If you are hitting the bump stops, then the springs are too weak for the amount of travel you are allowing it. Aka short and soft springs.

I have H&R Supersports, and its shorter than Dinans, and marginally stiffer. I do not bottom out on my bump stops unless its a huge bump on the road. So depending on how large the transition youre talking about on your freeway, you may only have two options:
Either get more travel, usually by raising the car, or get stiffer springs.

The problem with stiffer springs is that our shocks are already under-dampened from the factory, adding my H&Rs on it was super under dampened in Comfort mode. Sport modes are the only modes I can drive in or else the car gets bouncy.

So if you want stiffer, you have to upgrade the shocks too.

Now you are left with, either ditching the adaptive and getting coilovers, or waiting until you have great grand kids for Bilstein's adaptive dampeners to go for sale in the US.
Thanks for the response. Still wondering if shockware might help. Doubtful but hopeful.
