Sierra hub measurements - KPI, castor etc
danro - 14/4/05 at 12:33 PM

Hi all

I have deviated from the standard book chassis in a few ways (sierra donor) which pushes me to check or possibly redesign the front wish bones a little.

What I'm after are the various angles involved with the hub, KPI, Castor etc.
If any of the CAD guys have already created a CAD drawing of the hub then this would probably have all that I need to ensure the correct positioning at the end of the wishbones.

Can anyone assist?

Many thanks

Danny

This is the only diagram I've ever seen:

If it helps - when you come to make your top wishbones you'll need to angle your transit drag link end to get enough movement in bump and droop.

I went for about 10 degrees and mine turned out like this.

Hope that helps too! Rescued attachment front susp.JPG

Brilliant. Thanks Jambojeef

Perfect timing too!
I'll be talking your advise as I had heard about this issue. Wasn't too sure exactly how to do it but your photo... speaks 1000 words.
Much appreciated.
