Great service at a great price. I am someone that works on there own cars but I am new to mustangs and wanted an expert to look over my car Josh pointed out things I didn't even know were wrong with my car. Josh knows his stuff. My car has been running great ever since I look forward to working with JS performance in the future

Josh was a great find. He was timely with everything involved and was honest during the diagnosis. I went to Josh for an entire differential build and axle replacement as well as rear brakes. Wonderful experience and will do business again with him in the future. Highly recommended, he knows what he is doingServices: Custom fabrication

I have used JSPerformance for some time now and only have great things to say about them. Hands down, the best service with no BS. They don't play games and always deliver quality. In a world where cheap parts and shoddy workmanship is the norm, these guys don't stand for that. They use the best parts, do the best work and stand behind it! Highly recommend.

Finally someone (Josh) solved my electrical problem. I was getting no results at 2 previous shops. When a friend of a friend recommended JS Performance I thought I would just be “going through the motions” again and still be stuck with my problem. Well, I am writing this because .....problem finally solved! Thanks, Josh?
