Another quick update. Everything for this year has been ordered pretty much. I'm now trying to figure out some of the suspension tuning stuff based on 86 Wheel-It-Fit and some calculations based on formula I have from a friend (which I hope are relatively accurate). My goal is to only do a 1" drop from stock height, I'm definitely not going to be slamming the car to the ground.
Given a 1" drop front and rear (keeping stock rake), I think -2.5 degrees camber in the front and -1.6 degrees camber in the rear will get me where I need to be with both sets of wheels without needing significant re-alignment.
Wheels:
18"x8.5" Volk ZE40 +44 offset w/ 225/40R18 tires
17"x9" Apex ARC-8 +42 offset w/ 225/45R18 slicks (roughly 245 actual width)
I think with the 18s I'll need a 15mm spacer and with the 17s I'll need a 5mm spacer to get the wheels flush with the fender and accomplish an appropriate track width.
Given all of the above. Now I need to figure out three more things to buy for this year and get them ordered:
1) Need extended wheel studs (probably getting ARP 3" extended studs)
2) Thinking H&R Trak+ 5mm DRS and 15mm DRS spacers
Anybody have thoughts on brands of wheel spacers? I want something that's hubcentric and decently made, I don't want eBay crap. I did find that US Wheel Adapters makes custom wheel spacers (

EDIT: I ordered 3" UHL ARP extended studs and 5mm, 10mm, and 15mm custom spacers from Motorsport Tech. I decided I want to try less camber (-1 degree) in the rear as well which would need a 10mm spacer rather than a 15mm for flushness.
