GiroDisc Porsche Caliper Stud Kit 4 – BCS-04 The GiroDisc Porsche Caliper Stud Kit 4 (BCS-04) 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. These are spacer applications. Factory-position hardware for these configurations is generally BCS-06. 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-04 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-04 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 GiroDisc caliper spacer configurations GiroDisc Porsche Caliper Stud Kit 4 Specifications Manufacturer: GiroDisc Manufacturer Part Number: BCS-04 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 GiroDisc caliper spacer configurations Coverage: One Axle Per Kit What's Included With GiroDisc BCS-04 Four brake caliper mounting studs Four ARP 12-point nuts Four washers Medium-strength thread-locking compound One kit provides hardware for two calipers.

The applications above are a selection guide. Confirm the part number against the current GiroDisc application information for the vehicle and rotor setup before purchase. Factory Mounting Positions and GiroDisc Spacer Upgrades Some Porsche GiroDisc rotor upgrades use caliper spacers to accommodate a larger rotor. A change in caliper position can change the required mounting hardware. A stud kit listed for a factory mounting position should not automatically be carried over to a spacer conversion. The BCS-04 is intended for specified girodisc caliper spacer configurations. Check the front and rear requirements individually, including whether the car has factory iron brakes or Porsche Ceramic Composite Brakes (PCCB). Installation Information Follow GiroDisc's instructions for thread preparation, thread-locking compound, stud engagement and nut torque. Confirm the required caliper spacing and hardware before installation. A technician familiar with the vehicle's braking system should perform the work.
