R: 18x12 +59, 335/30-18 Rivals, no rub at all. 27" rear ride height? Still in work due to coilover install but there's to much ice out.
Rear: +59 is stock. Even a 345x19 MPSS does not rub. A 335x30x18 is definitely not going to rub. And its 25.9 tall not 27. There is room to move the rears out some where between 59 and 50. Thats my question because I'm getting differing opinions.

Front: +40 is stock. Not sure about your front but you have a 10.5 and I want a 10 inch wheel. I'm being advised somewhere between 30 and 40.

Thanks

Sorry I got Bob to regurgitate again

Are any of you guys running 18x12 and 18x10 wheels. I would appreciate knowing your offsets. There seems to be a lack of consensus out there as to what is best. I don't want outside fender rubbing with 335 rears and 295 fronts. And I want to keep the basic OEM geometry......in other words I want the same front to rear stager (front narrower than rear)

Thanks

DH
Your post is a legit question, not regurgitate. Regurgitate are the guys who post "I KNOW" the Vettes are hub centric and never actually touched a hub or used a spacer or turned a lug nut themselves. "Some guy" told them.

I run 18x12" +48 with 335 Rival S tires front and rear with no rubbing issues, other than on the inboard wheel well from turning. I've considered going down to a +45 with my next set, but I do have a bit of camber in my car (-3*F/-1.8*R) which does affect how much they will rub.

Also 295 on a 10" wide wheel might be a bit pinched. I would run that on a 10.5 or an 11, personally.

Great info !!

That answers my question on the rear. A 50 offset should give even more clearance. Are you on stock suspension? Lowered on stock bolts?

Not sure how to evaluate the fronts with that 335 I assume on an 11 inch wheel and twice the camber I run.

Not sure if the F14 is available in 10.5 Some have said the same about slight pinching. Others have said they are fine and used successfully. They are recommended for 10-11 inch.

Thanks

Yep, a 50 offset should work perfect and give you a tad more clearance. I ran these wheels and tires on both stock suspension, and now on coilovers. I believe it was on lowering bolts, but not wound all the way down. It was maybe a half inch or so lower than stock in the rear, but close to an inch lower than everyone else in the front.

I measured for wheels before I added camber as well, and was getting around a +53-56 offset for them with little to no camber. So I would guess, based on those measurements, you would be good with a +40 offset in the front on an 11, or a +27 on a 10. And it should be fairly conservative with 1.5* of camber like you said, although with a pinched tire on a 10, you may want to come in slightly more, like a +30 or so.

You are correct. I don't believe Forgestars are offered in 0.5" increments, so you would have to go with a 10 or 11. I personally would go with the 11", if the plan is a 295.
