Roadster Tuner - Ontario, California

Link C

Came to the roadster tuner to get my front and rear sways installed on my 2021 ND miata,which Is no easy job if you know about this car. As normal I'm always skeptic when I go to mechanics because there can be some shady ones that'll try to charge you an arm and a leg for something you don't need. So as I pulled up I see he has his own s2000 and other gems, has tons of experience with Hondas and mazda. You could tell by his work area that he not only knows how to work on cars, he is a car enthusiasts himself and you can feel that vibe when you talk to him. Not many other mechanics will let you sit with them and chat while they work on your car, even showed me some of his beloved vehicles that were covered. He was proud of his work and even showed me his tool setup Definitely will be back and will bring my friends. If your thinking of a place to take your car to get any kind of mod save your time and take it HERE!

Recently had the pleasure of having Erik, THE Roadster Tuner, work on my NB1 Miata. Started with a brief call to describe the problem and right away he knew what I was talking about. He was able to quickly source the parts that were needed, we arranged for a time and I dropped off my car.

Throughout the service, Erik was communicative, and sharing videos/photos as the work progressed. He is very meticulous in his work and you can definitely tell he has a lot of experience with Mazda Miatas, he has been working on them for 15 years after all. After picking up my car he told me a few things that he would advise I do to the car to make it nearly perfect.

If you have a Miata and need a thorough, knowledgeable, and meticulous person to work on it, don’t hesitate to contact Erik at Roadster Tuner! Just a side note: he is located in Riverside, not Ontario.

Thanks a lot Erik!

I contacted Erik based on location and I am very thankful I found him. I flew into Socal to buy an NC1 Miata. He was able to schedule me for a same-day clutch replacement and also helped trouble shoot other issues so I could make the 7hr trip back home. He is a Miata guru that knows thoroughly how to fix and maintain them.

Erik is very much active in his services. Never I have I met such a precise specialist like him. Was very insightful and knowledgeable on all aspects of my lowering springs installation. It’s like he never touched the car but put in all the necessary work needed. Please don’t hesitate to give him a call! Got a mechanic for life!

I was in need of a clutch replacement and I needed it done by someone who specializes in roadsters. If you're looking for someone who knows what he's doing then look no further. 2 weeks later no problems at all. He's also incredibly knowledgeable about roadsters and taught me things I had no idea about my own vehicle. I would definitely call him up to set an appointment and get the actual location since the address from fremont is outdated.will definitely be goin back for any other major jobs I'm not willing to do my self.

I had took my 2020 mercedez c class coupe to get a c43
amg diffuser installed on it. I picked my car up, then realized he didn't put a part on. I contacted him and he said he would have to charge me 260 which is almost the price for a full install. It didnt make sense why he would charge, if he DID NOT put the piece on as he was told. I also had noticed that he scraped the diffuser part as well!!! I texted him and he didnt respond to anything. I then called a body shop to fix it for me and they did it within an hour for ONLY $55, while he was telling me that it would take him a whole day and $260. HE DOESNT KNOW WHAT HE IS DOING AND VERY UNPROFFESIONAL. DO NOT take your MERCEDEZ here!!
