Yes there was originally a TC4 Team Kit
There was never a full "FT" version of the tub Chassis but before the double-deck version came out a Team Kit with all the "FT" upgrades was considered an FT TC4...
Then came the RTR
Then the FT TC4 with double deck chassis with the top deck having the option for the 4 vertical stiffner posts.
Then there was a FT TC4 Asphalt Chassis/Top Deck/Center brace set which featured thinner carbon, thinner top deck without the 4 post locations and an "X" shaped center brace instead of the full rectangle...
And lately we have the reincarnation of the kit in the TC4 Club Racer.
