When I got my first wheel/tire setup for CAMC autox I went with a ZLE sized staggered setup because I believed 18x12s wouldn't fit up front on my SS 1LE, and at the time the Falken 660s in 315/19 and 305/19 were the hot tire. Now I'm running 295/35/18 RE71RS, on 18x12 they are definitely faster. Here's how I fit this setup on my car:
-Obtain a set of 18x12 et41 wheels, Apex offers a few choices.
-Install Vorshlag camber plates with the plates at the maximum camber setting and then adjust the camber to ~3.5 degrees at the strut. This will give you a bit more clearance than maxing out camber at the strut and then adjusting at the plates.
- You'll need the right spacers and studs. I got some inexpensive Titan brand 1.5" hub-centric spacers and hammered out the studs that came with them. If you have magride, you may or may not want to add a 3-5mm spacer as well, it will reduce how much you need to grind the strut. MSI studs are for Mustang GT, PN 10.0067, 97mm length. Also, use MSI lug nuts. The MSI studs fit in the holes the original studs in the Titan spacers were in without modification. It's a somewhat tight fit but that's a good thing.

- Grind the strut so you have a few mm of clearance or get aftermarket coilovers. If getting coilovers for a magride car, obtain a suspension module from a car WITHOUT magride so you don't throw error codes or have to use those stupid magride delete kits.
I have an SS 1LE, so it has magride, I'm installing MCS coilovers this winter but, but here's a pic of the install with the OEM magride struts. It requires a decent amount of grinding but not much different than an 18x11 with a 1" spacer that's commonly done.
