As for fitment, I just mounted up some BFGoodrich Sport Comp 2's in 245/40/17, on 17x9 +35 RPF1's. These tires run wide, and are very square like the Star Specs.
So far after about 100 miles I have no rubbing, and my fenders are not rolled (also stock suspension). To be honest, after I mounted them I thought I would have to roll based on how far they stuck out .. but I think the smaller overall diameter is what saved me. I think if I was lowered at all I would need to roll the rears though.
Regarding aesthetics .. that is all preference really. The +35's look about the same as Delphi's car in post #1918 (the WRB with white wheels).
I had seen much wider tires on 8" wheels for autocross so I figured I would be ok. I'm not sure going 9" would gain me much in pure autox performance, but we will see. Obviously my stockers are 17x8 and the stock dunlops are 235 so I'm not sure I will notice a dramatic difference in feel while on the course (other than grip).
I went with the +47. I can throw some pictures up here once I get them mounted for reference. The aesthetic comment I made was sort of silly--I'm not really concerned about that since these won't see any daily driving duty.
