I figure if I need new pads and rotors, and new calipers are only a few hundred more, why not. This is not something I would go out and do just to do it (not with OEM anyways).

I did this once on a Honda, it went like this, you would upgrade to the calipers from a certain year acura that had dual pistons. the idea that dual pistons = better stopping. I needed a new caliper anyways. Upgrade was $100 more than I was going to spend. Issues installing and bleeding and being upside down aside. it was pretty cool and based on the concept an upgrade.


Now, having looked into this a bit, it seems the 3.0 and the 4.4 have the same size front brake rotors which means the rest of it is probalby the same. The rears seem to be the same size, but I did see a mention of better vented brakes on later models of the 4.4

Switching to 4.6/4.8 would probably require a new carrier as well as a new caliper, rotor, pads, etc... so thats probably not worth it.

on the e46 you could swap 330 brakes to the 325, but the parking brake didnt work unless you swapped hubs which got expensive. You also couldnt use the bigger brakes unless you had bigger wheels.

I assume that the bigger brakes on the 4.6/4.8 will have the same issues since I only have the stock 17" wheels as it is.

I will settle for just new pads and rotors unless the updated 4.4 rotors are really different and they just bolt on.
