@280Z-LS3 have you mounted the wheels with the flares yet? I'm looking to fit 315/30r18 in the rear of my Z (with Apex Engineered Rear Kit w/ coilovers) and am leaning towards the extra wide Marugen Shoukai Flare Kit. The description in the link indicates they will add 5cm of width on each side (1.97 inches). Any chance you can confirm fitment? Also, did you order Standard, Delux, or Special? They only have the Standard available for the extra wide, rear now.
