Car is not 60 footin as good as i think it should, wheels arent pulling as high either. Spohn Pro series torque arm, LCA, Relocation brackets, and Wolfe anti- roll bar.

Not sure about the whole "true pinion angle" thing. Got the Pinion angle at 5 deg. down, and the drive shaft angle at 2 deg. down. According to Steve Spohn that should equal -3 deg. down??

Any ideas or recomendations?
 
there is pinion and and driveline angle.
the way you checked yours is pinion.
I use driveline. I check diff between chassis(sfc) and the pinion.
madman uses this method too
whats your LCA angle?
 
Lets hear some numbers. Are you spinning just at the hit or does it spin 10ft, 30ft, 60ft out? Any wheelhop? What tire?

Remove front swaybar, relocate some weight to the rear, remove dead weight.

So using this driveline method, do u still make the difference come out to a 2 or 3 deg. down? And what about just putting the angle finder under the pinion yoke and setting that to 2 deg. down??

I dont know my LCA angle, but i have a moser 9 inch. and the control LCA are on the lowest hole.

Not sure if its spinning, just pulls wheels up couple inches and sets them right back down. I got best of a 1.56 on motor set up, running 11.00's - 11.20's

Front swaybar is gone already, 28 - 12.50 - 15 ET Streets
 
1.56 seems pretty good for those et's
convertor and gears will affect that too
yes nose down. -2 should be good with an auto
 
So ur sayin hang an angle finder off my sfc and under my pinion and set the pinion -2 down from the reading on the sfc? and this is all at ride height correct?
 
So i guess the numbers are right, just i thought it should pull up higher & carry out. I'll have to set it up on that driveline method and try it out, thanks!
