Wheel size/offset?

NorthStyle

First, 90% of the setups on those threads are not using spacers. With a properly sized wheel/tire setup they are unnecessary.

Second, if you're going for a "flush, concave look" the stock wheels aren't going to cut it regardless of how much you space them out. You'll only have it flush, at best. Also, I'm not sure why you're asking how the spacers are going to affect the offset. They will do the same thing on any setup you use similar to what they are doing on your current setup: lower it. However, if you did not know that (raising vs lowering the offset) then my apologies and now you know.

Finally, when you say "wheel wells filled with tire" do you mean you want a meaty tire setup, or do you want the tires to be stretched? Also, are you trying to stay with 18s or go up in size to a 19 or 20 (or some combination)? Do you want a staggered front/rear setup or do you plan to run a square setup? I do know that a 245/275 tire setup is pretty weak for these vehicles and isn't really going to fill out the wheel wells unless you're running an aggressive offset wheel.

By "wheels dip inwards" I'm going to assume you mean having negative camber? This has to do with suspension setup. You didn't mention if your car is lowered or not, and if so, by what method?


This. As you can see above, I'm just shooting in the dark. I'd go through those threads (again) and find one you want and mimic it as said by nizzan4u2nv. If you find one and the specs aren't listed, I'd post a picture of the one in question and ask if anyone knows the specs in one of the wheel fitment threads.
