I'm hoping some experienced builders can help me with questions I have on tie rods and center link design to minimize bumpsteer.
I'm designing these components for my 37 Buick similar to wiki: http://www.crankshaftcoalition.com/w...ension_upgrade
I'm using primarily GM truck components in my build.
I'm using a Saginaw gearbox instead of R&P described in the referenced wiki because I need more travel than a R&P can provide.
One circle track website I found discusses determining a tie rod length based on geometry and then aligning that tie rod so it passes through an "instant center" (point whereupper & lower control arms cross) to reduce bump steer:
Heidts describes how the Mustang 2 front suspension works and a different expalnation for preventing bumpsteer. It says the upper & lower control arms are parallel which means there is no "instant center". It describes a specific length of tie rod that must be tied in at very specific lines.
1) Are both methods valid?
2) Does anyone know which approach is used in design of a 70's to 80's 2wd Chevy truck?
