I run 305 30/19 on 19x11s all around. The front pokes about an inch with -1.5 camber up front. Front offset is +6, rear is +35. The rear pokes about .5". I pulled the fenders and plan on running -3.5, that should make it tuck in a bit better. I could have run a +8 or so and still maxed out the stock camber.
Reason I went +6 was some guys running oem ZL1 1LE wheels, which are +11, needed a 3mm spacer. It all worked out, the car is nice and grippy, now just begging for DSSV...
Wheels are Forgestar F14s. They are ok for the money.
