OZ Pegasus Stock Body Fitment?
 

Just curious if you could avoid rolling and keep stock-ish camber with 17x10 +45 w/ 255/40 square
Seemed like a cool old-school/budget fitment.

Nice choice of wheels.

For reference I run a 18x9.5 +45 with 285/30/18 tires and will ever so slightly rub with a lot of steering input and suspension travel. Your wheels would be 0.5" wider however with a narrower tire so it's going to be close, very close call without any fender mods. What's your ride height?

I'm a sucker for classic 5 spokes. My car is all stock for now, but presume it were functionally lowered on coilovers.

Fairly optimal offset; still, based on my experience with completely stock front fenders you will have to run at least -1.5 degrees camber to fit a 255 on +45 offset and avoid the tire catching the unrolled lip when going up drives at an angle.

-1.5 front camber isn't bad at all for the street, just don't take the chance of running stock 0 camber and catching the fender lip. It will do much more visible damage than if you had just carefully rolled the lip in the first place (which I would recommend for the fronts).
