This a great thred, learning heaps. I,m also interested to know what bump stear is.....thanks

hi guys here is a pic of the castor rods on my ute , the multiple holes on the body are to adjust the anti dive geometry . the rods have a left hand and right hand threaded adjusting shaft in the middle of them, and to add to bennys bump steer spacers , while they have a affect on the bump steer their primary function is to get the lca pointing uphill again on a lowered car to raise the front roll center back up to where it was , the bump steer is a secondary benifit.

I have also seen the castor rod modded so that it attaches to the LCA with a rose joint, this eliminates some of the problem with the angle changing as the LCA moves forward. Still have an issue with the castor rod not pulling straight where it mounts to the chassis though.

I had solid bushing on the inner of the lca and that made getting a bunch of castor a chore. Ultimately had to cut the bushin in half so that the front and rear of the bushing could rotate a bit. Also drilled out the "inside" of the bushing so that the bolt didn't have to line up perfectly except at theouter edgeof the bushing. Lots of grease. Car handled well.

It's quite common here tosee rose jointed bottom arms on race/rally 1200's. The problem that can be found though is as you pull the lca forwards, the castor rod angle alters, and becomes different to the angle of the bush pocket on the front of the chassis.
One bloke I met reckoned he used to use rack ends to correct that angle.

They are from B-Pro and are specific to the bolt spacing of the B110 struts [barrower bolt spacing compare to stanza]
From memory Datsport do some nice spacers for the larger struts...

nice bump steer spacers, where are they from? do they suit stanza struts?

Ange, here is a pic of the front end of my sedan as described in thread on page 1.

The stock castor spec is: 20' to 1°50' for Sedan & Coupe

The Van specification is better: Caster: 1°05' to 2°05'

This explains why some 1200s track better than others... at 20' there is almost no caster yet it is considered "in specification".
