I know it sounds crazy but toe has quite an effect on radial wobble. Try toeing the front end out 1/8 to 3/16. We fought it for half a season on my buddy's cutlass and it completely went away after moving the toe from in to out.

Toe out is potentially very dangerous.....and trust me I know.... I made a run with that condition and nearly lost it.....

I'd be very hesitant to try that....

No Toe-Out not a good idea!

I know one thing the first time it happens you’ll definitely be awake when it’s over.

A well known super stock chassis builder from Virginia way suggested the toe deal. We wouldn't have tried it if it was anyone else. It worked for us.

Something that's often overlooked with this problem is rear thrust . I've had several cars with this issue that squaring the rear axle in the chassis ended the wobble.
Unfortunately curing radial wobble is much like fixing the "death wobble " on Jeeps , there can be many causes from toe, caster , front to rear shock settings and even tire pressure..
I have also heard of trying the toe out solution , while I would NEVER recommend it ,if it solves the problem ,I would suspect tire pressure it be an issue.

Fought it mightily on a very well-built Cavalier GT car. Tried everything and could never get completely rid of it. Was sent to Mike Crutchfield with the promise that Phoenix drive tires would eliminate the condition and they did.

Hi John We have had this issue on several SS cars and by tightening up the front shocks , it eliminated the bounce or wobble. most racers run their front shocks on the lose side , I think. this was not at the launch, but going down track where the problem is ?? Thanks Bob

What pressure are you trying to run in the back tires.
