I've had many Rota wheel sets in my life and I have nothing bad to say about it. It was there for me at the tracks and a few AutoX events. From experience, Rota wheels works well in low HP/Torque cars. I've seen them crack on Evo's and STI's in one of the track events that I attended to back in the days. At the same time, I've witnessed OEM and various aftermarket wheels go bad as well. Anything can happen when pushed to the limits.
The only time that I experienced negative comments about Rotas were from the JMD crowd. I never cared about what people said to me when I had my Slipstreams, I cared about what the wheels could do for me which was a lot at the time, when I was still in JC.
People have a budget, it's what you do with your budget that will make it count in the long run.
