2wd (cos) front brake setup, 4x4 (cos) rear brake setup...

v. cheap and it will all fit (with a tiny bit of fetling)

failing that just stick to std size brakes+calipers and use decent discs + pads

the std brakes on the XR4x4 are more than man enuf for the job they were meant for... i'm running a XR4x4 brake seup on mine (ie rear discs) and they will stop the car from 120mph VERY fookin fast.

and re my earlier comment, i meant that fitting those parts will be a complete waste of money on an XR4x4
