Porsche 928S/993 P80 BBK Bracket Set
Want to just buy the brackets and source the calipers yourself. Here you go! 2 brackets, caliper mounting bolts are modified from the stock length and are sold separately.
These brackets allow you to mount a Porsche 928S or 993 caliper to your P80 Volvo using a 330mm rotor. Some users have found that the Boxter S caliper will also work with the use of some .060 spacers to center the rotor and minor modification to the brake pad retainer clips since the Volvo rotor is wider than the OEM Porsche Boxter S.
