Forgeline has done the most work to get the proper offsets for a 10.5" or 11" on the front and rear.
here's a thread with tons of pictures of a member that is running 19x11's with 315/30/19's all around. Planning on running something similar.
Forgeline keeps the offsets secret, but I did some calculating on my own, concluding that you would need 25 offset or lower (with 10.5" wheels) to fit 305's in the front, and those will stick out a little.
This is untested, so i am not positive. not sure if it would work with oem struts.. camber plates will help. This is backed up by the fact that a few members are running 285's on 10.5 +35. pushing those out another 10mm should give clearance for 305's
If you dont wanna
or
then just give Steve Schardt a call and buy a set of forgelines
he has all the info ready to go.
