Agreed - Excellent feedback thanks. I hope the considerations we've made will address this, and I think we all support a low enough rev-limit to avoid problems. That extra couple hundred RPM really don't make the cars faster enough to justify it in a Spec class, especially if not having them makes the cars more reliable.
The balancer is really the only remaining piece, and it's not off the table as James mentioned. But my hope is that we get a few test cars running, built by people willing to experiment a bit, and see if that's truly necessary. Prices on these things have crept up and anywhere we can help keep that down would be preferable at this point. Ultimately though we won't sacrifice reliability if it comes to that.
