. He charges very modestly for labor, and he'll order any parts you can. Be sure to call in, because this shop does get pretty busy. If he doesn't pick up, it's best to leave a voicemail, he'll get back to you when he can. I've come in for headlight changes, and all of my brakes and rotors that needed changing. read more

I've been going to JER for over half a year now and will continue to support JER because of their reasonable pricing but more importantly for the owner Linh's honesty and impeccable quality of work. For now, JER is my go to place for standard maintenance, but will definitely be a place for my future project cars. I highly recommend this place and if you're a Lyoness member like me, JER is a participating loyalty merchant of the program which means, with every service, you can also earn cash back. read more

I used to come to JER when they were in there Garden Grove Blvd location and was bummed when it closed down. But when i heard they relocated I came in to get some work done on my S2000. Linh does excellent work and is an all around cool guy. Prices were very reasonable. I will definitely come back. read more

I've been going here for years! The reason why my truck has lasted so long is because of Linh. I go here for the 5 star service and Linh's massive knowledge of anything automobile related. I used to drive 25 miles just to get a freaking oil change here. Why? Because I can TRUST Linh. He will let you know what's up with your vehicle and won't try to pressure you with anything. I can call him and get advice on my vehicle and he's always happy to assist. One time I dropped my car off at his shop for it to get worked on and he offered to take me to the rental car place for me. He not only drove me to the rental car place but also drove me in a freaking FERRARI. I felt like I was in rap video when I got dropped off at Enterprise. Don't believe me? Go check out JER and see for yourself. read more

My husband's car was overheating repeatedly, and I had my doubts when Hien diagnosed the problem to be the same as what the other shops had said. I don't know what he did differently, but with Hien's help, we haven't had any more problems, and it's been close to a year. It's a no frills shop, but what could be more important in a mechanic than honesty and reliability, especially for a person like me who's clueless about cars? Now we only take our cars to them. Thanks, Linh and Hien. My husband and I are lifers. read more

Linh and his brother Hien are probably the coolest car fanatics I know around and they do a great job along with all his workers. Once I bought my Evo I knew what kind of shop I wanted to go to and they treat me as if I'm family. All my car and bike projects will go through them from now on. I've literally fixed my Evo from decent condition into a head turner thanks to Linh and his brother read more

When I first came here by recommendation I was really surprised to see how much Lihn was into cars, he's a genius, he has so much experience from swaps to turbo setups, I would greatly recommend him for any project. I recently dynoed my Z on hid dyno and loved the experience. I think he's doing a 49.95 five run special which is real good price compared to other shops. read more

Fantastic shop! Every time I visit I'm impressed by the service and the commitment to make sure the customer is satisfied. Thank you

Excellent shop Linh did a great job installing my exhaust system will be back for more work.

Linh has been taking care of my car for nearly a decade. I trust him completely. He is always extremely fair and extremely honest. He does an amazing job every time. He goes above and beyond that of any mechanic I've ever met. He takes care of my car like it was his own. I trust him 100% without hesitation. I wouldn't take my car to anyone else. He is thorough and takes the time to figure out problems rather than guessing, even when they are extremely difficult, which is often the case with me car. I have referred all my family and friends to him and he gives them the same amazing service. He backs his work 100% and doesn't play game, try to take advantage, or ever say things need to be fixed when they don't. His prices are more than fair. You could never find a better mechanic than Linh! read more

I was referred to JER by my coworker. Really happy I went there to get my Camry fixed. The car had a bad alternator and really rough idle. Linh set me up with a rebuilt alternator and diagnosed the rough idle and stalling to a dirty throttle body. With a new alternator and clean throttle body, my car is now running as smooth as ever. Great shop!! Will definitely be taking my cars here from now on. read more

I love this place. They charge a fair price, provide excellent work, and gave me honest advice. I have been to cheaper places in the past and have been burned (not getting my oil filter replaced when I paid for my oil change). Also, my car had some engine issues. They were the one that fixed the issue after I went to two other shops! On top of that, they have been in business for a long time and they are very knowledgeable. I highly recommend giving them a call and check them out yourself! As you can tell, I am a huge fan of this place. read more

This is my first review on Yelp and it goes to the guys of JER! Just to keep it short but I would highly recommend going here for much of your car needs. Linh and Hien are cool and are able to answer all your questions; fast next day appointment and reasonably priced service! I had sport springs installed on my Elantra '13 one day, then a weld-on muffler later on. Love the results of all my mods so far, and I will probably come back here in the future once I've saved up for a set of large rims+wheels. :) read more

Came here to get my d2r headlight replaced for my Infinit G35. Other places ask for 120$+ just to change the bulb, luckily Jer Development quoted less than that. Also, my car seems to be missing some fender push retainer, Linh gladly took some of his fender push retainer from his GTR and installed on mine, haha now I can claim that my car has parts from GTR. Definitely will take my car back here for future auto repair. Linh seems to have great enthusiastic about car. read more

Came here for a turbo install. He seemed very knowledgeable, but ended up costing me a fortune. They stripped my oil drain when they tapped into my oil pan I'm no expert, but even I know not to tap into an oil pan below the oil line. They forced the screw into the oil drain and when I unscrewed the bolt it broke off. I then removed the oil pan and found all the metal shavings everywhere. Surprisingly, my oil pump is still working, but my turbo starved because the oil line was clogged. He also did not put any effort into finding good AN fittings for water lines. He just hooked up the stainless steel braided hoses directly into banjo bolts. Since the hose sit right next to the exhaust housing both hoses cracked and coolant spilled everywhere. That could've cost me my engine because the car started overheating. I asked him why did he install the water hoses that way and he said he couldn't find any AN fittings. That's funny because I had to find them myself and it wasn't difficult. All it took was one call to Earls performance plumbing. I will never come here again nor recommend this place. I ended up JER Development paying over $5K when everything was all said and done and I still had to pay extra even after such as new oil pan, new water lines, AN fittings, new turbo heat wrap, new Gatrett Turbo... That's all I can think of right now. Hope this helps. read more

I take all my cars to Dr. Linh. I call him doctor because he literally brought my 300ZX back to life. It was sitting in my garage for 7 years. I finally had some time and towed it into JER a few weeks ago. It's fixed now and now I drive it everyday to work! I forgot how much I loved this car. His prices are great, but most importantly, he knows so much about EVERY car....from Hondas to Lambos. Tell him that Andy sent you...... read more

Linh is the man. Brought my 350z here because the motor was burning oil. To be honest I was debating on getting my motor replaced either at Corner 3 garage or JER, and Lihn pretty much won the bid. Don't get me wrong Corner 3 is cool, but this is about JER. The motor swap same vq35de he did is still running strong. He now does all my oil changes to now, I know I should do it myself but it is Lihn how could you not take your car there. He has also done some body work. He has a body shop now actually he repaint the left side of my car and install a v2 bumper and painted it as well. Good prices, check him out. read more

Linh, Owner of JER, is a well experienced mechanic/fabricator. His skills and knowledge about automotive is so vast that you can literally get anything on wheels fixed here. Given the problem, he will walk you through the steps to fix it/cost. The location and size of the shop is definitely hard to spot, but with the amount of experience Linh has, the shop has been pushing out top quality cars landing in the media. read more

Linh is extremely knowledgeable. His crew are excellent. I appreciate their service. Any time I had an issue with my vehicle Linh, diagnosis the problem, explains the problem in debth so well. I've been servicing my car here for four years now and tons miles on it and my car runs fantastic. Thank you guys! I definitely recommend this auto shop. read more

I have a 1989 BMW and have had Linh and his crew wrench on it. Linh is an interesting guy, and he is in the right business since he likes cars especially performance cars. On the bimmer, I had a timing belt change, rear transmission seal change, central carrier bearing change. I also brought my Audi and had the transmission fluid change, transmission filter changed, outer tie-end rods, and shocks replaced. The price is reasonable and is fair. I give JER five stars for their heart and effort because they try to do the best for their customers and they are very flexible. read more

Knows his stuff, but does not really seem to work on your car since he has his other employees doing it. Had my brakes done there and a few days later my car started to make that nasty sound when you back up. Then he was telling me that my transmission was going out which it wasn't since the engine is really strong because I took it to Cobb tuning which is a place where they are really completely honest. I wouldn't recommend anyone to come to this shop. Over charges you and doesn't complete the work. read more
