New wheels need your help

[Hayman]

Hello all new to the site and I just recently sold the covos that were on my car. I liked them but a neighbor of mine threw out the right price and now they are on his nova. I'd like a 15 x 8 rear to be able to run 275/60/15s. I wouldn't mind if I needed to roll the lip but at this time. But still unsure if I want to notch the frame rail for a bigger rim, something like a 15 x10? I'm leaning toward weld rts wheels I think... What back spacing or wheels do you guys recommend? I was wondering if anyone here had pics of the setups on their cars post them up! Billet specialties are also on the list.. 8)
