Hey, I have an '04 G35X Sedan, w/o Brembo brakes (but I'm going to be getting some), and I'm getting new wheels/tires this summer.

First off, I'm looking at MRR GT-1s, 19"s
What width should I get? I know I need to do all the same all the way around, but should I get the 8.5, 9, or 9.5 widths?

Thanks,

Peter
