Rotas are not a custom wheel. For a custom wheel, I would use HRE wheels.
I purchased this set of Rotas simply because they looked closest to the wheels on SMann's demo car. I owned the Smart for 4 months while I was waiting for my next car to be built and delivered. It was something different at the time with fuel prices over $4.00 a gallon.
As far as wheel failures, I remember reading over the internet about a bad batch from the Rota manufacturer years ago. Have you heard of any recent issues?
Unfortunately, I have heard of wheel failures over the internet on HRE as well.
Still interested in any of my custom carbon fiber SMann parts?
