A few members here are running JBW RS 4 spokes, but you have to watch the offset with the 7" wide ones, as the tyres will rub the guards unless they are rolled. I've read reports of JBW wheels being your typical Chinese ¢r4p, but most of the compaints are about the finish peeling rather than them cracking. The UK is undoubtedly their biggest market, and I assume that the roads get salted in winter to deal with the snow, which can't be good for wheels, and of course isn't an issue in Australia. I wouldn't want to rally with them, as forged wheels are stronger and hence more appropriate, but I'd use them on the street.
