Hi. I have a set of deep dish rims and they need wheel spacers as the fronts are fouling the caliper. I'm looking at 15mm spacers, and have seen that you can get ones that just have longer bolts through and ones that you bolt to the hub and then bolt the wheel to, like pcd adapters. The ones that bolt to the hub are three times the price of the others! Has anybody any experience with either and can you recommend any? Cheers!
