This Kevlar and Ceramic-strengthened compound offers far and away the best price to performance ratio currently available in a high performance street pad. Performing a proper bedding procedure is critical to the performance of this pad but once complete, you can expect truly world class bite, MOT, minimal rotor wear, pad wear, and noise levels. Dust is medium to high. On front engine platforms, the Ultimate is excellent for aggressive street and autocross use in the front calipers. It also works very well in the rear for aggressive street use. Street only.
