I can't speak for the "FT TC4" But, you are not comparing Apples to Apples when comparing the TC4 to the PRO 4. Pro 4 Blows the TC4 away. Plan on spending alot of money on upgrades for the TC4 not to mention hours of Drivetrain Work. The PRO 4 has one of the Smoothest Drivetrains, out of the box! I have ever seen. The Pro 4 Shocks are the best on the Market, the Associateds are OK with Yokomo Caps.
