so I opted to buy this conversion since my stock chassis has worn down on my cyclone tc. I have been running the conversion for a few months now. I would say the car has been more consistent and predictable to push the car faster around the track. Also the belt flipping made it much easier to balance out the car.
I did find the car to be to flexy on a high bite track, so I opted to use the 2.5mm upper deck to compensate. I ended up buying the battery strap also. Got tired of constantly taping batteries.
overall I am happy with the purchase
