These guys are the best!! Extremely fast service, high quality work, and great pricing. I got my ZF8HP transmission rebuilt with an ATS Stage 1 kit here, and engine mounts swapped with fresh ones on my BMW M340i. Will definitely come back for any upgrades/repairs on my BMW, they are the experts!! read more

Just picked up my 2025 Genesis 3.3t Performance Advanced this afternoon and was completely blown away on how great it looked after after they installed my Adro Carbon Fiber Rear Spoiler. From the moment I walked in, I spoke with Jeff & Jake Detail Clinic and after speaking at length with them I immediately felt comfortable and incredibly impressed so much so I was sold on handing my vehicle into their care. Both Jeff and Jake were completely transparent in walking me through the process from start to finish including promptly replying to various questions I had before, during and after the Installation. Do not think twice, do not even consider going anywhere else for your mod needs! I am a customer for life and have already and will continue to sing the highest praise I can get to my friends!!!! Cheers guys and massive thanks!!!! Jeff read more

I don't trust Toyota dealerships with my Supra because most mechanics there don't really know how to work on a BMW engine (they often need to fly in "Supra techs"), so I found Stryker Performance through Google. Since then, I've gotten aero kits and mods installed at their shop and they've done a fantastic job every time. Their pricing is also really fair. Sam, Jake, and the rest of the team are clearly passionate about what they do and are very knowledgeable about BMWs (and other makes). They put a lot of care into servicing people's cars. I wholeheartedly recommend them for your maintenance and modification needs. (If you're looking to add more power... look nowhere else) read more

Took my F80 M3 in for an oil change and lowering springs. They did a same day turn around with upfront pricing and did the work flawlessly. They also threw in a full vehicle inspection and had another employee help me out with wheels for the future. I know where I will be taking my car for all its future service and upgrades. Thanks! read more

This is my go to spot for general repairs on my BMW. They are honest and reliable. Prices are competitive

If I could I would give them a 10 star review, bs aside. They are one of the best shops in town. I appreciate their honesty and transparency. I came with my e70 X5 M that was leaking oil and coolant and couldn't figure from where. Was also rough in the shifting with at times getting some warnings on cluster and idrive. I dropped the car at night, they started working on it and ran some pressure test on the coolant lines. Found that the engine block cover was faulty and was leaking from there. This is a 10 hour job. They were able to sort out bmw genuine updated parts. They also found that the oil leak was coming from a faulty transfer case motor, got that replaced with oem bmw parts. Before they started to work on it, I had several conversations with Preston explaining the process and how they found the problems and in addition the options I had and which option they recommended. They left it up to me to decide on the following steps. I of course decided to go with OEM parts and and getting all done at once to make it more cost efficient, rather than coming back and perform more work. I visited their facility to see the car and the problem at hand. While there, I spoke to Sam, Jake and Nick and of course Preston. The explained again the route they were going to take to tackle the fix. Which by the way, these group of guys are very knowledgeable and on top of that very cool people to talk to. I truly recommend this facility and most important I recommend these group of individuals. They are genuine. read more

First time coming to them with a slight oil smell coming from the engine bay. They knew right away with the inherent issue of the 28 liter engine where it was coming from.

One of my twin turbos self destructed while driving. I ordered new upgraded ones from ECS Tuning, but they took 3 months on backorder to come in. So, in the meantime, I had a chance to call every BMW Repair shop I could find to install them. It ended up boiling down to 3 in my North Orange County market. I also needed my oil pan gasket replaced as well. This is usually an overlapping repair when doing turbos. But the shops wouldn't do it and wanted the full $900 charge to put in a $25 gasket. Until I found Stryker. They not only charged me a little less for my 2 turbos than the other shops but also only charged me a 1/4 of other shops' fees to install the pan gasket. I also needed a new High Pressure Fuel Pump, and they had two good used ones that they offered to install at half the cost of a new one installed off some engine swaps they did recently. Picked up the car today and it feels just like it did when I bought it new 10 years ago. I highly recommend this crew as they are upfront and not looking to get rich off of you. My car was also done a day ahead of schedule. Under Promised and Iver Delivered! Go see Stryker Performance for all of your BMW needs. read more
