Monster 4 260mm to 280mm

The dimensions needed to fit these calipers are described below, there are 3 main dimensions:

“X” the P.C.D. (the distance between the 2 bolts).

“Y” the offset measured from the centre line of the disc.

“Z” this can be described as a plain, the distance from where the caliper mounts to the centre of the disc. This is sometimes known as the “PL” dimension. At HiSpec, this is never the diagonal distance to the mounting point.
