alloy wheel help size

[hough39]

my car is lowered by 40mm and im after a set of alloys to fit, what size alloys will i be best with 14" or 15" and also what is the offset?

[kie-1200sxi-shed]

15'' are best and the wheels off-sets should be between et45-49

having trouble finding any that will fit

bassically once your cars lowered your choice is restricted mainly to vauxhall wheels e.g cav slabs,fans,sxi,sri etc but there are some aftermarket that do wheels with a et45. however you can fit any wheels if your willing to roll your arches etc
