I'm surprised, given the original query was about ground clearance, that suspension hasn't been mentioned.
I have a 2013 4/4, bought in 2019, which from the start had suspension problem - hit a pothole it jumped sideways - so the SSL fix was fitted.
A few months later in heavy rain the factory fitted Continentals lost grip & we hit the kerb very hard. Matilda was recovered to the dealer nearest to home to be fixed. When I collected the car I mentioned that the rear springs were sagging so much that they hit the rear bulkhead on full compression. "Don't worry sir. I'll tell the lads to cut away the bulkhead" I didn't return.
After discussion with Jon at BCC and Dan White at SSL (who did the specification) I chose 4 seater anti-tramp springs which give 18-20mm uplift from standard (probably more from the crap that I had).
Further close reading of the instructions for fitting the SSL front-end revealed that there is a spacer which can be fitted above or below the stub axle. Below is what dealers assume, above gives 18-20mm more ground clearance!
The problem with the fix was that the "nodding dog" phenomenon (known issue with SSL front end) wouldn't go away. After a service at NewElms (second closest dealer) I commented that I liked Matilda so much she is my first choice for a drive. "wouldn't be if she were mine" was the lugubrious answer.
"can you fix her?" "Yes. Given a couple of days"
The solution was to rebuild the front end (it hadn't been done properly after the prang) and fit the Rutherford front end with the rebound springs shortened (to raise the front end).
Results are astonishing. No "nodding dog" and no scraping the tarmac (except for a couple of occasions on MCC trials)
