For me it was weight saving and ride. My project went from being teeth rattling uncomfortable to smooth as silk. It handles the curves better. The old spring was heavy duty and on twisties, the rear end had a tendency to want to snap around. With the compo spring the car is more "in the road" as it were.
Bottom line: go for it. You won't regret it.

Kid Vette,
Thanks for the pics. I have often read about the 10" bolt problem but have never seen an example. Your post shows quite graphically the potential effects of using 10" bolts with 15" wheels.

Quick, contact GM and tell them that they also did it wrong!!! Surely they will reward you with 5% off everything or something...

Nothing at all, and if you put the bolt in with the head at the bottom, you accomplish the same thing.

When I installed the VB&P spring in my wife's '79, I installed a 330# unit, per VB&P's recommendation. I hate to admit that I don't remember all the little details as well as I used to, so I can't say how long a bolt I used, but I'm really thinking that I kept the OE length bolts. I do remember using their 460# coils in the front, and cutting half a coil off them....
Any particular reason for the 355# spring in your car? Is is a big block car?

I'd like to see the after pic of the right/rear quarter when you have a second. I'd also like to see the shot of the bolts too.
The original picture looks like mine did before I replaced my original steel spring. My steel spring was overspung because she was used/misused as a drag racer at one time in her life. That is obviously not your problem. does you car have the rest of the weight of a spare tire?

Hi
Looks like if you need even longer bolts.
The halfshafts should be horizontal when the car stands on its wheels.
VB&P also offers low arc springs, specially to eliminate this high tail issue.
