They Do the Job!

I threw these on my 2021 charger after the stock ones started feeling meh. First off, they look good behind my wheels. Second, they work flawlessly. I can actually feel the difference, especially on fast stops.

Excellent Rotors!!!

Absolutely love the look of drilled and slotted rotors, and the R1 Concepts front and rear set did not disappoint!!! They arrived surprisingly quick. Installation was a breeze. Will need to log a few more miles for the zinc coating to wear off the surface, especially on the rear, but they look wonderful!
