@Mike, with 783 up front and rear in a coilover you have:

front ride rate: 2.3 Hz
and rear rate: 2.1 Hz

2.3/2.1 = 1.09 I think this ratio is one of the most important things when doing the suspension voodoo math. I am using a number really close to that ratio with just lower spring rates and the OEM motion ratios. The hope is to get the same under/oversteer feel. Our OEM ratio is like .90 which is pretty standard OEM street car setup.

BY using 672 front and 504(OEM rears)

I will get 2.13 Hz/ 1.95 Hz = 1.09.

This will prolly be a little loose till I throw a wing on. I use .62 for front motion ratio, and .62 rear(oem), or .73(Coil position) as my motion ratios. If I was going full track I would prolly move higher like you guys, but it's gonna be a while before that happens.
