Thread: tri-4 bar geometry

Tweet

Coil-overs are set at all kinds of angles. The ones on my '34 are inset 5-1-2" at the top.

There is an effect in changing the angle. The more the shocks are slanted inward, the less the shock action . . . vector mechanics works on cars too.

I think you're fine.

By the way, my theory is that the distance from the center of the left rear tire footprint to the center of the upper shock bolt should be equal to the distance from the left tire footprint to the center of the lower shock bolt. (Of course, the other side is a mirror image) That's based on the arc the axle swings when one tire goes over a bump, and the other doesn't. Probably overkill, but engineering school does that to ya.
