I am just finishing the panel replacement and will lift the body to redo the frame.

I am disassembling the frame completely . It already is P/S, & P/DB I am thinking of cahnging the springs with lower ones or should I do rear springs and drop spindels.

I know this has been discussed before but I have noticed in super chevy mag the last few cars they have done have just been with springs.

I figure since I have disk brakes already if I should bother with new spindels.

I was also wondering about the inserts for boxing the rear control arms??? Has anyone used them??


Any opioins on the drop would be good as well. I was thinking 2" all the way around.

The car is a 350/ 4 speed it is an AC car but it is all missing and I don't think I will be putting it back in.

Thanks Stephen

Stephen,
I am doing a tall spindle upgrade to mine right now. I also boxed in the rear control arms. I bought the parts from a resotration company and welded them in myself. The car isn't on the road yet and I never drove it before starting a "frame-off".

While I am lowering the front it's mostly due to the tall spindle and putting in a big block with new small block springs. That should be a good couple of inches lower. I don't believe in lowering the rear and plan on raising mine.

Now you will hear the guys that really know what they are talking about say that any messing with teh ride height will through out the alignment and wear tires faster etc. It's probably true. Anytime you modify an operating characteristic you take it out of the specification the engineers designed it for. Does that mean you can't live with the drawback? If you don't drive it as a daily driver you probably won't much care if you can get a good alignment on it.

I am also looking into reinforcing my lower a arms. I have read in here where some guys said theirs had cracked or broke. I am putting a big block in to add more weight, so a little extra insurance might give some piece of mind.

You know what is funny/interesting, is that we had several '50-'51 Pontiac Catalina Hardtops with Olds V-8s in them in the late '50s-early '60s, and cut the front springs and used dropped spindles, 2" to 4" lowering blocks in the rear, and had "Excellent" tire wear.

Seems now that we try to avoid all or most of the above, and quite a few of us "Fight" the tire wear that we have.

Interesting (?)

I have a 69 with the Edelbrock springs, shocks and the rear suspension and the car works very well. I have in the past boxed the factory rear arms and rebushed them and saw an improvement but when I went with the Edelbrock suspension package the improvement was great.
