Auto-X / Roadrace rear suspension 1969 Valiant

@72bluNblu I agree. When I did the Cuda up with Reilly Motorsports stuff the choices for UCA were slim and they really weren’t a huge improvement over stock geometry. Overall, there just wasn’t a lot of marketing and performance oriented front suspension parts out there. Of course, there were parts in the Mopar world that could have worked well for a performance handling car because racers have been tuning the torsion bar system for a long time but they weren’t at all as prevalent and common knowledge. We didn’t have BAC, Hotchkis, SPC, Borgeson…..

Nowadays, I’m with you @72bluNblu . I have no doubt that a torsion bar suspension can handle with or, really, outperform a “kit” suspension. It comes down to tuning and driver skill. I am not thrilled with the choices for the rear “kits”. As stated I thought I was going to get a custom built 3-link for the longest time now. That is what Tom said he would have went to if he kept trying to be competitive with the Valiant. I have talked with him at length and made the moves he would have. Power, brakes, transmission, suspension, and was going to do the 3-link.

What can you tell me about optimizing the angle of the leaf springs in conjunction with sliders? Something akin to the angle that the E-body springs are at. Would that help. Would the sliders bind when leafs are angled?

Also, I will be calling two different composite spring manufacturers and getting quotes on 115# and 125# springs. I love the idea for the splined sway bar. All the pieces can be bought from Speedway for not a huge amount of money. Just have to measurement right the first time so you don’t have to repurchase links or brackets.

What is your thought on the panhard rod? I tend to think it would help. What are other ways to keep the rearend from going left to right?

Thank you very much for your patience insight.
