STR40/44-44/32

The StopTech ACS.A3H.11R4 is likely a right replacement trophy caliper, part of a StopTech Trophy Big Brake Kit. These kits are described as the ultimate street braking system, featuring naturally anodized lightweight components adapted from their racing program. They utilize STR calipers, AeroRotors®, and AeroHats® (as found in Trophy Race BBKs) but incorporate silicone dust boots for extended service intervals and anti-rattle rotor mounting hardware for quieter street operation. The kits also include StopTech® Street Performance brake pads for high-performance street and occasional track use, and StopTech Stainless Steel Lines. Any StopTech BBK can be ordered as a Trophy Sport Kit.
