Description

Girodisc A1-031: front 340 mm rotor pair for 987 Boxster S/Cayman S. Increases diameter from the original 317 mm, using supplied caliper spacers and longer bolts for additional braking leverage and cooling capacity.

Two-piece construction uses a US-sourced 6061-T6 aluminum hat and US-made cast-iron ring with curved cooling vanes. Ten plated alloy-steel drive pins carry braking loads while allowing axial/radial float. Class 12.9 screws, hardened washers and anti-rattle spring washers retain the assembly. Floating action accommodates heat expansion and pad centering; the iron ring can be replaced separately. Sold as a pair.

Supplier part number: A1-031. Vendor: RSS (Road Sport Supply).
