Rear wheel rubbing issues

[CoyoteCobra]

Hello

My cobra has bullitt replica 17" wheels that I ordered from Vintage Wheels. Vintage said they've sold the same wheels I bought to many A&C customers without clearance issues. I'm running 315/35/17 tires on the back. I noticed as soon as I put them on that the driver side rear tire was hitting the fender on just the slightest bit of deflection/articulation of the springs. The passenger side has clearance and I've checked the centering of the axle vs. the frame a bunch of times. It is definitely centered.

I am assuming that the reason why I have more clearance on the pass vs the driver is either I mounted the body off by a tiny amount, or that the body's driver side wheel well is slightly smaller. I've measured the axle's position vs the frame and it is definitely centered properly. I can't really see anything on the body that looks like it was mounted wrong either.

As a temporary fix I tried adjusting the 4 link to set the axle back just a tiny bit and added a 0.25" spacer which seems to have resolved the issue from what I can tell. It no longer has any rub when going over a bump or driving over something where it causes the rear axle to articulate (such as approaching an incline at an angle).

The thing that bothers me is that with the axle moved a tiny bit I think this is causing a some amount of bind from the triangulated 4 link being in a stressed position. Maybe that isn't an issue but I think it would make more sense to move the axle back forward a tiny bit and get wider spacers.

I'm curious if anyone else ran into rubbing issues with 315s on their A&C and if so what did you do to fix it? The 315s I have are NT-05 and I'm unsure if they tend to run a little bit wider than other tires.
