Well I now have something like about 5,000km on the 5L.
A few adjustments have been performed and some of my findings, and those of others, have been incorporated both in the design and the fitting instructions. I have also fitted the car with 195/65 R15 tyres, this, in combination with the Suplex ride height adjustments, give me the ground clearance I need and excellent ride comfort.
The system has performed well without any problems on a fairly extensive trip across France (one week on tour) and in England (two weeks) and return via Belgium, Germany, and Swtzerland.
It is true that I have become so accustomed to it that I have almost forgotten it is there.
I have driven the car by myself and experienced excellent handling and ride comfort. I have carried both of us and an great amount of luggage for touring, and I have sat next to our PJB whilst he put the car through its paces (and believe me he does not hang about on his rough and undulating "test track")
I did want Jays to drive the car whilst I was in the UK but he is still recovering from his ankle injury, however he was a passenger in the car on the way to Prescott and in my two fairly slow ascennts. I think he was reasonably impressed by the ride comfort. Perhaps he could be persuaded to comment.
I have had some discussions with Suplex and may finish up fitting slightly higher spring rates in the rear to better cope with the loads I carry whilst touring. The increased rate will stiffen the car a little but not effect the comfort too much.
