Yeah, what he said. This question has been asked before, and it was said that they are not strong enough.
I doubt this is so. Give them a try, and be the first. The front wheel will need a different size spacer to fit. The previous 1000 wheels needed the front spacer modded to work. Someone should offer spacers to fit as they would be easy for a machinist to make. I am seriously considering giving them a try myself. '05 wheels with polished lip would be the ticket!
