Steve Courtney's suspension upgrades

Postby Larry Jowdy » Wed Sep 19, 2007 5:42 pm

The bar connecting the drop links is 9/16” precipitation hardened 17-4 ph roughly 34-HRC. The center piece is roughly 2X the length of the outboard arms. The die springs top and bottom, have very linear compressive values.

So in operation should one rear tire encounter a bump the bar will absorb progressively the load until it reaches the center arm which further absorbs the load.

Under acceleration or braking the bar winds one way or the other depending on the load (that’s why there are two springs one top and one bottom) and they are independently adjustable.

Cornering loads are distributed diagonally across the car by the front sway bar but droop is still slowed or stopped by the rear droop bar (sway bar).

I made this setup some 10 years ago and have been very pleased with it. It may not be the be all end all but it sure telegraphs what the car is doing through the seat of the pants and the steering wheel and stops surprises.
