Question: difference between a TC3 and TC4
 

Can anyone tell me what the difference between a tc3 and a tc4 Im wanting a first time on road car and I have someone that has a T3 but dont know if parts are still available yet and wanting to know if it would be a good car to learn with instead of the TC4 cause I can Buy the TC3 cheap thank you for your help

Basicly its the same car
a lot of parts are interchangeable
the TC4 has more set-up options

so would the tc3 be a good introduction to onroad carpet racing

The TC3 was very good in its day. As usual, the pros made several changes to their cars by dremeling the center brace to move the batteries closer to centerline, replaced the stock steering rack with the NTC3 bellcrank style rack and other small mods. Associated basically took all of the mods they were doing on the TC3 and created the TC4. Either car is a good beginning car. Very durable and not alot of adjustability. Too many of today's cars are so adjustable that it's easy to dial yourself OUT of a good set-up. Best of luck and have fun.
