With the motor in the middle the car it doesnt throw the load around as much as a rear motored car. Its good for 10.5t etc but start getting in the realms of hotter motors (5t ) not having the weight at the back starts be be a disadvantage when putting the weight down.
I have a ta05, which has never broken on me
. I also have the ta05ms, the motor is about 3/4 the way in on that car (between a ta05 and a trf416 postion), so my entering corner speed is quite good and I can get good speed out of the corners. I only run on a small technical indoor circuit (9t) though. So the ta05 is really just as effective.
The only limiter I have is my thumbs
