Would I have to drill out the steering knuckle mounting holes for the caliper bolts or does it bolt right on? I ask because I have 6th gen brakes on my car now and I did have to drill them out already.

Thanks

you gotta go backwards now. the Z32 calipers use 12mm bolts.

what kind of brake upgrades can I fit in the se 16" wheels or the g35 17" wheels?

the G35 wheels have tons of options. the factory 16" wheels have basically zilch.

thanks alot matt. I'm trying to keep the outside as stock as possible, but I guess the g35 rims won't give away too much

nah.. everybody and their dogs puts wheels on cars anymore.. I don't think twice about a car when I see aftermarket/non OE wheels on one.
