The Racing Hart CP-035 in a 17X7.5 are actually a half a pound lighter than the Canterline RPMs in 17X7. However, the cheepest price I have found on them is $440 each. That is too rich for my blood right now.
I have a business with a resale licence. If everyone could agree on a brand, I would look into picking up the line and doing a group buy thing for my cost.
Some times if you can pick up 8 or ten sets of rims you can get a good discount.
I would like to find a rim that is light (13 to 15 lbs) and at or under $200 a pop. As long as it isn't butt ugly I really don't care what it looks like. I like 225/40 or 45 by 17. I don't see the point at going any larger, but I think it is a taste thing rather than a performance one.
