I'd bump up to atleast 15" wheels. Stock SS/442/GN/2+2 tires are 215/65/15 & would look better as the small 15" tire, 235/60/15 fits nice. Next would be 17" wheels. Regardless of wheel size try to stick around 26" tall tires (stock height for 14" & 15"), for width how low you go will affect that with more of front tire rub while turning. Alot of guys here have more in depth info on what combos works.
