GS Stance
My Forgestar wheels are OEM fit, because they are stock sizing without upsizing, and no request for custom (agressive) offset was requested/selected





its all just metal and studs really
I had asked kinda dumb question and couldnt delete.
I was concerned about torquing Spacer to Hub while it was in air, but for rear will use emergency brake and Fronts will put screw driver between Rotor to hold from spinning to torgue.
I think! LOL

Further, I didn't want to negatively affect scrub radius, although frankly, I don't know how great an issue that may be with our suspension vs say a McPherson strut type design.
8mm isn't much and I don't feel it adds too much leverage on the wheel bearings either, although frankly mine aren't OE anyway (track use killed them).
The 8mm spacers are just shims (not bolt on!) and thin enough to still allow the flange for the hub to protrude a little, to help with hub centricity, and mounting wheels.
To retain full thread engagement on the stock wheel studs, I use 'extended thread' lug nuts instead of extended wheel studs.The extra .30 length is perfect in that respect. https://shop.wheelacc.com/41138et-p7418.aspx
My track wheels, are wider of course, 18x11 front (315/30) and 18x12.5 (335/30), thereby filling out the fenders much more, but those are made with the correct offset...no spacers...withe object being no fender or liner contact at full suspension travel.
Also, using the same extended lug nuts (yes, I do realize open nuts are preferred for track), retains even greater than OE length engagement for this application, thereby adding additional strength without having to resort to extended wheel studs (which would look crappy with my street wheels.
I did at one point try a C7 Z06 (C6 ZR1/Z07) size setup as track wheels...but it was an awful experiment. It added a lot of weight at each corner. Moreover, this was not only unsprung weight, but rotating mass as well. Terrible downgrade performancewise. And, track tires in those sizes were prohibitively expensive. I guess I could have retained them for a street setup, but had a willing buyer and already had my OE speedlines, with tires for street, and still needed a track wheel setup...so was happy to let them go. They sure weren't the 'hot setup', but they did 'look' ok though...
Anyway...just thought to share my setup(s) experience
