bottom line up front: I'd like to build up a setup reference/database - maybe it'll help us as we try to dial in our suspension setups for the strip.
If you've plotted your suspension (http://www.baselinesuspensions.com/instant-center_general.php), can you post your info? If you haven't, consider doing it and adding your info here. I did mine with the car on ramps and subtracted the height of the ramps from my measurements...
Antisquat %: 105.24%
IC length: 45.89"
IC height: 9.53"
springs front: cobra jet (M-5300-Q)
springs rear: cobra jet (M-5300-Q)
airbag: NO
ride height front: 28.5" (measured from floor to top of fenderwell arch)
ride height rear: 28.5"
tire dia front: 27.1" (OEM pirelli)
tire dia rear: 26.5" (M/T ET street)
strut type front: strange single adjustable
strut type rear: strange single adjustable
wheelbase: 107.1"
center gravity: 21.125" (crankshaft bolt + 6" I need to find the source that mentioned this for OHC engines)
LCA relocation brackets: YES, BMR
LCA position: upper hole
UCA bracket: YES, METCO
UCA position: upper hole
pinion angle: -2.5deg
best 60' to date: 1.95 (last fall, driver mod needed and additional suspension mods completed since
http://www.s197forum.com/forum/showthread.php?t=82789 )
I know there are a lot of variables (weather, tires, track condition, driver skill, etc.) but it could be interesting to see if there's any correlation to 60' times and how the AS/IC plots. I've read lots of threads where folks list their setups generically (springs/shocks/tires/LCA position/etc.), but having the numbers to go along with it might paint a better picture.
some reference links here, I'll add more later:
