I certainly do bottom out the HBSes regularly, just by driving on a highway. As far as I understand how HBSs work, the difference from regular bump stop is just that when a HBS bottoms out it doesn't bounce back (it absorbs the energy through viscosity and converts into heat) as a rubber bump stop (which releases the potential energy back to the car body).

Basically it's like dropping a sandbag on a hard floor vs basketball. It's not some magic pill to prevent a damper from bottoming out though.
Please correct me if I'm misunderstanding how HBS works, preferably with references to TEIN public technical info. |
The HBS engages on compression only, and only at a high enough piston speed, at a designated part of the stroke range (at the upper end of shock travel).
In particular, this allows for rally cars to run very long, low rate springs, to have huge droop travel, without bottoming out when landing from jumps!
This video better visualizes exactly what the HBS does.
