Thanks so much for the info guys, very helpful.
The reason I'm putting this car together is because I had a drive of a modified TC not too long ago, it was fast but I told my friend who owns it a pan would beat it with the same motor! My friend took the challenge, he constantly goes on about how pan cars are 70s technology and have no hope against a TC! Anyway, building this car to show him otherwise! I might not beat him but I will put up a fight! TCs just look so overcomplicated! I understand they are good for rougher tracks but our local tracks are very smooth.
