Jesse on this board has q45 front brake setup, and had his rotors re-drilled to 4 bolt. We did a set of z32 rotors at our shop to go 4 lug. It can be done, any machine shop will be able to do it. Get a 4 lug rotor and the 5 lug rotor, one hole lines up and the rest dont. Mark them and drill them, or bring it to a machine shop. We have done this twice now sucessfully.
Hope this helps neejay
