Some snaps took along the way going from stock 11.25" (285mm) to 12" (305mm) front rotors. I didn't plan to do this I was forced into going this route, cheaper than buying rotors from Volvo. Could only get 11" (280mm) or 12s. So, with the help of Maduko for the correct Volvo part number for the XC-90 front caliper brackets I was able to utilize the existing calipers.
It is a 81 244 sedan, running a B28 V6, monster cams, Motec ECU, Getrag close ratio 5 speed, custom stainless steel extractors, custom bmw Gp A M6 clutch. Coil over front suspension, 4 spot volvo calipers front and rear.
