I hope someone can help me out here. I want to put some 17" 5Zigen Copse on a '90TT , but they don't offer very many offsets in the 17". I ask a company about using spacers to clear the calipers and they told me the wheel would stick out to far and may rub the fender. Any advise from anyone? We're talking milimeters here aren't we? I don't think the spacer would make that much of a difference. The reason i don't want to go 18" is because they cost over twice as much as 17".
