GiroDisc Porsche Caliper Stud Kit 5 – BCS-05 The GiroDisc Porsche Caliper Stud Kit 5 (BCS-05) converts compatible Porsche brake caliper mounting points from conventional bolts to stainless steel studs and removable nuts. It is designed for owners who service their brakes regularly, including track-day drivers and club racers. This kit is selected by the vehicle's brake equipment, axle and caliper mounting arrangement. The same Porsche model may require BCS-03 or another kit when a GiroDisc upgrade adds caliper spacers. Verify both axles separately. Protect Your Porsche Caliper Mounting Threads Repeated caliper removal means repeatedly threading a mounting bolt into the suspension upright. A stud conversion allows the stud to remain in place while the caliper is removed using the mounting nuts. This helps reduce repeated wear at the upright threads and makes it easier to guide the caliper back into position. The BCS-05 is useful during rotor replacement, brake inspections and other service requiring caliper removal. Its benefits are especially practical for Porsche owners who perform frequent brake maintenance throughout a track season. GiroDisc BCS-05 Features 17-4 PH stainless steel caliper mounting studs ARP stainless steel 12-point nuts Corrosion-resistant mounting hardware Studs remain installed during routine caliper removal Helps guide the caliper into position during installation Reduces repeated threading into the suspension upright Mounting hardware for two calipers on one axle Application: Specified factory caliper mounting configurations GiroDisc Porsche Caliper Stud Kit 5 Specifications Manufacturer: GiroDisc Manufacturer Part Number: BCS-05 Product Type: Brake Caliper Mounting Stud Conversion Kit Stud Material: 17-4 PH Stainless Steel Nut Type: ARP Stainless Steel 12-Point Installation Location: Front or rear, depending on application Mounting Configuration: Specified factory caliper mounting configurations Coverage: One Axle Per Kit What's Included With GiroDisc BCS-05 Four brake caliper mounting studs Four ARP 12-point nuts Four washers Medium-strength thread-locking compound One kit provides hardware for two calipers.
