    Great experience start to finish with Young and Johnathan. They really know their stuff with K series and are true enthusiasts themselves. You'll be in good hands with them.

    Car in the shop! Worked on by Young himself

    Always a pleasure bringing the car here. I can proudly say Autotuned is one of the few shops I'm willing to drive an hour plus out of my way for.

    They do general maintenance here as well! Awesome fast service for my Tesla. Instead of going elsewhere and waiting and waiting and waiting. Did quick tire rotations and cabin filter change. Made sure my tires were filled and wheels were aligned. Super friendly service. Highly recommend.

    If you have a 86/BRZ platform, this is the place to go. Young and his team is super friendly, informative and professional. The customer service here is exceptional. I got the new oil pan baffle, oil pick up, track spec louvers installed and timing chain cover resealed. Car was at the shop for two days. During the process, Eric is very communicative by sending me pictures, updates and answering my questions. They will not only complete your requested tasks perfectly, but also go beyond by checking other parts of the car to make sure everything works properly. Young and the other two team members are willing to take extra time answering my questions patiently and showing me the components of the car that I need to pay attention for. And if you are concerning about certain things after the tasks have been done, young is also willing to check the car for you again. Five star for Auto Tuned for sure!

    Took my 2005 Dodge Ram Daytona in for a face lift. I removed the original fin and had a Tonneau bed cover installed then let Young do the rest. He pulled the old faded decal off. He showed me how uneven the original decals were put on and it really showed with the new bed cover. We discussed and I went with his suggestion to start the stripe from the fog light and bring it all the way back and up and on to the cover. I love the new look! Dropped it off on a Friday about 1 and was ready the next day at 1. Fair, prompt and great communication everything you want in a business.

    Came back with 12 wheels and 12 tires that needed to be mounted asap due to an upcoming track event! Young and Melody stayed late to help get me sorted out! ( sorry guys for making you stay late haha)

    I happened to come across Autotuned while reading some forums and I'm glad I did. Although I live a bit far out from Monrovia, it was always worth the drive to leave my car in the hands of Young. His knowledge of the 86 platform is unmatched and I learned (and am still learning) so much about this car. I've gotten my suspension issues fixed and gained more power with Young's recommendation for the Jackson Racing supercharger. Not only that, Young, Melody, and Vic have always been helpful and made me feel welcome whenever I arrived at the shop. Will only be coming here for all my future modifications and maintenance. Thank you Autotuned

    See all

    RTMotorworks - Alignment done for this brand new Juniper

    RTMotorworks

    I was in need of getting new brake pads and rotors for my 2020 BMW X5. Was getting quotes from a…read morecouple of other places but getting the quote from RTMotorworks was thorough. I was hoping I just needed brake pads for the front and hopefully not all 4 wheels at the time. They were very responsive and the quote was comparable to other places, if not better. Decided to take it in on a Friday in the morning. Checked my wheels and told me I just needed the front brake pads and rotors replaced. The back was still good. Sigh of relief somewhat. They were able to get the pads and rotors replaced for little under 3 hours. Time went by and they were updating me during the whole time. Great service and team here. Will definitely bring my car back in to get other services done. No issues whatsoever with the new pads and rotors.

    PROBLEM: ALIGNMENT ISSUES, CUSTOMER SERVICE, ACCOUNTABILITY…read more When I first tried to leave a review, my account was somehow blocked from posting specifically for RTM, while I could still review other businesses. I contacted Yelp, and by coincidence, the representative I spoke with was also RTM's Yelp rep. He said it was strange that I couldn't post only for RTM. After I explained my situation, he advised me not to leave a review and instead take the matter to small claims court--which I did. During the hearing, the judge seemed to understand my side, but the ruling ultimately favored RTM. Despite being advised not to post this, I'm sharing my experience here because the situation still doesn't sit right with me--especially given Yelp's controversial review practices. On 10/1/25, my rear right adjustable control arm snapped. My car has aftermarket wheels, tires, and suspension components, so a precise alignment is critical to ensure proper fitment without rubbing the fender. I initially went to TM Auto (located across from RTM) for the control arm replacement. After installation, TM took my car to RTM for alignment. I specifically asked them to match the rear right alignment to the rear left, which was set at -2.8 degrees. When I went to pick up my car, I immediately noticed the rear right wheel did not match the rear left. The camber was visibly off. I pointed this out to the technician, but he insisted the alignment was correct and that there were no machine or human errors. After repeated requests, they put the car back on the rack, but instead of rechecking, two additional technicians came out and dismissed my concerns with questionable explanations: "Toyota made the fenders uneven." "Your control arm is made in Taiwan/China--what do you expect?" Despite putting the car back on the rack, they never rechecked the alignment. They simply removed the car and stood by their original claim. With no resolution, I had no choice but to drive the car home. Because the alignment was incorrect, my tires rubbed against the fender the entire way. The next day, I found heat damage, paint cracking, and visible wear on the fender. I came back the next day to talk to Richard (the owner) hoping he would recheck everything, but it was apparent he was "too busy"--despite clearly having time to talk with other customers and then continue working on another car, while ignoring me. I waited outside RTM for over an hour trying to speak with him. When the TM Auto manager asked if he had seen the damage, his response was, "Yeah, so what?"--with no concern at all. After is when I left, and was forced to go to another shop to realign--more driving, more damage done. I used a camber gauge and measured -2.8 degrees on the rear left and -2.0 degrees on the rear right. To confirm, I took the car to my trusted shop, Chewerks in La Habra, where they verified the rear right camber was indeed -2.0 degrees and did not match the left side. Their measurements matched mine exactly. Because RTM refused to recheck or correct their work, this improper alignment caused damage to my car. The rear left side tucks properly, while the rear right sticks out about half an inch, which led directly to the rubbing and damage. I had clear documentation and evidence, but the court still ruled in RTM's favor. I chose not to appeal to avoid spending more time on the matter. A nearby body shop, Cenco Auto Body, quoted over $1,800 to repair the fender (with another shop giving a similar estimate), confirming the extent of the damage. What could have been a simple recheck turned into a costly mistake. Despite everything, RTM did not offer any compensation or attempt to make things right. Seeing RTM's highly rated Yelp profile made their response even more surprising. They're quick to take your money with a smile when things go well, but when issues arise--as in my case--they deny responsibility and make no effort to make things right (In my case, they didn't take money directly, but a receipt was given to TM Auto, and I had to pay TM Auto--which is the same as paying RTM directly). TM Auto went as far as offering RTM to help cover the repair costs, but RTM still refused. TM Auto didn't have to step in for someone else's mistake, yet they still tried--that says everything. Richard (the owner) had my contact information through the small claims process, yet he never made any effort to contact me--even before we went to assigned court date. After what happened, I'm relieved I didn't bring my other cars first--especially since those cars are of higher value. It seems RTM has many satisfied customers, along with a smaller number of unhappy ones. Hopefully, you don't end up in the latter group like me. FWIW: Following the incident, I contacted Hunter to verify when RTM's rack was last calibrated. Abel (rep) advised that its calibration was set to expire later that month. This raises the possibility that their rack may have been out of calibration.

They installed an Eibach Pro-Truck Lift Stage 2, paired it with ELEVATE upper control arms, and mounted Method MR703 wheels with Toyo Open Country AT3 tires--the truck turned out absolutely perfect. Ken also tracked down the Heritage Wheel caps that I wanted. The team was knowledgeable, professional, and clearly knows their stuff when it comes to off-road and suspension setups. Fitment, alignment, and overall attention to detail were spot on. The LC250 rides smooth, handles better than stock, and looks incredible. Communication was clear throughout the process, timelines were met, and the quality of work speaks for itself. If you're looking for a shop you can trust with your build--whether it's suspension, wheels, tires, or general service--88 Rotors is the place to go. I'll definitely be back for future upgrades.
