I'm hoping to run 18x10.5 25offset with 275-285 square. I've seen tons of people using 10" wide wheels square, so is 10.5 the limit or over the limit?

I'll be using TC Kline DA coil overs if that helps. Thanks for the help!

There are guys running 18x10.5 et 20-22 up front. The wheels I ordered should be around this size. I am going with a 275 tire up front.

There's a good chance you'll have clearance issues between the tire sidewall and the lower spring mount/locking collar on the front strut.

^This

I run 10.5 +20 and only have about a couple millimeters of clearance (OE struts). I'm pretty sure +25 wouldn't clear.

With such wide wheels fitment is tight and clearance will vary/depend on the strut. I personally have no idea if TCKs will clear but let us know

^ Are you able to fit 285s on the front?

I run 18x10 et25 with 275 continental slicks (which are as wide as many 285 street tires). Fits fine with a 5mm spacer up front to clear the KW CS spring perch. It fits OEM struts without spacer.

So there is a good chance I can get them to fit with 285s then! This is great news! I'd still like conformation if someone has done this. ^^^^^Thanks for the help guys!

Are you running a 275 up front? How close are you to the fender. How much camber are you running up front?

That doesn't say much in regards to OP's question. A 10.5" ET25 will be 11mm closer to the strut compared to your 10" ET20.

275s, yes.

Not sure how close. Haven't measured. Far enough that it doesn't rub. Close enough that it looks pretty good.

-3.2.

I think a 10" wheel is easier to fit on most suspensions, and easier to use more tire out off ie you could put wider tires without rubbing on a 10" ET25 but I wanted a square setup that works well AND fills the fenders (track camber sunks wheels in) without ever needing spacers. 10.5 ET 20 does it.

Haven't tried 285s yet but will.

Well then that definitively says that you can't run 18x10.5 on a KW CS setup (without removing helpers to raise spring perch). Mine rubs with no spacer and does not rub (by just a couple mm) with a 5mm. There isn't enough room in the fender to run a 15mm spacer or I'll hit the other side. I don't know how TCK's spring perch compares to mine, but I would be shocked if someone is running 18x10.5 et20 with KW CS and isn't rubbing.

I think I'm just going to run TE37SL 18x10.5 22 and call it a day....I've seen a few cars with that setup square. I know that I might have to get a little creative, but maybe not...time will tell. Thanks for all of your input guys!
