I wish I could find two people to agree on the best spring / shock combination.
My 4/4 grounds a bit at the rear.
Did your 3 Wheeler ground when you drove it up my drive, Donald? The only time mine did was when the man who bought it, a big chap, was in the passenger seat when we went for a test drive.
You were with Giulietta (who is not heavy) but also you had quite a lot of luggage (about as much, I should think, as it is possible to take on board an M3W). Your all-up weight must have exceeded that of me, my buyer and my M3W without luggage, so I bet that the back of your M3W grounded at least once.
