18's and 20's on a 69' Camaro

[T.O. Street Stalker]

Hi guys, after some time searching the forum, I'm not sure if im more confused or discouraged. I could also not be using the right search words or phrases, so I'm not sure why I haven't found the specific answers I'm looking for.

I'd really appreciate any help anyone can provide, as well as any pics you might have. I have a 69' Camaro that I'm looking to do a new set of rims and tires on. The car is stock as far as suspension, no mini tubs, disk/drum brakes. I'd like to know how big/wide I can go with an 18" front and 20" rear setup, as well as the proper backspacing. Ideally I'm looking for that "raked" look, with a deeper dish in the rear.

Again, thanks for any and all info.

Bryan
