I have a suggestion that will give your theory a little more factual 'weight'...

Your calculations should factor in the progressive spring rate of every aftermarket lowering spring on the market.

The current crop of lowering spring for the M3 will all have different progressive spring rates, so they will all behave a little different with the OE shocks and struts.

From my perspective, Dinan and Eibach got it right...and everyone else got it wrong.
I agree with my old buddy Lemans here, Dinan includes a camber plate that has been cut down by .3" and uses the e36 M3 bump stops which are shorter, this gives the shock more travel then a stock camber plate on the front.

I noticed on my buddies car his EiBachs didn't even really drop it too much so I guess that's good too.

My H&R Coils are just amazing, the handling on the car is much better then stock.

I know your going to make fun of me later Lemans, but here is a question for you, when I went from my 285/25/20s in the rear to 295/25/20s it feels as if the handling wasn't as good as before, could this be? I am running 255/30/20s on the front.
