Nice looking cars you guys have. I have several of mine as I was going through all the spring changes but for some reason haven't taken one since I finished with the suspension. When the wind quits blowing trees over I'' take it out and get a picture.
I also installed the competition engineering J bolt traction bars. When I redid the rear springs and welded the spring perches I changed the J bolts for thicker U bolts as I couldn't get the J bolts to fit in after the mod.
I left out the rubber spring pads, couldn't get those to fit either. With the combination of no spring pads, solid body bushings, weld in subframe connectors, tubular a arms with the stiffer sprung coil-overs with adjustable shocks, new higher rate rear springs with new bushings and shocks, the car corners really flat. It starts to slide before I get much roll going around a tight curve at speed. When I first bought the car it rolled changing lanes on the highway. I think replacing the transmission mount with a boxed unit may have tightened things up as well.
One problem I had with the Moog springs was the springs in the boxes were not what was printed on the box. I didn't realize that until I installed the springs and the car sat at about two inches different height. Had to take them out again and return them.
I changed the alignment from stock as well, handles better and helped with tire rub. Had to take all the shims out on one side to get it, the other side is stacked. I don't think my frame is exactly straight, I did drop a plumb bob down from all the alignment points on the frames, marked the floor and measured. It's straight on the horizontal plane within a sixteenth, not so sure on the vertical.
Weakest Part of mine is the rear axle assembly, it's a 373 C clip posi from a 69 Camaro, I swapped a girdle for the rear cover but I fear if I ever get real good traction the thing will come apart.
