Cal tracts

[Joe Marcinowski]

The starting point Calvert recommends is to use the hole that keeps the bar closest to parallel with the ground with the car on the ground and at race weight.

That's true,,, race weight also means having a butt in the seat,, whoever the driver will be. For a baseline start, they recommend front shocks full loose, rear shocks on tightest ext setting, put bars in upper hole with 1/16" gap preload- go test.
A. Hooks the way you want: good to go, no more adjustment needed.
B. Hooks but too much wheelstand: tighten front shocks.
C. Hooks but goes left or right: add small preload to direction it goes, until straight.
D. Hooks then spins: loosen rear shocks 1-2 clicks, til it stays on the tires.
E. Hooks but hits too hard: go to lower hole and repeat A-D.
Softest hit: lower hole- no preload
Soft hit: lower hole- 1-5 turns preload
Hard hit: upper hole- no preload
Hardest hit: upper hole- 1-5 turns preload.
Hope this helps,, good luck and let us know how it went. The Cal-Tracs is a great system, especially if you use their split springs and shocks. My 2 cents
