Hey Folks:
Does anyone know the bolt pattern and back spacing on the original campi group 4 wide body wheels? Both front 15 x 8, rear 15 x 11.

Bolt Pattern (PCD): Standard Ford 5 bolt 4.5" (114.3mm)
Any one know the best off set for a group 4 flared car. That would run 11" rears and 10" fronts?
I am thinking of sticking with 11" rear, as I am not sure what size tire would fit a 13" rear. Especially if they are 17"
Thoughts?

Jack,
For my GP4 I used the same backspace as my GT5 (the same 10x15 and 13x15 Campi's were used);
10x17 and 4.625" BS
13x17 and 4.75" BS
Two things worthy of note;
1. different wheel suppliers quote backspace differently, BS quoted above is to tire bead lip
2. More important than wheel dimensions is the flares, whether steel or fiberglass and supplier, as there are most certainly a number of variants offered. Fiberglass flare fitting is somewhat predetermined, but steel is very dependent on the fitting process as most need at least some metalwork. For a comparison I'd recommend dropping a plumb bob at the outer flare lip and measure the distance to the hub wheel mounting flange.
Tires for front are 275/40/17 and rear 335/35/17
The 'find' function can help you find some more previous threads on the subject;

Even with an 11" width rim you would probably want a 335/35 tire to get the right look and the rim will be seriously offset to fill the flare. FWIW I ran the 335/35 on a narrow body car with 11" rims.

Thanks for info.
I currently run a 335/35r17 on my 11" rear. I guess I was assuming that it would not fit well on a 13" rim. But I guess not.
Plus, thanks for advice on offset, that makes sense too..
Cheers

So did the GT5 have a 15x10" front and 15x11 rears?
Is there a factory spec sheet stating rim widths on here?

No, the GT5 came with 15x10 front and 15x13 rear, the quoted offset above are those for factory GT5 Campi 10 spokes.
