G Body 18 inch wheels- looking for options

[Twoblackmarks...]

By the way, I had 18*8.5 on all four on my 87`442, I dont think 9.5 would fit very easy in the rear without a frame modification. Atlast very Close. Is El Camino different?

I can try to find the spec and a Picture if you want, but it is "euro" spec with offset instead of backspace. I know it was ET15 rims (+15mm offset) And I did use very thin spacers.

I did put the specs out on G-body forum I believe.

Found the specs: It`s 18" x 8.5 front and back +20mm offset front and +25mm offset in the rear I needed the 10mm spacer in the rear or else it would hit the frame, in the front I did not really need the 5mm i put there.
(3.46 backspace front, 3.26 backspace rear whitout tires) This backspace I believe is probably just calculated from the rim size maybe, do not know. Maybe I measured from hub to lip of rim. anyway, as you can see I could not have much backspace in the rear without hitting frame. It was Stock 8.5" rear

The tires are 245/40 front and 245/45 rear

Here are 2 pics, this is how it looked on the car, but it is not the style you want? I was going to Paint them flat black and "unpolish" the lip.

I'm going to use 18x9.5, 285/35/18 in the rear 6 BS with a 60 inch rear
The front will be 18x8, 245/40/18 in the front 5.25 BS with spacer, and ATX spindles

I will trim the outside lip on the rear

Did you ever find the wheel that you were going to use?

I cannot comment on 18x9.5 fitment, but I can comment on 17x9.5. I have that with 275/40/17 tires. It is tight but fits, there is about .5" between the frame & tire. I rolled the fender lip also.




Be careful with BMW wheels. It is a 5x120mm bolt pattern, which is 4.7244 inches. VERY close to 4.75, and will mount, but look it up, a small amount off will cause stress on the bolts & has resulted in broken studs.
