I ran a Durango for the last 2 years and found them very good but i tried a Team C TM2 and instantly gained a full lap per race on astro. I still run 3 410`s mine ,my sons and my daughters.( in the process of changing them to TM4`s as funds allow.)
Depends on the driver ability, as i am average, a good driver will improve with the TM2 but not by as much as i did. Also compared to the Durango we have broken nothing in 8 months of running two TM2`s. Last week my 11 year old set the fastest lap of the day in his TM2 and he loves it.
The main difference i found was the end of grip rolling and much better consistency!
