For those pushing their Porsche 991 Turbo or Turbo S to the limit, brake fluid boiling is a real concern that can ruin your track day. When the heat generated by your rotors and pads transfers through the caliper pistons, it can cause your brake fluid to boil, leading to a soft brake pedal that just won’t respond. This is especially common in production cars, which often lack the advanced cooling systems and materials found in true racing setups.
Racing calipers typically utilize titanium pistons due to their low thermal conductivity. Unlike steel (52 W/mk) and aluminum (130 W/mk), titanium (6AL-4V at 6.7 W/mk) is much less effective at transferring heat. This means it keeps your brake fluid cooler, allowing for consistent braking performance even under extreme conditions.
The Girodisc TS-1740-4 shims are designed to combat brake fluid boiling by placing a thin layer of titanium between the brake pad back and the caliper pistons. This innovative design significantly reduces heat transfer, ensuring your brake fluid stays at optimal temperatures during hard braking sessions.
If you're planning to take your Porsche 991 Turbo or Turbo S to the track, these titanium shims are a cost-effective solution to prevent brake pedal issues that can lead to costly mistakes on the track. They are an essential upgrade for any performance-focused owner looking to enhance their braking system without breaking the bank.
"I installed the Girodisc shims on my 2015 Porsche 991 Turbo before a track day, and they made a noticeable difference. No more brake fade, and the pedal feel was consistent throughout the day. Highly recommend for anyone serious about their track performance!"
