The K5985 Evolution Drilled Slotted Ceramic brake system is a must-have for any serious automotive enthusiast. As my tests showed, these brakes are highly effective at reducing stopping distance and preventing fade even under extreme conditions .The drilled and slotted design also adds a touch of style to my ride. the only downside is they can be a bit noisy when first installed. Overall, highly recommended for anyone who wants the best in brake performance..
