Got to agree on this, it's a good drive! Can't remember exactly where it is but there's a pub by some big cliff bit and there's usually a load of caterhams there.
Dude, a set of apex springs won't change anything you've mentioned. I say apex as they're cheaper, and on a non sport, they're entirely fine.
I ran them on my ph1 non sport, it wasn't silly low, didn't scrape, handled far better, and looked cracking.
