Girodisc caliper service kits for the rear calipers in this range, in one listing. Choose your car in the Application drop-down, then choose the Dust boot kit (boots only – freshens the calipers without a full seal job) or the Complete rebuild kit (new piston pressure seals plus dust boots). Each kit services one caliper – order two per axle.

Track heat cooks the rubber dust boots first; hardened seals and boots slowly erode pedal feel and add pedal travel. All parts are made to Girodisc's specification in the same material and to the same standard as the factory components. Add Girodisc titanium pad shields to protect the new boots going forward.
Correct fitment depends on the caliper your car left the factory with (piston count, iron vs. PCCB / carbon-ceramic, caliper colour). If you are unsure, contact PHD Racing with your VIN before ordering.
