What Our Customers Say - 100% 5 Star Google Reviews!

"Garage 56 Knows Miatas!"

Garage 56 knows Miatas! I’ve done arrive-and-drive in their immaculate NC as well as trackside support for my own car. The setup is practically IMSA level and the support you get from Steve and his team is just as high end.

"Outstanding Experience"

I had an outstanding experience at Garage 56. He fit me in for a last-minute track alignment. If you have a Miata race car, this is absolutely the place to go—Steve really knows his stuff and treats your car like his own. Highly recommended!

"Extremely Knowledgeable"

Super helpful and extremely responsive to any questions. Buying parts for an engine rebuild he has been super helpful in getting parts on order and making sure I had everything needed. I look forward to working with him in the future!

"Amazing Miatas!"

G56 works on my street NC, my street/track NB, and my track-only NB! If something is broken, he'll fix it. More importantly, he'll get your Miata set up to race (or for an HPDE) or rent you one of his amazing track prepped Miatas!
