My local track has/had a spec class with the Cyclone S. As it's a beginner class we get to see what breaks often. The C-hubs are made of eggshells. Replace them with the carbon graphite ones that come on the regular cyclone. The other main thing I would recommend is the BRP kydex bumper for the TC3 and modify it to fit. It will save you a lot of money and frustration in broken parts. We had some racers make front bumpers out of stiffer material and it lead to broken chassis instead.
