I emailed a very prestine member of ls1.com but incase he cannot return my message I would like to ask the group as a whole.
I want to have 275 tires on the front but realized that 8" wheels aren't big enough. And i wanan go 18's but the rim I want doesn't come 18*9 only 18*10. So heres my thoughts...

17*9 in front with 275/40/17(or 30/35)
18*10 in the back with 315/30/18

Is this a possible stagger? Or will it mess up my handling/driveability/car etc?

Or can I go with 18*10 all around?
