Default Currecting Pinion angle?

Other then an adj. TA or LCAs, is there another way to take out some pinion angle, i'm at around -3.5 according to my measuring, driveshaft upword pitch is 3, rearend is pitched down 1/2, would this be -3.5? If so, how can i get it to around -2?

NO there is not any adjustment in the factory suspension.

I know -2 is what you want for a street/track car but what about a more cars main goal is drag racing and ver little street use.

Well i'm just over -3, i have no vibrations on the highway, i'm running all polly bushings, if i can't change it other then those 2 parts, i'll leave it alone, i can't see spending 200.00 or so on LCAs too take out 1 deg. of angle, my joints are the solid ones, i'll just keep my eye on the rear one.

You are searching for a -1 final drive (meaning when under full load) So if you have rubber bushings then you should be about -3, And If you have poly then -1 - -1.5 is what your after.(less deflection)

You want the pinion and d/shaft to have 1d difference so the ujoint needles will spin. If the angle is straight then they wont spin. The ideal situation it to have the d/shaft as close to the pinion angle as possible w/o being exact.
