Upgrade your fronts? Well you gotta upgrade your rears too! Alcon's set of matching rear 2 piece brake rotor assembles for F8X M2/M3/M4 vehicles give you both the look and performance of motorsports grate brakes, with the convenience of OEM fit and install time. Light weight, and cheaper to replace in the long run, these are no brainier upgrades for those who either track their car or intend to keep it as a daily for years to come. They fit under all wheels w/o any clearance issues, cool faster than stock, and last longer too!
The unique S-Groove cuts in the rotor surface not only look great, but they do a fantastic job keeping brake pad service clear of material and gas buildup. These also feature 48 curved cooling vanes to help extract heat from the rotor at speed maintaining brake feel and keeping fade away.
