This way is better than a rotating clamp as you won't get as severe toe changes with the change in camber.

Hey Panel can I have a copy of that picture too please

You could thread both the inner and the outer pieces of metal in the pivot. Next you could remove some of the threads about a 1/2 inch from the base of the adjuster bolt. You can thread the bolt through both pieces of metal but as soon as the bolt goes through the bottom bracket it will stop threading in since the threads have been removed. If you can place a nut on both the top and bottom of the lower plate you can "LOCK" them together to prvent the camber from changing. Just an idea...

I found this picture right here in the forums of a camber box.

The bracket itself is pretty easy to make. The hard part would be figuring out a good way to access the nut that replaces the threaded boss in the original mount. The porsche doesn't have frame horns in the way.

My bus doesn't have them that close either!!

For an IRS bug, I think you may have to cut a slot in the frame horn so the nylok nut could fit through. I would replace the pivot hex head bolt with a grade 8 bolt of equal diameter.

Lots of great ideas in this thread but I'm going to go the camber box route.

I'm going to try and mock the camber box up in the next few weeks. Unfortunately, I'll have to cut some access panels in the rear parcel tray as the body is already on the pan

My plan will be to keep the stock mounting points intact incase this project goes sideways :whoops: as I need to have it on the road at the fist sign of spring !

Here's another pic from the web .. this is Bugformance's red tube chassis beetle .. found on 55Superbeetle's site.



There are no frame horns that I can see but the camber box is there and the range of adjustment does not seem to be too large.
