Funny thing: his car is too low at the back, I find. Waaay lower than mine and he reckons he's got them set at the max height.
I had a look and I could see straight away that his rear springs were shorter than my billies. My springs have about 6 coils, his 5. Not very scientific, I realise, but what I also noticed is that he doesn't have the secondary spring (the one that compresses fully and presumably is just there to stop the suspension rattling when you take off over humpbacks

Is something missing from his kit? Also, I thought H&R were ride adjustable, but his aren't. Do they do the equivalent of PSS?
