1st Gen F-Body spring rates

[Jay Hilliard]

Scott,

I have not scaled the car. I'm still in the rebuild mode. I felt the 600# springs were a little too stiff, but I didnt have nice shocks (koni, bilstein) to compliment the springs. I do plan to scale the car though.

I am running 175lb/in Hotchkis leafs in the rear.

Another thing I plan to do is actually test the spring and find out exactly what the rate is. I don't expect much of a difference between the two springs, but it would not shock me if the 575# spring actually rated 570 or 580.

However during my circle track racing days, afcos and hypercoils were closer to advertised rate and stayed there (no spring set).

I will let you know what I find when I get to that point and please do the same.

Jay
