I'm planning on an 18x9 F and 18x10 R setup. 07 Z4MC
I have the option to specify my ETs, so I'll ask the experts.
I would *like* to get 255s in the front and 285s in the rear. This is for a track setup on stock suspension (at the moment, though I doubt I'll ever drop the car more than half an inch, ever).
The question is: what ETs should I get for those wheel sizes, and what aspect ratio of the tires to get it close to stock? I'd do the math but the last time that happened, I...well, MATH IS HARD.
