Tips for the track?

Pinion snubber was a cheap solution to a problem that is much easier and better solved differently now a days. A snubber is just too violent. Shocks are just so much better at controlling axle movement. You give me a “snubber” that uses an adjustable small shock and I would play around with it. Rigid snubber is just going to bounce the tire. A Caltrac or if you REALLY start hopping you can add a couple of leaves and clamp. Removing the rear clamps lets the spring fan out more. I don’t run any rear clamps,and I have had no issues on the street, but A bodies tend to separate a bunch already because of where the instant center is(front spring eye) gives them a high % of rise(they separate a bunch) controlling that gets harder and harder the more power you make.
