This absolutely won't work.
If you held the front wheels, the slipper can't possibly slip. The two center pulleys are locked together. If you do get the belts to turn with the front wheels and spur locked, your slipping both the slipper and the front diff. Your just messing up your front diff and your slipper will seem tighter than it really is...
This = FAIL!
To test the slipper's function, you hold the spur and one rear wheel steady. Make sure the front wheels are in the air, and turn the other back wheel. The belts should turn and so should the front wheels when you do this. Then you know your diff is set tighter than your slipper.
Typically you shouldn't have to repeat this step for the front diff because it's usually set tighter than the rear. If like to run both your diffs the same, then definitely check the front diff as well...
The trick is finding a combination of slipper and diff tightness that works well on the track. If you set the slipper too loose before you drive the car, you may run into trouble with your diff when you try to tighten it. This means you must start the process over...
