Testimonials

I own a BMW specialty shop and we have used Kassel Performance tunes and coding on over 10 BMWs. Never a single issue. Great for S52 / S54 swaps!!

Jake - Wile Motorsport

The best place to buy BMW parts by far. They go above and beyond to help out. Needed some advice on wiring up my swap and they walked me through everything.

Kassel Performance is always super helpful. I have had several issues with my BMW and they have been able to fit me in and get the work done in a timely manner.  They are extremely knowledgeable and reasonably priced.
