67 rim sizes

Post by Mike.B »

Hi Gents,
I am keen to run 15x8 Superlite rims front and rear on my 67 Coupe.......New Rims I purchased have 4 1/2 inch backspace.
Car has Disc brakes front and rear, Rear has 5 leaf reverse eye springs, Front has lowered HD coils and Shelby Drop.
Is anyone running 15 x 8's all round?
What drama's did you come across- rolled guard lips etc?
What is the optimum tyre size?
Any feedback, advice or photo's would be greatly appreciated.
Cheers fella's

The brakes make no difference to where the wheels sit. The hat of the disc is similar thickness to the drum, so it is the diff width (axle to axle) that governs what goes on.

In saying that, if you are running the stock diff housing, then 8's are no prob with that backspacing.

The fronts will also be no issue if you follow the wheel alignment tech advice in out tech section. It is important that the wheel is "centered" in the arch.
