Yeah 2/4 sounds good, I dont really want to notch the rear anyway, but damn 4/6 looks badass...Theres a 06 by my house that has a 4/6 with 20s and looks super clean! I want to be able to get traction though so 17's or 18's is what im thinkin so I can get some good sized tires. Maybe something like a 295/50/18 in the rear and 255/55/18 in the front.
