Does anyone know with certainty from experience, what other parts it would be necessary to change in order to adapt the 12" front rotors of the V70R AWD to my '98 V70XC AWD (with 11" front rotors). Various sources have told me conflicting info including some or all of the following: rotors, calipers & pads (the same as on my car?), caliper bracket, hub, spindle, spline and half shaft.
