Benifits of chromoly?

You may want to expand on your question.
I am assuming your having a cage welded and there are MANY benefits such as less weight over all compared to mild steel with affording generally the same amount of protection.
In general the point is to add strength and structure with as adding as little of extra weight as possible. That goes for all sorts of things.

A lot of people think Chrome Moly is lighter but that is definitely not the case, Chrome Moly steel and Mild Steel weigh the same. Chrome Moly steel is stronger so when building parts whether it be a roll cage, lower control arms, or panhard rod you can use a thinner wall steel which in turn makes it lighter. There are trade offs to using Chrome Moly steel over Mild steel, Chrome Moly steel doesn't have as good fatigue characteristics as Mild steel does. Chrome Moly is very hard which in turn makes it more brittle and rather than bend it is more prone to just break.

Chromoly is stronger than mild steel - given a fixed tube size (say, for a lower control arm), you can use thinner wall if you go chromoly over mild steel, and retain the same strength. That's where the weight savings lie...if you use the same wall thickness as mild steel, you'll end up with a stronger part, but the weight savings will not be there.
Chromoly is also usually tig welded, so it isn't quite as easy to work with as mild steel.

Having the car as light as possible is the name of the game, it allows you to put weight where you want/need it and thats only IF you need to run a given # due to class rules.
There are guys out there replacing EVERY bolt / nut on a car with Titanium or converting over to Chromoly rear ends.
Everyone needs to decide what is important and what they can afford as well as finding that balance that works for them.

Saving weight by using C/M really only comes into play when you using a lot of it make something like a cage. 1-5/8 x .083 C/M weighs 1.47 lbs a foot, compared to M/S that weighs 2.05 lbs a foot. So unless you are using a lot of it, the weight savings is very minimal. I believe with subframe connectors you really only save about 4lbs or less, but don’t get me wrong, saving weight is always good. C/M is stronger, but that is because it is a denser material. With that being said, if you are comparing a C/M 9in fab housing vs. a M/S fab housing, then technically the C/M housing will weigh more than the M/S housing do to the fact that it is a denser material. Not to mention, like stated above, C/M MUST be TIG welded, and it is not easy. I have heard of some ppl MIG welding it, but that’s probably not the safest idea. You spend the extra money for C/M then you create weak points by MIGing it together.

Race Weight is what we can shave off and its not about the pounds, its about the ounces we can shave and when your racing to win, price tends not to be as much as a consideration when your doing it for fun.
I have first hand exp. on seeing how much can be cut out of these cars and let me tell you there is not much left to it once your done but again it depends on how far you want to go...
