With a 4x4 caliper the actual pad doesn't cover the total surface area of the disc though, so effectively having anything bigger than standard 4x4 discs on the back of a 2wd is wasted!?
That's only if you have the 330mm (and is the reason I always steer people away from these, as they look gash after a few weeks, as these discs have the extra 30mm made up of disc material, so have 30mm of disc thatisn't used
) - the 300s fit almost perfectly

Also, you have the increased leverage and the improved cooling form a disc and bell arrangement
