We Test Everything We Sell
We don’t just sell parts — we run them. Every product on this site has been tested on our own race cars at events like Gridlife, NASA, and SCCA. If it doesn’t hold up on track, it doesn’t make it to the store.

WHAT OUR CUSTOMERS SAY
Race-Proven. Community Approved.
“KDM built my Veloster N from the ground up for time attack. The attention to detail is unmatched. These guys live and breathe this stuff.”
— Tyler S.“Best shop for N platform cars period. They’ve been racing these cars longer than anyone. Trust them completely with my Elantra N.”
— Mark A.“Ordered parts, got them fast, fitment was perfect. Called with a question and they actually knew what they were talking about. Rare these days.”
