im thinking about buying them for the rear of my z. 295/40/18 . anyone have the 555g2's ? it's either the g2's or a set of the nt05's. the car is not exactly a daily driver but im concerned about the 05's in the rain and cold. can anyone give me an idea about the difference in traction? i figure i have a m6 - 411 rear and about 425 rwhp.
