Anyone got wheel alignment figures?

 

My Corona arms on stock spring with one coil cut off gave me-

 

Camber -15' (1/4deg negative)

Toe in 2.2mm

Castor 3deg

Cool finally got some he sigma arms, so to fit them its just grind down bushes and replace ball joints cause there stuffed?

Hey all, am looking around for some GE signma LCA for me ke55 if anyone has some or knows of a good wrecker in South East QLD. ive tried around and noone seems to have anything that old.

Fitting the longer LCAs will give you toeout. I didn't need longer tie rods for fitting XT130 LCAs onto a KE70, they just screwed out further.

 

I'd work on keeping the amount of thread inside the balljoint & rack end at twice the tierod diameter minimum. If its shorter than that then get longer tie rods.

Is it just GE sigma or any others modles?

I'm not sure which Sigma models azzy, but the half a dozen Sigmas at the wreckers have a couple of different lengths. The steering arms are also in different lengths.

 

We fitted the longer Sigma LCAs to the RA40 Celica with no hassle, just trim the inner bush length a tad. But then we had very little thread left in the Celica clamp-on steering arms, so after we did one rally on them I figured we would get some seamless tube and make longer ones. Sadly, no-one has a left-hand tap for threading the tube, so I headed back to the wrecker.

 

The long Sigma steering arms are the same length as the Celica, the shorter ones very short. No manufacturer seems to make longer arms, it is easier to make the balljoint arm longer and run a short ajusting arm. 90% of everything is rack and pinion now also.

 

I found the passenger's side steering arm on a Triton ute was 3mm longer, but they use locknut instead of clamps, so the overall unit becomes longer. They are being fitted now.
