I did the same thing. I had to add 5/8“ spacers to the rear with my Vors wheels. Worked out nicely. Now the car a square stance. The rear end is as wide as the frontend.TBH I just ordered whatever I wanted and figured i'd add spacers if needed. First goblin all worked out great. Second I needed 15mm spacers in the rear. no biggy.
Don't stress! All can be easily fixed as long as you get the right bolt pattern!
Nuker-
I would like to edit my reply. I have the thicker Lower steel brackets. With them, my steering was limited by them hitting the jam nut on the lower helm joint. With a spacer washer on the bolt to clear the jam nut, the inside edge of the wheel DOES make contact with the lower arm and almost the upper arm by a few thousandths. You could squeak by with the 6.10" offset by extending both large helm joints out to move the hub away from the control arms but I will be looking to get the steering limiters now offered. Hope I didn't steer anyone down the wrong path.I have a 2008 SS/NA that probably has the SS rack. I have 17x8 with +40 offset or 6.10 backspacing. With 235/45-17 tires I have about 3/8” clearance on the back side of the A arm and over an inch on the front. I hope that helps.
