Alloy USA slotted & drilled brake rotors improve braking performance right out of the box! If you're looking for extra performance out of your brakes after a lift kit and larger tires have been added to your Jeep Wrangler JK, look no further! This product is slotted & drilled for maximum cooling. Slotted rotors improve brake pad bite & reduce brake fade, both very important factors when larger-than-stock tires are equipped on your vehicle.
