PM me your email and I'll send you a picture of a pretty trick Monte Bar on a Vega with a Rotary engine.

Resizing an image here is a pain.

I finally fixed the biggest scourge to early Chevy Vega Suspension. NO MORE AXLE HOP

Great detailed video on the old style 4 link wheel hop fix. I am curious how the 3 link with the panhard bar and torque arm setup compares. Did the engineers overlook the convergence angle that you describe as the cause of the hop when they re-engineered the 3-link design like the Cosworth used in 75 ? Also...all that work and you used the same ragged out bushings? Loved the 3-welds at once video shot. Killed it! Are you familiar with Jordy dot coms work? His dad was director of underwater photography on many famous movie sets.

I hear everyone suggest immediately to go to the three link as soon as anyone mentions wheel hop or that they have an early 4-link Vega. It drives me nuts because 4 link is the gold standard for aftermarket suspension setups. Why would I want to regress when I could add adjustable control arms and change a bit of geometry for infinite adjustability and have a bulletproof set-up? I can't speak to the convergence angle on the three link because i don't know much in the way of specifics or history on it. My theory on the four-link convergence angle is; they wanted the suspension to have as much "bite" as possible with the little 4 cylinder and went radical on the geometry to that end. When you put some horsepower to the tires, it has the unfortunate byproduct of causing the rear to want to squat and without the vehicle weight to put weight on the tires it unloads the tire repeatedly. The mod moving the convergence angle simply takes away some "bite." I also noticed that before the mod, the car squatted under power and now it lifts a bit. So, I think the axle drives into the ground more.

I never took out the bushings and I wanted to show it makes less difference about the bushings than the angle. So far, that has been the case. I don't even notice the wrecked bushings. I am considering some adjustable control arms so the bushings might be replaced with heims. Poly bushings at the very least. But all in due time. Electric power steering is my next project I think.
