Race Marque Systems

The worst possible work that has ever been done on my 540i. Received my s/​c car with lean tune, died at stop signs/​red lights, black smoke out of exhaust, slipping belt snapped and dented my hood, let my car sit for 3 years and flat bottomed my brand new Toyo tires, and finally blew my engine by leaking water into my engine. BEWARE! Osh is a nice con man.

Osh, your response is pure horse $#it. You handled it very poorly, including swearing to me on the phone and initially completely refusing to exchange or give me any kind of refund. It took weeks of listening to excuses on the phone to finally get money back. You are delusional to think you have a «good reputation» a good amount of the stuff that comes up when you Google your shop along with your name is negative. I should have researched you first. What you sold me was I’ll machined and poorly powdercoated junk.

Amazing staff and service… Ash and Adams are super nice and know their stuff… strongly recommend!!!

Took my 08 328i because it wasn’t running at all. From the second i called to when I picked up my car the guys here where amazing! They talked to me every step of the way with what was wrong with my car. Josh did a great job getting my car up and running and ready to hit the road again in no time. Love the fact that I could ask any question and they would answer me in a way that I would understand. would definitely recommend this mechanic shop and for sure I’m going to keep coming for any of my cars needs!

It’s hard to find a mechanic who is not only honest but also quite capable. That’s why we should spread the news when we have discovered such. My car would smoke profusely every time I started it. Another mechanic had misdiagnosed the valve seals as the cause. If I had listened to him I would have spent more than $ 3000 and not solved the problem. Fortunately a friend of mine recommended RMS. Osh found the cause to be the internal oil separator. While he was working on it, I asked him if I should change the valve seals now that the engine was open. He advised me to save my money. This is of utmost importance: during the entire process, while addressing different issues with the car, I always felt I was getting UNBIASED AND ACCURATE understanding of the problems. I felt that he was always doing what is best for the car while saving me from extra expenses. I appreciate this so much. That is why I highly recommend Osh and his team for your car repair and maintenance needs.

Great service! osh, chris, and adam are really solid guys. i came in with my 1970 002 to change out my center bearing support, transmission mounts, and driveshaft coupling. Adam got it done in about 3hrs, chris gave me a great price and osh, adjusted my carbs (no extra charge) and spilled some knowledge about 1600’s and 002’s. I found my go to shop. go here first dont F* up.

These guys are all knowing BMW car nuts. Osh knows BMW’s inside and out. Tex is a really nice guy working the front office. If you have an 80’s or 90’s BMW and want to turbo charge it or do any other ‘go fast goodies’, this is the place. They have many years of R&D, a Dyno room, they make many of their own parts in-​house on CNC machines…
They can retrofit new 5 lug wheels to 4 lug hubs… they have it all figured out.
They are also a good shop for common repairs and upgrades.
Osh is a straight shooter and more then fair. A+

I found RMS by pure chance while I was looking for a Racing shop in the local area on Google. I did not know that they were a BMW Supercharging specialists when I showed up but they were able to come up with creative solutions and excellent custom work for my Mazdspeed 3. The entire crew is very knowledgeable and helpful and I look forward to using them again, even for none BMW applications.

Just met Osh and his great crew today for the first time! I have got to say I was blown away at the level of service and comfort they make you feel. They take a very personal interest in each individual and vehicle. Can’t wait to return for another upgrade!
