Customer Comments

I brought in my Mazda RX7 GS and you guys transformed it! Logan did great clutch work and fixed the front suspension system. Logan knows his stuff. Have some more work in mind. 140 horses out of a 12A maybe? Looking forward to it. Thanks!

My 88 has always had an overheating problem in slow moving traffic. You found the problem and fixed it right away. Now my temp runs dead center. Wish I had done this a long time ago.

Mazda Enthusiast, Marlin W. | 1988 Mazda RX-7 | Gen 2

My turbo never seemed to work right. Logan made some adjustments and rewired and resoldered many of the older wires that had been done before I got the car. I can't believe the diff. Thanks a million!

Mazda Enthusiast, James W. | 1992 Mazda RX-7 | Gen 3

I have an older RX-7 which always had a sloppy steering. I was really worried that it couldn't be fixed without costing me a lot of money. Well you fixed it and for a whole lot less than another shop. Will be back.
