Equal front and rear Tire Width??

[Goosesdad]

Thanks in advance for any help here.

Looking for guidance on setting up my car with equal front and rear tire width (outside to outside)??

70 Camaro with DSE front sub and DSE 4 link. 335's on 18x12 Forgelines in the rear and 315's on 18x11 in the front. I've bolted up the brakes and wheel/tires in the front and confirmed that all clearances are appropriate. Good wheel to caliper and wheel to upper A-arm.

I don't have rear end in the car yet, on order but they are waiting for me to tell the them the wheel to wheel measurement. This is the purpose of this discussion.

With the front end set per the above, this would require me to move the rear tires out (and fenders) about 1 1/2" 1 5/8" in order for the tire width to be equal.

I'm OK with flaring the fenders, no issue there and of course I can have rear end set up at any width.

Again, really just looking for advice on set up of the tire width....should the front and rear be equal?
