2WD indoor set up soft vs stiff

[lee.romang]

I am racing a TM2v2 on a high grip, flat and fast indoor track and struggling to get a good set up.

I have tried stiffening the car and lowering it to get rid of grip roll and lose some front end but the car is still hard to drive.

Having spoken to a well respected F1 driver he suggested going the other way, softening and raising the car to make it more docile and easier to drive.

This is a completely alien way for me to set up a car on this kind of track but you have to listen to someone of his level.

Does anyone have any more thoughts on this soft vs stiff set up?
