Interesting. I know what peoe are saying about spring rates. There really isn't a lot of info out there for a 'base setting' for a track or fast road car. However, when I bought my springs I spoke to Tony (nuts_rs) who does Tarmac rally in an RS1600i and he recommended, for a stripped out RS Turbo, on Leda coil overs, 8 inch 275lb front springs and 8 inch 180lb rear springs. This is far softer than any off the shelf spring kit, and the rear end felt light on the RST for the short time it was on the road. However, I can't help but think Tony of all people, would know what he's talking about, so is a softer spring better? I've heard of people running anywhere between 300-600lbs! And that's for track, not even drag!

I was aware of the raised rear suspension pick up points on the race cars. The pictures of the Brooklyn RSi show them clearly. Raised 25mm IIRC.
