"220 is pretty soft compared to the 475's I'm running on the front of my 240."
Yes it is, since you are at essentially double my wheel rate. But we're getting into a classic apples and oranges comparison here... double a-arm vs Macpherson strut. I've never been around a 240 set up for competition, but I guess I'm not surprised that you'd have to run a much higher wheel rate.
And actually, I was mistaken about the front springs in my 142, they're softer than I quoted; I'm currently running 700's in the front (195 lbs/in at the wheel). I do have a pair of 800's for the front, but the car is currently on the 700's. At the rear I'm currently on 225's, with 2 other pairs for tuning purposes, at 250 and 275 lbs/in.
