Fitment and Compatibility

Front and rear kits are for use with ’97-’04 986 Boxster calipers (non-S type).

The front adapter kits are for struts that have 3.5 inch bolt spacing and bolt directly to front struts as equipped on all 911 cars from ‘77-’89 and 911S models from ’69-’76. Pre-‘77 front struts equipped on 912, 914 and non-S 911 have 3.0 caliper bolt spacing and can convert to use 3.5 inch 911 type struts, contact us for details. If your car is pre-’77 measure your front caliper bolt spacing to confirm the distance center-to-center, many cars have had later 3.5 inch struts retrofit.

The rear adapter kits are available with 3.0 bolt spacing for direct fitment to 911, 912, & 914 trailing arms from ’69-’89 including aluminum and steel trailing arms. Rear adapter kits are also available with 2.25 inch bolt spacing for direct fitment on ’65-’68 short wheelbase trailing arms.

Both steel and aluminum trailing arms are supported. Aluminum trailing arms require the removal of heat shield mounting ears for fitment.

Front kits are for use with standard type ’84-’89 911 rotors 911-351-041-23.

Rear kits for ’69-’89 are for use with standard type ’84-’89 911 rotors part 911-352-041-08. Rear kits for ’65-’68 use standard type ’97-’04 996 rear rotors 996-352-401-05 and 911 brake shoes 911-352-097-10.
