the rim barrel's or the cut nd shut?
i'd say that they shud be strong enuff as ppl get their rims widened for racing, sprint car, tarmac etc, same shud apply to the barrels.
falling apart and you would have a big reason to crack the shits, get ur money back and sue them, as thats pretty dangerous
unsure of warranty, see other examples that the company ur choosing has made, customer cars etc, and their reputation
