Is anyone on here familiar with suspension theory? Ive been doing a lot of reading on tech and trying to setup my suspension geometry (Drag setup). Im looking for insight on how changes actually effect a launch and where I should be for my setup.

4l60e, 4000 stall, stock 10 bolt, 315 ET streets

Front setup:
KYB AGX shocks, stock springs, no sway bar and significant weight reduction

Rear setup:
Spohn adj chassis mount TA, CM rod ends
UMI LCA poly/poly
LCA Relocation Brackets, bottom hole
UMI Adj Panhard poly/rod end
SFC's

Im going with summit 3 way drag shocks. I guess I'll start at 50/50 and see how that goes.

I currently have a stock sway bar and looking to upgrade to either a 25mm bar, fixed end links with an airbag in the right rear, or just go with the UMI 1.25" with adjustable rod ends...Opinions on that?

I never got the car scaled, but I found the Center of Gravity (CG), to be 59" horizontally from the rear tire contact (with me in the car). The vertical measurement of CG was set at 20" based on stock values. I never had the car on scales, so the vertical measurement is a ball park value to find the neutral line.

I drew this diagram in AutoCAD to get a better idea of what was going on. This drawing is to scale, and all the angles were found with a magnetic angle finder so it should be damn close to my actual setup.
