lowering z

[jamesj1996]

hey guys im looking to slam my z soon prob going with bc coilovers. i currently have 245-35-19 tires front and 275-30-19 tires back on stock oem rays. i also have 20mm front and 25mm back spacers (h&r) i wanna lower my car to the point where theres no wheel gap but 100% still drivable...i was thinking maybe 2 inches? 1.5 just doesnt do it for me . too much wheel gap and i have thinner tires so 1.5 wont do much. i dont wanna be rubbing or scraping on flat surface. i will attach a pic below of what i want me car to look like can someone tell me if i would need to roll/pull my fenders for no rubbing on my future setup? thanks in advance. i dont mind some camber
