305's
 

i just saw a post from 08ivorypearl that said he was running 20 inch rims all around but said he had 305's in the rear and his tires were tucked into the fender what's the magical offset # to make this possible and would I need a 10.5 or 11 inch rim????

Do you have a sedan or coupe? I was running 295s on my 10 +45 on my lowered sedan at a camber of about -1.0. So a 10.5 +55 would get you there for a sedan, on a coupe you have about 10-15mm more room at the fender, so a 10.5 +45 would be about right or a 11 +50. If you ran more negative camber you could get by with a bit less positive on the offset.

Coupe
 

Thanks newt!

What offset
 

[img]webkit-fake-url://19c31278-4c4c-42b3-b7b4-43b727923824/imagejpeg[/img]Do you think these wheels are he said he is running 305s in back and really like the deep dish on the wheels looking to figure out his wheel setup so I can try to get something close on my car I have 285s in back stock height and I was rubbing before trimming my bumper attaching point a little so I know it's all an offset issue 285 wide is wide enough but I really like the look of his wheel setup I said -45 to -50 will that make the face of the rim all the way to the outside?

Those wheels are sunken in quite a bit, and hard to compare to your current stock height. That G is pretty slammed, looks like it might be a bagged setup. To get that fit you'd have to run pretty conservative offset, but trying to get that sunken fit combined w/ a 305 width tire is a no-go with the inner clearance. For a 305 to fit, your wheel will have to be right at the fender edge or poking a bit.

Ok
 

thank you!
