The K2748 Evolution Drilled Slotted Ceramic kit is a must-have for anyone LOOKING for optimal braking performance. According to my experience it drastically improved my automotive braking ability and reduced stopping distance. The drilled and slotted design keeps the brakes cooler during intense driving conditions, and the ceramic material provides a consistent, quiet, and dust-free stop .The only potential con is that this improvement comes with a higher price tag, but it's undoubtedly worth it for the added safety and driving experience..
