If you run your Porsche hard—track days, canyon runs, or just spirited weekend drives—you’ve probably had to remove your brake calipers more times than you can count. And if you’re still using the factory bolts, chances are you’ve seen the damage they can do. Over time, they start stripping out the threads in your uprights—an expensive part to replace for such a small fix.
That’s where the Girodisc BCS-08 Caliper Stud Kit comes in. Designed specifically for the Porsche 911 (991) and Cayman (981/982), this kit replaces the stock bolts with race-inspired studs. Why does that matter? Simple. These studs guide the caliper into place, making removal and reinstallation faster, easier, and a whole lot less frustrating. Plus, they hold up to repeated use without chewing up your uprights.
Made from heat-treated 17-4 PH stainless steel—the same stuff used in aerospace applications—they’re built to last and laugh off corrosion. Honestly, once you install them, you’ll wonder why it wasn’t like this from the factory.
