Well I'm not sure you can get the same effect from a video as in person. Especially driving it through a tunnel. I'll come along to a meet as soon as I can as you can check it out.
This is where I ended up with my ride height. This is as low as I can go whilst being able to drive it like I stole it over the worst local roads. It is more floaty, but it never bottoms out now. I was being a bit of an anti social weapon, going back and forth up some great country roads. Another pit stop, another pub...
Yep, it is daft fun to spank it now without fear of being bucked off the road! I may have a fiddle with making it harder just on the dial next. But that is easy compared to keep taking the wheel off and measuring the dampers each time! Half a day well spent though.
I tried doing that and failed. MY driveway is not dead flat, so depending on where I park I get different readings! What I did instead was to adjust the dampers so the front left and front right were exactly the same. Plus again for the rear. I measured the distance from the top / bottom of the damper to the spring seat facing.
A very rough guide is this... I can put both my hands perfectly horizontal and flat together, one on top of another, then just about fit my stacked finger tips inside the arch gap (between top of tyre and top of arch). So effectively the gap is roughly 2cm.
Your roads may be more forgiving than mine though. I did love how sharp it was at only roughly 1cm gap. But I'd probably have to live in Europe with perfect roads for that.
