ss springs,pinion angle check

[mod38-1]

After putting in super stock springs I am doing a pinion angle check. I have searched all the threads and gathered info but would just like a double check on my numbers before I order shims.
The trans is pointed down 1.1 degrees,the driveshaft is at 4.5 degrees down and the rear axle is at 3.6 degrees down. After this I think I need a 2 degree shim to bring the pinion up this would give me a -2.7 pinion angle and a rough pinion to driveshaft angle in the 4-5 range. Does this sound correct? These numbers are with the front tires on ramps and the rear tires on blocks maybe 1 inch higher than ramps (all I had) and car empty with about 1/2 tank of gas. Thanks

All I know is what the Mopar suspension book says. 5-7* nose down. It's always worked well for me. Just get there however you can.

Your numbers are correct according to the way I understand setting pinion angle. 2.7 would be great for a street car. 4.7 would probably be preferred for a street strip car.

I wouldn't do anything to it. It's at 4.7 down and that will likely work fine on the street and be better for any track runs. IMO, 2.7 is not enough with SS if you plan on doing any track stuff.

Put it on the ground, then check.

Do you think this will cause any u-joint issues because like this it gives me (I think) a u joint working angle of 8.1 degrees (driveshaft angle plus pinion angle) or am I wrong? Thanks
