The only issue I have with them is the change in offset (and narrowing the rim also) will potentially adversely effect the handling by moving the wheel well outside the centre of the effective centre point of the just like spacers do, I have seen many times have you seen it written that spacers made handling worse, well different offset/width wheels are just the same, Ive bought some 197 rims in need of refurb as winter rims for my 200 cup
How do you find them compared to a normal cup or 200 rim?
