I have gone through quite a few posts on here but can not find anything about the C60's that have the 5 lug front wheels. I have already planned to purchase new rear 10 lug rims when they become available at a cheaper price in the spring from wheels now, but the 5 lug fronts have me scratching my head. I can have them custom made for about $335 a piece but I would like to find a cheaper alternative if its possible but I'm thinking I will end up going the custom route. Does any one have any specs or info they could share with me on these 5 lug wheels?
