Wheel disk size
 

Hi i gotta question.. ive never really had to pay much attention to disk type/size before i got Akebono brakes on my 350z and my SuperAdvan 18' wouldnt clear the front calipers by a couple hairs... i sold the advans and rockin my 20's till i hunt down a nice set of 19s (almost wanna try n find a set of 370 nismo wheels) But..my question is.. would a "low" disk type/size on 19s be smaller than any 18 inch wheel? or im i pretty safe to get any disk type 19s and still clear the akebono's??
