Reply to "1969 IRS Question"

Maybe these opinions('cause that's what they are) were formed back when good gas, low-compression, and semi-hemi(a BS term if I ever heard one) heads were the thing.

A single spring plate is about 1/4" thick, right? And it is loaded in tension and compression longitudinally(fore and aft). Spring tension/suspension bump action is up and down on the edge. The singles are certainly vertically stiff enough.

The thing I may be missing here is THERE IS NO SIDE LOAD on the plates. There is simply no need to double up the plates on a car that is already lighter than the plate was designed for. I'm not a weight-weanie hole-driller like Al, but I don't like extra weight for no reason. And there's just no reason.

I've got zero skin in this game either. I arrived here on SOC even after my friend Stan. I don't nor will I ever own a torsion-bar-equipped clown car. I've got tubular trailing arms(light AND stiff) and coilovers. Side load is taken by the swing-axle tubes, or the TRAILING ARM DIAGONAL for you IRS guys.

Oh no, the heresy...
