The Highlander has a *different* braking system. Probably has different master cylinder, different proportioning valve and different rotor diameters. You shouldn't change *anything* without knowing what the front/rear bias ramifications are.

Also, maybe someone with actual experience in doing this can chime in, but I figured that even IF there was a bias change, stopping in DD scenarios will be largely unaffected.

If you put front calipers with significantly more piston area up front, you will TREMENDOUSLY affect stopping distances for the worse. At the point where ABS engages to reign in the overbiased fronts, the rears won't be contributing anything like as much braking as they would be with proper bias. In most instances, people won't continue to apply more and more brake pressure once they feel the ABS pulsing.
This mod sounds like a BAD idea to me. Basically, you'll engage ABS at much lower braking g's, and have to "push through" a fair amount more to fully utilize the rear brakes. Stock should already be a bit front-biased. Adding a ton more front bias? Bad idea... |
