hey all, i want to put some 225/40 R 18's on my vectra SRi but am unsure about a couple of things. Firstly, the owner's manual indicates that the largest wheels my Z22YH vectra can have are 225/45 R 18's... Im assuming that the ones im after will fit since they have a small aspect ratio? Also, since the SRi has lowered suspension compared to the other vectras, will these larger rims cause issues between wheels and bodywork? Any help would be great thanks! :thumbup:
