Measurements of Lowered Boxsters

[mn box s]

-Porpoising may not be the term, I read it a few places and it is close to describing what I have going on. When I hit a dip in freeway the rear of the car feels as if it lifts off the ground, and once I know for a fact it did. If I hit a bump the same thing happens it feels as if the rear of the car is near coming off the ground.


Have you ruled out hitting your bump stops? I have seen this occur under those circumstances.

Hitting the bump stops is a high possibility.
Now I will feel like a retard but I would assume if it was hitting the bump stops I would hear it?
The car does not make any noises from the suspension.
Is there a way to see if its hitting the bump stops?
