Will 2002 x5 4.6 front caliper and rotor fit a 3.0?

[epdarks]

I have stock 4.6 calipers front and rear if you are interested.

Well i am going to need them in about six months if I decide to go that route. How much are you asking and what is the condition? Rebuilt are fairly cheap with the core return but not sure if f i can get a core return with 4.6 / 3.0 swap at a parts store. Thanks.

Before you do a swap, I advise that you measure the diameter of the 3.0 and 4.6 caliper pistons. If the 4.6 pistons are bigger in diameter (total surface), more fluid will be needed to displace them the same amount, so, you will get a lower pedal with a longer stroke. Check if the 4.6 and 3.0 share the same master cylinder, that would be a good indication.

And even if they share the same piston surface, the diameter of the 4.6 rotor is larger. That will give you more braking power at the front wheels, but may disturb the brake balance F/R.
