I finished assembling my TC5 and it was pretty straightforward - this is also my first attempt at building a car kit. I've pretty much purchased used cars in the past. This car is amazing. I'm extremely happy with the quality of the parts and I love the way the car drives.
I'm a little confused with FDR. I'm running a 13.5 BL system and I have a FDR of 4.8 If I go to a FDR of 4.5, does the torque increase and I lose top end?
