GiroDisc Porsche Caliper Stud Kit 6 – BCS-06 The GiroDisc Porsche Caliper Stud Kit 6 (BCS-06) 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. BCS-06 applies to the factory mounting position in these applications. A GiroDisc spacer conversion can require BCS-04 instead. 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-06 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-06 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 6 Specifications Manufacturer: GiroDisc Manufacturer Part Number: BCS-06 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-06 Four brake caliper mounting studs Four ARP 12-point nuts Four washers Medium-strength thread-locking compound One kit provides hardware for two calipers. Converting both axles requires two kits, and the front and rear may require different part numbers. GiroDisc BCS-06 Porsche Vehicle Fitment Front and rear (in specified factory configurations): 996 Carrera/Carrera 4 997.1 Carrera/Carrera 4 986 Boxster S 987 S and Cayman R Rear (in specified factory configurations): 981 Base/S 718 Base/S Fitment depends on the exact brake configuration, axle and spacer arrangement. 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-06 is intended for specified factory caliper mounting 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. GiroDisc Porsche Caliper Stud Kit 6 FAQs What does the GiroDisc BCS-06 caliper stud kit do? It replaces the conventional caliper mounting bolts in compatible applications with studs and removable nuts, helping protect the upright threads during repeated brake service. How many calipers does one BCS-06 kit cover? One kit contains mounting hardware for two calipers on one axle. Check which kit is specified for each axle before ordering a complete front and rear conversion. Where is BCS-06 installed? Its installation location is front or rear, depending on application. Use the vehicle fitment section above to identify the relevant brake configuration. Are the BCS-06 studs stainless steel? Yes. The studs use 17-4 PH stainless steel, and the kit includes ARP stainless steel 12-point nuts. Can I choose BCS-06 using only my Porsche model name? No. Vehicle generation, brake equipment, axle and any caliper spacers must also match. Kits with different numbers should not be treated as interchangeable. Will BCS-06 work with a GiroDisc rotor upgrade? Only when this part number is specified for that rotor and caliper arrangement. Check whether the upgrade retains the factory mounting position or requires spacers. Can the same stud kit be used on the front and rear? Some applications specify the same kit on both axles, while others require different kits. Confirm the front and rear part numbers separately. Does the kit replace the brake rotors or calipers? No. This is a caliper mounting hardware conversion. Rotors, calipers and any required relocation spacers are separate components.

A1-032 Girodisc 2pc Front Brake Rotors (OEM Porsche PCCB) FITS THE FOLLOWING CARS: Porsche 911 996 4S (OEM PCCB) Porsche 981 Boxster/Cayman (OEM PCCB) Porsche 991 Carrera (OEM PCCB) Competition Motorsport is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline. This Girodisc system upgrades your Porsche 981 or 991 equipped with factory PCCB brakes to a 350mm two-piece steel disc and aluminum hat. This two-piece floating rotor design will bolt directly to your Porsche front and work flawlessly with the OEM calipers. Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Girodisc rotors maintain the low rotational and unsprung mass of your PCCB rotors while being far more durable -- particularly when swapping wheels on and off at the race track. Combined with Pagid or PFC performance brake pads and Competition Motorsport RF-1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc. The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors. This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs. Sold/priced per pair.
