'67 GTO LS3 Swap

[CFster]

Decided to go with a slightly taller tire (45 vs. 40). I think they fill up the wells a little better and made a big difference in ride.

Hey Colin I am finally going to order wheels and had one question....how much tire bulge do you have on the rear? I want to get as close to the inner quarter without rubbing and maybe leave a 1/4" or so for good measure but I really need to know how much tire bulge to expect with a 275/45 tire to ensure I get the backspacing correct.

Thank you again-Ken

Not much, but enough that it rubs sometimes - there's no way in hell I could get a 285 in there and not have it rub constantly. I don't know about other people. Mine rubs when there are more than two people in the car going around around corners "briskly". IMO, unless you have a Watts link 1/4" isn't enough clearance. The rear moves side to side quite a bit under even normal driving conditions - and you know what I bet the johnny joints are partly responsible. The factory arms and bushings bind, which is a bad thing in of itself, but the joints allow freer movement...
