Porsche 928S/993 P80 BBK Shim Set

These shims allow you to use our 993 Brackets with the Porsche Boxter S calipers, which are monoblock and less expensive than the Porsche 928/993 Big Black / Big Red calipers.   Using Boxter S calipers requires some modification of the calipers to use them in this application.

They are sold in pairs.
