TJ's truck has the fronts from a late 70's 1 ton on the back. It is way touchy....I have come in hot to an intersection and the light changes. No choice but to stand on 'em hard....once they lock, it's tough to get unlocked and back to a reasonable braking situation.
Everyone looks when you fly up to an intersection with the rears locked and the old MT/R's squealing like a mother.
