I just got a set of slotted, cross-drilled and zinc-plated from iRotor and they are GREAT. I should have done this when I first my car!! The trick with getting the caliper apart is to take the cap off the master brake to release the pressure, just make sure you dont get any air back in the line but the calipers will open up EZ'er with the cap off.
They're nice rotors, look cool and all, and perform nicely, but they won't last longer than any other typical rotor made for our cars. I had em on my '98 ES with Bendix CT-3 ceramic pads, stopped on a DIME.
I have heard nothing but good things about iRotors. I have them for the rear, but haven't installed them yet. The only thing I don't like about them is the slot design. The slot should go all the way to the outer edge, but iRotors doesn't do it that way.
hmmm... i emailed irotors, and this was their response.....
With ALL cross drilled & slotted rotors (whether they are the iRotors brand or a different brand), they cannot be cut, turned, or resurfaced. Doing any of the three will compromise the structure and strength of the rotors. Once the rotors are done, you will need to move on to a new pair.
