OK, so the rare Achilles 255/35/17 that I wanted proved to be a bit hard to get. I could have gotten the tires, but I started to lose interest, really wanting the front to match the rear, and I think the AD08R is a better looking tire anyway.
So, final fitment is as follows:
F: 17x8.25 +25 w/215/40 @ -2.5° camber
R: 17x9.75 +25 w/245/40 @ -3.5° camber
A normal person should probably just stick to 8.25 front and rear so they can keep their camber normal without rubbing, but since I don't drive my car much, or push the car to it's limits, I don't think the increased rear camber will cause any issues.
The cool thing, if you're like me and like wide tires, is that the 245/40 actually looks wider on my Exige than my 265/35 does on my TL. There are 3 reasons for this:
- the specific tread pattern
- more tire visible (smaller Exige body)
- the wheel being wider on the Exige causes the tire to stretch a bit, making the sidewall visible from the rear.
The overall effect is fantastic IMO.
