Girodisc D1-224 Alfa Romeo Giulia / Stelvio QV Front Replacement Ring FAQs
Are these compatible with the factory carbon-ceramic brake option? No. The D1-224 rings are designed for steel Girodisc two-piece systems only and will not fit the OEM carbon-ceramic setup.
Will these rings change pedal feel or braking balance? Not at all. They maintain factory brake bias and deliver a firmer, more consistent pedal feel thanks to the floating rotor design.
Can I use these for both daily driving and track days? Yes. They’re quiet and smooth on the street but engineered to handle repeated high-temperature stops during spirited or track use.
Do these require special installation or bedding procedures? Standard bedding is recommended — gradually heating the pads and rotors through a few controlled stops ensures even pad transfer and optimal braking performance.

Girodisc Front Caliper Rebuild Kit Porsche 981 Boxster S-Cayman S
$56.00
PORSCHE 981 BOXSTER S/CAYMAN S FRONT CALIPER REBUILD KIT
Track days can be especially hard on the piston seals and dust boots in your brake calipers. Heat, in particular, will do a number on them. (Titanium heat shields behind your pads can help with that.) This kit is put together from the highest-quality components to rebuild a brake caliper back to like-new condition.
One kit is required per caliper (we suggest doing them both as long as you're doing it). Once you rebuild them, get the Ti heat shields as well and lengthen the interval between rebuilds. The shields and seals are available as a kit for convenience (and a bit of savings).
We only source superior quality brake components (brakes for track use are serious business); some kits don't take it as seriously. Any questions give us a call, we're happy to help!

Girodisc GP-Series Pad FAQs
What makes GP35 different from street pads?GP35 is a dedicated race compound designed to withstand high track temperatures and aggressive braking without fade.
Are these pads safe to use on the street?They can be driven on the street, but noise, dust, and rotor wear will be higher than street compounds.
Do I need to bed these pads in?Yes. Proper bedding ensures consistent friction and prevents uneven pad transfer.
Will GP35 pads work with factory Brembo rotors?Yes, as long as the vehicle uses iron Brembo rotors and not carbon-ceramic systems.
Are shims included?Hardware reuse depends on the OEM backing plate system; inspect shims and clips before installation.

What brake fluid should I pair with these pads? A high-temperature DOT 4 racing fluid such as Castrol SRF or Motul RBF 660 is recommended.
Do these pads require a specific bedding procedure? Yes—proper bedding is required for optimal bite, consistency, and rotor life.
