Looking for a little help.

I have been trying to set up my 06 for carpet racing. Car seems a little squirrelly whenever I need to get off the throttle. Rear end looses traction, the rear end wants to come around at half throttle. 3/4 to full power the car feels okay.

Is this the characteristics of the rear wheel drive or can it be corrected

My current set up:

- Carpet -

Front -
Blue spring
60wt - 2 hole piston
Stock shock mounting
Spec tires - outside tread glued
2 degrees camber (stock)
0 degree toe (approx)

Rear -
Yellow spring
40wt - 2 hole piston
Middle shock mounting
Spec tires
1 degree camber
2 degree toe in

Gear diff, very loose.

No sway bars.

Usually run an 03, talk about apples and oranges.

Thanks
