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
Im looking at these Global West front control arms. Anyone running these? I initially wanted tubular front control arms for wheel clearance on my 1990 gt. Im flip flopping between these and the BMR ca's. These ones are a little different though, the sway bar end links are attached to the arm? Im...
MM torque arm
Ford Racing Aluminum Drive Line
Finished installing my MM torque arm MMTA-1. I have set the pinion angle to match the angle at the crank pulley while at ride height. I also have fresh gear oil in the diff as I had to rework my cover.
I took the car out out for the...
Decided to order one Enkei RPF1 in 17x10 just to test fit. The common belief is that Mustangs with Cobra R brakes (Brembo 13 inch kit) do not clear those. Well, I'm happy to report that they do in fact clear the wheels, and the suspension. It does stick out just a tiny little bit in the front...

So I came across a set of GT500 6-piston front calipers and 15" rotors for sale locally and the price was so good I couldn't pass them up. When I went to pick them up I saw why they were such a good price. The fellow who was selling them had attempted to sand off the factory red and then spray...
