My car always liked 30lbs more on the Right Rear.

Your almost 40 now. Id go even on the rear weights and see if the car goes right or left. Then add preload from there. when on the scales, see what 1/2 a turn on the T bar does, then you can make small changes at the track.

Its nice to have the tbars to adjust the weight, but yes it does make the car look weird sometimes.

LOVE my ladder bars and rear coil overs for that ….LOL
