So, a minor setback...
After spending $120 to get my tires swapped over to the new wheels, I started messing with the rear camber a little bit, to tuck the wheels in.
Specifically the left rear, as the right side looked to be cambered well enough already to fit the wheel. But even after that, the left rear still looked to be sticking out farther than the right.
Then I noticed that the lugnuts on the left wheel sat almost flush with the surface, whereas the right side stuck out a bit. Oh, I'd say they stuck out just about exactly as much as the outer lip did on the left side...
Turns out, they sent me two wheels with different offsets- One was a 40(as it should have been), but the other is a 22.
So now I gotta prepare for the nightmare ahead: pay to dismount the tire, pay to send the wheel back, wait for the new wheel, and pay for the tire to be remounted.
I have to wait for a response from the seller, but I don't know how much they will be willing to cover. Either way, this just sucks.
*Edit: I have already received an RMA and FedEx is supposed to pick up the wheel on Tuesday.
