Mono vs. Multi-Leaf springs???
 

What's the story with mono- vs. multi-leaf springs on F-bodies. . .especially with regards to Auto-X use???

I have a 1967 Pontiac Firebird and I'm going to be replacing the leaf springs. . .I can stay with mono leafs or a I can switch to multi-leafs.

I know in the off-road world that a leaf spring pack with many thin leafs is more desirable than a leaf spring pack with a a few thick leafs.

Thanks for the help.

What works for off-road use has no bearing on how you make a car handle well in autocross or street use. There is much more to making a car handle well then just leaf springs. Take a look at the RideTech Street Grip system which uses composite leaf springs, among other things, to give you a complete well matched suspension system with out breaking the bank.

I realize that comparing off-road to a track car is comparing apples to oranges. . .

. . .what I really wanted to know about was why some of the First-Gen F-bodies have mono-leafs and others have multi-leafs?

Is there an advantage for one over the other in a near stock car?

I am currently installing Energy Suspension poly bushing kit, Koni shocks front and rear, taller front spindle with improved steering geometry, increased rate shorter coil springs in front, 1 1/8" tubular front anti-sway bar, solid aluminum body mounts, 17x9" wheels with 265/40 front and 275/40 rear tires, and Kore 3 GMSS 325mm C6 front and Kore3 305mm C6 rear big brake kits. . .what's really left is just leaf springs.

This is my starter set-up to learn the car and auto-x for the first year or so. . .then I will be going with either a complete DSE front end (including their spindles) or a SpeedTech Performance front end and a 3-link with Watt's linkage rear end and coilovers all around.

So if anyone would like to chime in on the multi- vs. mono-leafs with regard to First-Gen F-Bodies and Auto-X I'd appreciate it.

Thanks!

Some good info here:

Multi leaf springs can be set up to give a progressive spring rate. Whether that is good or bad is discussed quite a bit.
