Hardly most of the team, Craig had a Bomber belt on his rubber car to see if it made a difference. In mod you can't tell a difference.
The low friction belts will be a running change in production. I'm not sure which belts the new kits come these days. The older belt says UK on it, the newer one is UG if I remember correctly.
Even the stiffer belts are fine after they have been run for a while. I know it might take a while to run them in with a stock motor though. On the positive side they will pretty much last forever.
As for the parts durability, in my opinion the TC5 is one of the stronger cars out there. In Cleveland we ran new stiffer caster blocks and arms that are supposed to be more brittle than the standard parts. We didnt break a single part there. Everything will break at some point. It is a race car and you always have to compromise between weight and durability.
I'm not sure why the engineers chose the 6x10x4 bearings but in all honesty I dont think the size makes a huge difference on how well they last. The ceramic ones will make your drivetrain a bit free'er but will break more easily and cost 2-3 times more.
