Its too optimistic to attempt 235 on the front at ET40 without camber plates. 255 rears at ET40 is generally a no-go. I'm sorry to say it.
Thanks for the feedback. I kind of doubt 245s on the rear, though, given that the 235s are already hitting the lips.
Looks like its time for some camber plates.
