Important notes:

• The calipers used must be the front calipers from the base model 986 Boxster, the piston sizing in the rear calipers will not work correctly though they are nearly indistinguishable externally
• The kit retains your existing flexible brake hoses. In some situations OEM type rubber brake hoses will not have enough slack to connect to the new location of the caliper inlet which is slightly different to the OE sliding caliper.  Aftermarket braided hoses typically present no issue as they allow more articulation in their mounting brackets.

Fitment information:

This kit is designed for the large hub/bearing type 4x100 suspension knuckle as fitted to many Civic and CR-X models from '88 to '00.   The correct knuckle has 242mm ventilated discs as OEM fitment.  This kit will not work on knuckles originally fitted with 262mm/10.3" brakes, the kit for the larger knuckle can be found here.  Given the wide variety of different model and trim levels that the kit suits throughout the world, please contact us if you are unsure of fitment.
