Look on my Webshots web page.

I have my Mayhem setup on there. Some of the pictures are blurred.
I put two shims between ackerman and ball for turnbuckle. I also put one shim between front hub arm and turnbuckle balls on each end.
The trick is to have your turnbuckle keep the same angle of your A arms as they move up and down. That will control the bumpsteer.
