Girodisc Rear Caliper Rebuild Kit Porsche 991 S/4S/GTS
$56.00
PORSCHE REAR CALIPER REBUILD KIT
Track days can be especially hard on the piston seals and dust boots in your brake calipers. Heat, in particular, will do a number on them. (Titanium heat shields behind your pads can help with that.) This kit is put together from the highest-quality components to rebuild a brake caliper back to like-new condition.
One kit is required per caliper (we suggest doing them both as long as you're doing it). Once you rebuild them, get the Ti heat shields as well and lengthen the interval between rebuilds. The shields and seals are available as a kit for convenience (and a bit of savings).
We only source superior quality brake components (brakes for track use are serious business); some kits don't take it as seriously. Any questions give us a call, we're happy to help!
