There is about less than ~1# of weight difference between 1' of 4130 CM and 1' of .134 wall ERW (MS). In an 8-point cage the difference is probably only ~20# or less and 4130 is several times more expensive than MS.
If you're to the point where you're only doing mild weight reduction and leaving glass in the car, don't waste the money on CM.
All steel has virtually the same density. The rollcage will weigh the same no matter which steel alloy it is made of, assuming the same dimensions. If you use a steel alloy with a higher yield strength, then you can use a thinner wall thickness and the rollcage will weigh less. However, the rollcage will be less stiff. The modulus of elasticity of most steel alloys is the same. Use a thinner wall thickness and the cage will be less stiff, no matter what alloy is used.
I used a chrome moly cage. I thought I was making the car lighter by stripping the interior but I was surprised by how light most of the interior is. I'm guessing there won't be much weight savings but at least it won't rip itself apart. 1-3/4" x .095 wall
I apologize if I am in the wrong discussion. Thank you for allowing me to join. Can anyone identify this for me? My husband passed and I was left with tons of mustang parts. I have done searches and came up with nothing. Thank you in advance.
It's been a long time since I've posted on The Corral, but find myself back after about 13 years.
Over the last several years, a few friends and I have been racing in an endurance road racing series. We started out with a 300ZX, and after a few years split off and formed another team running a...
I'm likely picking up a used long block within the next week and the oil pan it's coming with is the Moroso 20511. I'm sure it's an improvement over my stock pan. (I'd hope) Just want to verify among the turn'n crowd it's good to go as it's way easier to pull a pan on an engine stand than it is...
I bought a roller with the sway bar brackets cut off. Terrible... i know.
I want to fix this, and ordered sway bar bracket replacements from LMR a couple years ago.
How do I know what the stock location of the brackets was? Any tips on getting this back on?
