Hi just had the "TRD/TOYOTA HELICAL LSD – LOTUS/TOYOTA C5X, C6X" from mokeywrenchracing.com installed in my car. When I got my car back decided to test out the diff by lifting the car up and spinning the wheel while the car is in 1st gear. The wheels moved in opposite directions, indicating that the car really has NO LSD. I'm not understanding how to test correctly? Any help would be appreciated.
