Interesting thread. I hope to make my truck handle much better then stock, but traction at the track will be one of my biggest issues. My motor should be making well over 500hp and I hope to run 12's or better.

For the front I've added tubular upper arms with 2.5" drop spindles and 1" drop springs. The rear has 4" drop springs and 1/2" drop plates and has an extra crossmember, the original leaf spring shock crossmember, and it has the coil spring crossmember. I have 4 new Doetsch shocks going on too. The trailing arms have been welded at the seams, about 1" every 1' or so and are mounted to the CPP crossmember that corrects the pinion angle for a 4" drop. I have almost 6' of boxing plates that I planned to add thru the center of the frame, in front of and behind both the trailing arm crossmember and the trans crossmember. Originally I was going to weld them, but decided to bolt them in with grade8 hardware so they can be removed if needed. I hadn't though about cross bracing them with tubing.

I plan to install a baffled fuel tank behind the rear axle. I mocked up my new LSx/200-4r drivetrain and found it to be farther forward then the sbc I pulled out. To correct this I've pulled the motor back out (finishing cam/springs upgrade) and purchased some plates that should place everything about 1/2" back of the sbc setup. My motor mounts offer a high and low mount position, and clear with enough in the high so I will also try the lower position to check for clearance.

I have been interested in a complete custom IFS with coil overs and rack and pinion steering at some point..and why I didn't by tubular lower arms. I want to replace everything (when my wallet recovers) that has to do with front suspension and steering. I have also planned to replace the rear coils with bags.
