Need some spacers to stop some tire rubbing on the rear of my C5. Never noticed the rubbing before but there is certainly wear marks in the wheel well liner now. Just want to go with 3mm, 5mm, 1/4". Do not want to swap lugs.
I think 3mm will be fine but do I need Hub Centric spacers? Or just go on Summit and order some cheap universal spacers???

Anyone know of a good source for what I need?

I've used products from this company with good results.

Thanks. Ordered a set. Little more than I wanted to spend but not sure I trust the universal type. If the 3mm doesn't work, will toss them on the front and order some 5mm for the rear.
