rear spring question

[herminator]

Regarding composite rear springs, what to look for or avoid? Any comments on VBP vs. Muskegon? Thanks.

I've had a VB&P 360 lb/in rear spring in my 71 since the late 80s. It's worked very well.

I also tried the 330 lb/in unit for a short time but found the car works better with the stiffer rear spring so I reinstalled the 360.
