Issue found with Heidt’s Mustang II stock spindles

Posted on

We had a customer complain about one of our Studebaker clips not capable of an alignment recently. With all the shims removed from the adjusting plate, there was still negative camber.

I had to investigate further, and on a chassis we are supplying right now we had the same issue come up. This is brand new for us, so I needed to investigate. This is what I came up with. The upper ball joint bore is moved outboard about 1/2″.

This is causing a few problems, First off is the Camber issue. Second is going to be an issue of scrub radius. This may not cause any driveability issues, but you may notice a bit more wheel kickback on uneven road surfaces.

Short solution is to use a longer control arm, in some cases where the stock slot and T-bolt are used, you may not have much of an alignment issue.

EDIT:

I spoke with a representative from Heidt’s this afternoon. Of course this issue has never come up with them. He informed me they use a 1/4″ longer control arm at 8″ from pivot to ball joint. No reason given as to why. I want to caution everyone that if you are to mix-match parts, you may end up with a front end that you can’t align.

We have used the Heidt’s and CPP dropped spindles without this problem. I have used the stock height spindles from SPC and Kaiser without issue.

 

I want to go further with you as to what these changes will make to the way your front end will drive and handle in a future date. Right now I just needed to get this information out there.
