Boxster brake conversions for 65-89 911, 912, and 914 are a proven path to better braking. This section provides ordering and information on the calipers alone.

Complete Boxster brake upgrade packages including these calipers are available here…

Boxster brake conversions provide enhanced pedal feel, making it easier to modulate braking. This improves control and ability to feather the pedal when threshold braking. Enhancements over original 911/912/914 calipers -The 4 piston monoblock design provides an impressive visual update, and delivers meaningful performance enhancements over stock 911/912/914 brake setups.

The staggered-size piston design provides even pad wear. It accommodates a much larger pad area than “A” and “M” type 911 calipers. The large pad delivers longer pad life and lower point temperatures since the pad/rotor contact is distributed over a larger area.

Made of lightweight aluminum alloy, Boxster calipers are a monoblock design. This makes them stiff, with very little flex under pressure – eliminating the spongy pedal feel associated with more flexible designs.

Boxster calipers are paired with standard 84-89 24mm wide front and 20mm rear rotors. These provide enhanced thermal capacity compared with pre-84 911/912/914 rotors.

Our Boxster caliper upgrade packages retain the parking brake functionality, and even fit under 15 inch wheels without issue.
