I got a Speedway straight axle kit with Chevy spindles for the 55 Gasser project and the instructions say to use 6-8 degrees of caster. That seems like a helluva lot of caster to me. The stock tri5 spec is .5-1.5 degrees, and I know most people don't consider that enough. I was thinking 4-6 degrees would be plenty, if not a little too much already.

What do you guys recommend? I know it can be adjusted with tapered shims, but I'd rather get it right when installing the axle.
