Sagaris Steering Arms
Discussion

Zinc plating (especially with a nickel plating first) gives superior corrosion resistance to powder coating. Powder coating is great until damp gets underneath it from cracking or abrasion and then it eventually peels off. Arguably more important is plating is much thinner so will not mess with the dimensional accuracy of the part. Powder coating can vary in thickness depending on the operator.
Thanks Andy. Interesting point. Talking only from my experience on my Tuscan, the existing plated steering arms are completely rusted on all faces exposed to the elements, yet the lower arm that supports the plated bracket is completely fine and it is powder coated. Hence my original question.Sadly Stewart they won’t. At least, not where they are intended to fit!
Re. the plating, it depends of course on the quality of both. I have had some really crap powder coating that has cracked off in no time and just rusted up underneath. Equally I have seen some cheap and nasty zinc plating (the TVR arms you mention!) that doesn’t last 5 minutes either.
If these arms were powder coated, it would partially fill the location holes which would cause fitment issues, and doing the four bolts up could damage the coating causing water ingress.

Upgrade for a Tamora?
Ah sorry I’ve somehow managed to miss the whole mcm thing. A quick google has put me in the picture. Upgrade for a Tamora?
The sagaris arms work on some cars depending on wishbone set up, steering rack position, wheel type etc etc. As per most Tvr’s everyone seems different!
They are machined from 080A15 steel, or EN32B as it used to be called under the old BS standards. It's a commonly used free cutting bright mild steel.
I did think about a Titanium option, but the material cost alone would be eye wateringly expensive!

Could you measure how much the arms lower the track rod end compared to the straight arms please?
The offset is 25.5mm but the ball joint is turned upside down so the steering arm offset will be less than this. I am afraid I do not have the figures as I simply copied an existing Sag arm as these seem to be the 'go to' part. As said above the car's seem to vary a lot depending on age, setup, other mods etc so trying to find the perfect dimensions would be impossible unless a complete kit was developed and sold.
En 8 walks this. I use en 24 for shafts, caps etc. The standard items don’t feel like anything special. The stresses are quite low and anyway the item they are bolted to is soft as toffee. The pic of the produced item, reverse engineered or whatever it is called these days, looks good.
Just my bit anyway.
