Talk to Roger Jones -Rog on TM - I have his Bump-stops fitted to my 2018 Plus 4 and this stops totally any "Bottoming out". I also think it makes the car handle bumpy corners better.
A friend had a lot of "Bottoming" issues and is delighted with Roger's Bump stops which he says makes all the difference
Cheers!!
An absolute must. A genius, simple fix.
