Re: Coil overs or not ?

So my 150 over 200 springs would = 85.71 initial spring rate? I tried Nick's math after he posted that and thought something was wrong because I kept coming up with nothing resembling what it should be lol.

Yeah, whoops.

I put the plus sign and mulplication in the wrong place.

You did the math right, but your formula is wrong. Correct calculation for initial spring rate is :

Ki = (Km * Kt) / (Km + Kt)

Where:

Ki = Initial Spring Rate (of combined springs)
Km = Spring Rate of Main Spring
Kt = Spring Rate of Tender Spring

Hmm....so originally at 100/200, initial springrate was 66.67, and when I went to the 150 upper spring, that changed initial springrate to 85.71. More of a significant change that I had figured. Can definitely tell a difference with the 150/200 setup, it feels right to me.
