There's something like 7" of compression from idle state, and it only takes something like 400 LBS or so to bottom out the rear suspension, IIRC.

I don't think it's the wheelbase that matters in that calculation, so much as the distance between the pivot point (front wheels) and the opposite end of the car.

The front wheels act as the fulcrum, the rear wheels are just providing resistance to movement (if you add weight to the back), so the final angle would be determined by the tail end of the car, if it makes a difference.
