SR-11 Series: Built for Full Race Calipers

This SR-11 Series racing brake pad is a medium-friction compound suited to high-ABS street-based race cars or the front and rear of full race cars running bias controls, built specifically to the 18mm thickness spec for Alcon TA6/CAR89/CAR11 and compatible AP Racing CP3558 and CP9660 calipers. Because it's sized to these exact full-race caliper families, it's a precision fit rather than a universal pad trimmed to approximate size. Getting the thickness spec right matters for proper piston travel and pedal feel in these caliper designs. It's a distinction worth understanding before you buy, not after.

A Pad Built for a Specific Caliper Family, Not a Factory System

This pad is intended for cars already running one of these specific full-race caliper setups rather than a factory braking system, so it's not a direct swap for a stock caliper. If your car isn't already running an Alcon or compatible AP Racing caliper, this isn't the right starting point regardless of how appealing the SR-11 compound sounds. For cars that are already built around this hardware, though, it's a precision match rather than an approximation. For a component this critical, that level of specificity is exactly what you want to see.
