Honestly the dragstrip would be a must have, but a racetrack is far more forgiving and you would be OK.
The best thing you can do is get under the car, grab the pinion flange (where the driveshaft bolts on to the diff) and push up and down. If there is a touch of movement I would not be too fussed about it (rubber compliance).
If there is a lot or it thuds up and down, you should put your name on the list.
