How much bfh needed for 11's in the rear for a +42 offset Iforged Aero on a 99 ss with kdw's new tread in a 315? I Also have DMS springs on the car.

trial and error would be the best way to figure it out

Possibly none, but since your lowered definitely rolling the quarters.

You're definately going to have to cut/roll the outer fender lip. I only had to do mine about 1/8" inch. About 12" along at the top of the quarter. Not even sure if it was an 1/8", probably not even.

I'm only running a 18x10, with a 295/35/18 though. I know some people that rub on the inside with the same sizes I run. Though I have about a 1/2" of clearance, maybe a little less.

Oh, and I'm lowered over 2". I was lowered 2.5", but my fronts rubbed at the top of the wheel well.

Every car is different, which is the annoying part. I doubt you'll have to hammer the inside wheel well too badly. If you're lucky, you won't at all.

This would be a very expensive trial and error! Just trying to decide if I should order 11's or get 10.5's instead. The offset is pretty agressive!

I'm doing another set myself. 19s, and a new pair of rears with new offsets.

Going with a fabbed 9" shortened 2". Probably do 18x11s. Depends how crazy Vince will let me go with 10s/10.5s".

LOL trial and error would definately cost a pretty penny.

I have 18x11's out back and had to do nothing as far as bfh. I do, however have to roll my fenders. Don't ask what offset I have b/c at the time, Iforged wouldn't provide me with that info and I never measured. I'm running 295/35's. I need to go wider, but I'm good for now.
