Has anyone replaced the factory installed 100-6 front suspension springs with the BJ-8 setup?

Yup, direct replacement. I have since increased from the BJ8 400lbs spring to a custom 600lbs spring and now to a custom 800lbs spring on my '57 100-6 MM vintage racer. There's a 1" drop installed aswell. A complete alignment will be needed when your done.

Dougie,

I've made a set of tie rods that are adjustable like yours so I can experiment with use of an alternative Austin lever arm shock in search of a little more negative front camber .

My question is did you retain an original spec adjustable steering rod or replace that with a fixed length piece ?

Hi Andy -

I use the original adjustable steering rod with the addition of shorter Wosley Armstrong lever arms Chris Dommick sourced for me in Australia.

Thank you. I have the Wolesley shock's with shorter arms, I'd forgotten the source....anyway I'll continue using the original center rod.
Happy Holidays.

At some point during the 80s, these side rods were being supplied by the vendor (Southern Carburettors, maybe?). I've always managed to get the toe set/steering wheel centered with just the center rod, so I've never experimented with how much range the side rods have.



For camber correction, I made these out of UHMW at least a decade ago (>10 yrs) and they're still as snug as when I first put a bolt through them.

IIRC. UHMW Ultra High Moleular Weight Plastic. Very tough and machineable.

Ding! Ding1 Ding!

Correct, and I am impressed with the wear characteristics__I fully expected that these would need to be replaced long before now! At this rate, they may never need to be...

... although, I do have these waiting in the wings, just waiting to be fully finished to size!



And I guess these were older than I thought!
