Neil - Are those Billet Specialites?? Look similar to my US Mags. I love the look and really considered buying a set but just didn't want to spend the money again. Plus, I really hate keeping the centers clean!


Here is my contribution to the 18" wheel thread

US Mag U202 18x10 5.75" BS front & rear (pass. side only for test fit)
BFG KDW2 295/35-18 Tire






American Racing Torq Thrust II PVD Finish 18x10 5.75" BS
Nitto NT05 295/35-18 - all 4 corners
This combo does very slightly rub the upper frame with the Nitto. I did not notice it with the BFG KDW, although that tire has been melted 1/2 way down too. I think a 1/8" spacer may remedy this, or if not, a few passes with an angle grinder should do the trick, I hope.

What is the backspacing on those wheels? Also what brand and size tyres are you running?

Thanks, Colin
BS is 4" in front and 5" in back. Tires are Falken 245/45-18 and 275/40-18.

Thanks, yeah me too! Unfortunately those were "borrowed" from the rear of my 70 Chevelle. I think they look better, and bigger (even though same size) than the Americans but also cost a good deal more. Plus, I couldn't have the exact same wheel on both cars.

I really like a soft lip on wheels as it just looks so much cleaner. American Racing make a few versions but most are forged and in the $6-800 per wheel range, which was more than I wanted to spend for this car.

Nothing up front other than the VB&P kit, to include monoleaf. It does run at about 80-85% full lock so keep that in mind.

Rear has offset trailing arms but I have been told they are not necessary. Sway bar does not fit standard location but many say the car is more balanced without it so I'll see if it modify one to fit or not. The rear tire did rub slightly on the frame but it appears a 1/8" spacer fixed that.

The only reason I even tried a 10" front was because of the RideTech 48 hour car. They are running 10.5" on all 4 corners with a 315 tire, which seems even more impossible.

For you guys running 5.5" BS, how close does the wheel sit to the frame just outside the front trailing arm mount? I'm only running 4.75" BS and I've only got 3/8" - 1/2" clearance to the tire at ride height. My car is very low though (10" bolts, 26.5" fender height).
