Cotrol arms and trailing arms

[albawhore]

Has anyone in o2 land approached a fab shop about making chrome-moly arms for an o2. I am curious as to a ball park price.

fabricating control arms or trailing arms out of a Cr-Mo steel of and by itself will do no good unless you heat treat it afterwards. the relatively thin stock material wouldn't be difficult to attain adequate cooling rate from elevated temperature, but distortion MAY come into play.

it'd be more realistic to merely reinforce the factory pieces if you are so inclined.

btw, the additions of Cr-Mo to a steel is added to shift the 'cooling transformation curve' to the right thereby allowing one to attain a hardened structure within a feasible cooling rate, this is more important for thicker sections. Cr and Mo additionally combine with carbon to form carbides for strength and hardness.

why?

The fronts are plenty strong, and you can use a 320 rear if

you really want the extra beef...

imho.

Just wondering. I have some racing friends that remake all of there arms out of the stuff. Different cars though.
