i guess this wont work for me.. i agree we need the 8.5 and 9.5 options for a track driven car.
So, as that post shows, yes, you will probably experience a little rubbing if you lower your car and run it on the track.
Here's some quotes from paintpro21 about these wheels, which is the info I was going off of:
18x8.5" et38 wheels fit up front with great ease and either 235/40/18's or 245/40/18's.
18x9.0" et42 wheels also fit up front without the need for a spacer with 245/40/18 tires summer tires.
255/35/18 tires can be run on this size wheel, but a spacer may be needed.
Negative camber and spacers may be required depending on the 255 tire run as r-compounds and extreme summer tires can run wide.
18x9.5" et35 & et22 two offsets available, both work well, but the new et22 offset is the best fit.
They can be run with either 265/35/18 or 275/35/18 street tires or r-compounds.
The 9.5" et35 wheel can also be used up front with 245/35/18's or 255/35/18's with added negative camber.
18x10" et25 fit the rear with 275/35/18's with ease on stock and lowered cars.
R-compounds may have slight rubbing on the inner rear fender liner material.
This is a foam sound deadening material that can easily be trimmed or ignored.
