I wanted to know if I should pay for the chrome moly or would I be ok with the steel. Is chrome moly lighter? Is that the only advantage? Looking to get adjustable LCA's and adjustable torque arm from hawks. Looking to use spohn cause I have the spohn subframes and love em! Is BMR better?

Moly will only be lighter if they used less material ie:thinner wall tubing. Same volume of steel and chromoly = same weight.
I dont know that any of them weld the material properly, even though they state otherwise, so I'll say the steel will give you less chance of failure.

Chromoly is stronger, in some respects. Thats why you can get away with thinner tubing, if its all put together correctly. They may not reach it (and I havent seen it in failed parts yet) but too thin and the tubing will fail regardless of it being stronger.

So should I go with Chrome Moly, or with the steel? Is it worth another $125 for a chrome moly torque arm compared to a steel torque arm?

Personally, no. I dont think its worth the cost and risk involved that it was made right... and the weight savings if any will be minimal. If you're trying to save every ounce then yes, otherwise stick with the steel.

Bingo! That's the answer I was looking for. Thanks. I know Spohn makes good stuff but I don't think it is worth the weight savings either. Any other opinions.

Ive heard that Chrome Moly takes stress differently than steel. Like Chrome Moly when damaged once, will completely break if it gets damaged again, where as steel would bend. Not sure on the validity on this though. I believe there maybe a post about it on here somewhere,

Chromoly has a higher carbon content and is more brittle than a mild steel. When it breaks it doesnt yield and then work harden and then eventually snap over its loading cycle, it just snaps once it yields.

I'm going to order steel components tomorrow from spohn unless someones says otherwise.

Please keep us in mind as well, we over a variety of products for the 3rd generation car including the torque arm. I think you will like our prices as well

Chrome Moly like mentioned has a higher tensile and yield strength than mild steel. This allows us as manufacturers to use thinner wall tubing to reduce weight but still maintain strength. The price increase of Chrome Moly is the material itself along with the fabrication time it takes when using it. Chrome Moly must be TIG welded due to heat and can not be MIG welded like mild steel... this increases time in building the item. Also it requires preheating before welding where mild steel does not.

If I can help anymore please ask. Thank you!
