The GiroDisc BCS-11 Porsche caliper stud kit replaces the original caliper mounting bolts on the exact brake configurations listed below. Select it by vehicle, axle and installed disc setup rather than by Porsche model name alone.
Stud-mounted calipers use retaining nuts to secure the caliper on its mounting studs. This gives the brake assembly a defined mounting arrangement when calipers are removed during disc or pad servicing. A conversion to a different disc size can require a different kit, so both the existing disc and any caliper spacer arrangement must be checked.
Key Features
- GiroDisc caliper mounting kit, part number BCS-11
- Specified Porsche front or rear applications shown individually
- Supplied and priced per axle
- Separate fitment entries for GiroDisc discs and smaller original discs where applicable
Vehicle Fitment and Brake Setup
| Vehicle | Axle | Model years | Required brake setup |
|---|---|---|---|
| Porsche 911 Carrera S/4S (996/997) | Rear | GiroDisc disc configuration. Front/rear 350/350mm | |
| Porsche 911 GT3 (996.1) | Rear | GiroDisc disc configuration. Front/rear 350/350mm | |
| Porsche 911 Turbo (996) | Rear | GiroDisc disc configuration. Front/rear 350/350mm |
A listing for both front and rear means the same kit can be suitable on either axle in the stated configuration. One pack does not service both axles. These are caliper mounting studs, not wheel studs.
Compare the complete disc and caliper configuration with the exact entry below. A different original-disc or upgraded-disc arrangement can require another stud kit even on the same model.
