18's

Has anyone got pictures of 5.1 on black or silver alloys, bought new one yesterday and really struggling with picking alloys, help!

Hi peeps, Got a T4 and wondered what size alloy wheels i can put on. I have heard you can put 20's on standard but i do a bit of motorcross so have heavy bikes in the back so wondered if 18's and a 50mm drop would be ok so they dont scrub. Does anyone have any advice or past problems they wish...
