GiroDisc Front or Rear Brake Rotor Pairs for Porsche Boxster / Cayman 986 / 987

Select the axle and confirm the exact original brake package before choosing this GiroDisc upgrade for a 986 or 987. The front and rear options use different rotor diameters, and both require their corresponding supplied caliper spacers and longer bolts.

Before you order

Match original calipers and rotor dimensions to the selected A1-031 front or A2-031 rear pair. Verify the supplied spacers, bolts and wheel clearance; a base/S badge alone is insufficient.
