Progressive coil spring on torque link

[rubbinsracin]

i know the progressive spring has been talked abotu before, but i couldnt find anything that talks about which one to use. I have found some different options around and wondered what would be the best for a 602 car on a big 3/8th track that is pretty tacky all night long..

Here are the different things i have found 125lbs progressing to 500lbs, 225lbs to 500lbs, 200lbs to 600lbs, and a new one from afco appears to have alot more tightly wound coils that would give an even higher rate, but it does not tell what the rates actually are.

any input would be great. we have always just ran a standard spring under there ranging from 200lbs to a 450lb spring when we were trying different stuff.

I run the Afco progressive light spring. I love it in the slick! I am the only one to date that I know of that says this!

We also ran it all last year. Loved it.

Everyone we sold one too thought it was the best thing since sliced bread with the exception of a couple who thought we were snake oil salesman.

The looser the driver likes the car, the more they will like this spring.
