I recently bought a Mini T with a Mamba set up. I plan to race offroad carpet this winter. I am new to racing, however I have noticed a problem with the front suspension....it binds bad and does noe rebound entirely. I have had the shocks off the car, the are free, and the front arms move about freely, but assembled together, and they bind.
Is this a normal problem...Any solutions???

That's not a normal problem and it's one you need to fix especially if you're going to be running a brushless motor. You say the arms are free and they fall to the ground when you lift them w/o shocks hooked up, right? And the shocks are filled with oil and the shafts move in & out freely? Are you running enough preload on the springs and are the springs stiff enough? Usually a bent hinge pin is the cause but that shows up when you take the shock off and move the arm. Check and see if the front shocks are mounted IN the front arms and not mounted to the back edge. A crooked shock is not a happy shock. :D
