More coilover questions!

[andybug]

Having read all of the threads regarding this topic one question seems to have remained unanswered:
What happens if you just drop an adjustable beam as low as it will go, and leave it untightened and then stick coil overs on, to regain the height? Are the torsion leaves not just doing the same as the tie bars in the red9 kit?
Has anyone tried this.
As £300 for a couple of coilovers and a couple of metal bars seems a little excessive to me, when you can get a pair of coilovers for £60!
