Both cars need the steering upgrade kits and decent servo savers. That would be my first upgrade on both cars. Then the axle upgrade, and spring set. After that I would suggest the TRF shocks, a hex head screw kit and some suspension blocks so you can fine tune the suspension.
I've built and drove both cars. They are both very competitive and are just as fast as any of the high ends cars out there. The only thing that may hurt these cars on a club level now is weight. A lot of places are going down to 1420g limit which takes a little work to get the car down that light running a big lipo. The TA05 would be easier to get to 1420g. But its not a issue with me so much on my TB03 as the car still beats really light cars no problem. I don't have torque steer issues with my TB03 running 17.5/13.5. If you want to run mod, TA05 would be a better choice for most, but in stock classes both cars work great. The driving characteristics of the drive trains are.....
TB03- faster accelleration, faster brake and throttle response, requires a smoother trigger pull when driving. Shaft drive is aggressive.
TA05- Smoother acceleration, brake and throttle can be applied hard and the car stays pretty settled, if you pull the throttle like a on and off switch the TA will be easier to drive. Belt drive is more forgiving to fast throttle inputs by the driver.
For top speed I see no difference. I haven't been lacking of top speed in my TB03 on the straight aways. My local track's straight away is almost 200ft long, and against 009's, photons, tc5, whatnot, its never a problem for me.
In the end you can't go wrong with either car. They are both Tamiya
