Stoptech Radial Mount caliper bracket converts a lug-mount caliper bracket into a radial mount to allow for C42 StopTech radial mount calipers to be installed.
This caliper bracket is the standard bracket that is used on most Stoptech equipped dirt late models and is a "zero-offset" design. In other words, this bracket keeps the caliper in the same lateral position as a lug-mount caliper.
