I lowered my SS yesterday. I installed the Belltech 6400 parts kit and 2deg shims as well as cut the rear bump stops. I also turned the front torsion bars 6 1/2 turns on the front right and 6 3/4 on thr front left to even the front out. I know, I know, I need to show the pics, but the wife "put away" the charger cord for the digital camera, so no battery and no pics right now or ever until I can get to compusa and buy another one to replace the one she "put away."
I couldn't figure out how to reverse the helper spring, so I used my knee and lower leg as a lever and lifted the rear end springs and just slid the 2deg shims in above the assembly. It seems to be ok. I have only accelerated to 80 or so with no issues. I need to go today or tomorrow and get it re-aligned.
I did not cut the front bump stops. I like the way it feels. I don't feel like a 4 wheel drive (doesn't feel as tall.) Handles the large dips in the road at highway speeds a bit better on my seat of the pants o'meter.
One other note, I have the trailering package from GM. Dang, there are a lot of bolts to loosen to drop that tow bar so you can remove the lower bolts and remove/replace the shackles.
All in all, it ranks up there very well with the good mods.
BTW, the rear dropped 1.5" average and the front dropped 1.25" average. And my truck had the right side lower than the left, now only the right rear is lower than the left rear. The fronts are within 1/16" and I measured multiple times after several drives over bumps and around corners.
SeeYou guys should be proud of me.
