This is caused by too much torque.  Try raising the number of teeth on
your pinion gear.  With as much torque as you claim to have, this will
add speed as well as control to the vehicle.
 
The basic idea here is that the wheels themselves will be putting out
more rpm's per turn of the motor with a larger pinion gear.  The more
times the wheels turn per turn of the motor, the more power the motor
needs to put out to turn them.  If the motor can easily overpower the
ratio, either the front end will lift off the ground or the rear wheels
will spin.  Normally, if your tires have proper traction, the front end
will lift off the ground.
 
Since your motor has lots of torque, it can often create too much
acceleration with a smaller pinion gear.  By increasing the size of the
gear, the torque is used more for speed than power.  The larger the
gear, the more speed you will get.  The smaller the gear, the more
power you will get.  What you need to find is the proper balance of
power and speed.  Ideally, your motor should have just enough torque
to make the front end of the car raise about 1/8 to 1/4 inch when you
open the throttle up.  You want it to pull hard enough so your suspension
will expand to the point where it is about to be fully extended.  At
this point you will still be able to control the car while getting
maximum speed and accelleration out of the vehicle.
 
You also may want to try rearranging the interior.  Try doing things like
moving the reciever to the front most area of the vehicle, to a place where
it will still be safe in a wreck, but so that it is on top of or in front
of the front wheels.  These few ounces will do an amazing amount to holding
the front end on the ground.  I wouldn't suggest moving the battery pack
towards the front because it may lighten the rear end too much and cause
you to lose traction.  With a high torque motor, you want to strive to
get the center of balance just infront of dead center of the vehicle.
 
Any other questions?  Feel free to ask.
