Yes by having equal length half shafts between the transaxle and wheels will mean less torque steer.
Found this:
"DUDE..... It is mostly tangential thrust from the torque of the motor when hard accelerating !! What motor are you running? Is it a hot race motor? I had the same problem on my T-Maxx. Let me see if I can give you an explanation but there are several things going on at the same time here....
As the motor winds up in RPM, and the chassis (car) starts to accelerate, you are causing the suspension to "Lighten Up" or extend. As it does this, there is also a rotating thrust caused by the flywheel on the clutch shoes causing them to swing out and contact the clutch bell. Even though they make contact there is still a rotating force exerted on the clutch bell. This is kind of like a built up street car seeming to "dip" in one corner as the brakes are held and you tag the gas.
Still with me???
Alright, as you accelerate you are lifting the car up and lightening the force each tire exerts on the ground, but you are also adding this rotational force (from the flywheel and clutch) which will cause one side of the car to seem heavier than the other. What this does is make one side of the car seem heavier than the other and so it will get a little bit more traction than the other does. This causes the car to seem to "pull" to one side. What is actually happening it that you are actually "pushing" one side faster than the other because of better traction. This is mainly due to the Power to Weight ratio and also the acceleration ability of the car. "
