What rear suspension for bracket racing.
I would use the Chassis Engineering Slide-A-links for a street car long before I used Cal-Tracks. They ride a bunch smoother.
If ride doesn’t matter I’d buy the Assassin bars from Smith Racecraft. I think that’s who makes them. Way more adjustable and I like that. But not over ride comfort.
If I was going to back half a car I’d skip the ladder bars and use a 4 link. More adjustable and easier to control than a ladder bar.
SS springs and pinion snubbers are meant for the museum.
Your best money will be spent on double adjustable shocks for the front and rear.
