Frequently Asked Questions

Will this fit my 2022-2026 Porsche 718 Cayman?
That year, make, and model range is listed, but the exact trim, axle position, rotor dimensions, caliper, brake package, and every application note must also match.

Can I use my factory calipers and brake pads?
Many GiroDisc rotor sets retain the factory calipers, but some iron conversions require a different pad shape or compound. Follow the exact application note for this part number.

Are these rotors sold individually or as a pair?
GiroDisc commonly sells these assemblies as an axle pair, but confirm the quantity shown for this exact part number before ordering.

Installation Instructions

Follow the current GiroDisc instructions and vehicle service information.
