Global West - new aluminum spindles?

Global West has a notice on their home page that they are coming out with forged aluminum spindles that are 1" drop and that the spindle will correct geometry...
This will be interesting to see how it turns out....

Wonder why on the choice of Alum vs iron? Call me old skool but I would feel better at 70+ with bumps and pot holes(or wheelies!) with iron not Alum.
I'll let someone else go first!!

I am sure the pin is steel.
Corvettes have has aluminum spindle uprights for a while.

That idea has been kicking around for awhile there.
As Jsams indicated, the Corvette has had them for awhile. The original vette
platform that had them (C4?) and the sealed wheel bearing hubs is about the
time period they started contemplating aluminum spindles.
We didn't intend on "pins" on the hand-fabbed 67-69 Camaro aluminum spindles
we tried in the mid-90's, they used the vette sealed hubs- looks to me from
the photo that the new GW aluminum spindles will have steel pins no matter the
designed application. (The 1st gen Camaro Negative Roll system, as it turned
out, didn't require the taller hand-fabbed aluminum spindles, so the idea was
shelved just prior to my departure from there)

To reduce unsprung weight, helping to get a better handling car. Aluminum spindles have been common on high end road cars for decades. On real race cars they were used much earlier.
To day a modern family car like the VW Passat, have the spindle and all the control arms made in aluminium. VW started using aluminium control arms in the front suspensions back in the 90s.

I think another reason is ease of manufacturing, for a low volume part, it will be cheaper to CNC Aluminum billet vs. the investment in a steel casting/forging or fabricated steel.

I do wonder how much such spindle will hurt your wallet...

Other than the drop, I am not sure what the gain would be for a old mustang.

Someone said unsprung weight, but I would like to see the actual weight of this aluminium spindle and a standard one, for comparison.

Potentially stronger than a stock spindle too, but I am afraid of the cost more than anything.

Another advantage is in changing the spindle overall height. I guarantee you that
whatever amount it is, it's not a stock dimension.

I didn't think of that...A taller spindle can have a better camber curve.

Depending on the spindle length the 1" drop {or raised pin) could possibly create more wheel clearence at the upper ball joint. That would open up more choices in wheel widths and backspace.

I DON'T see a negative. I hope its taller and variable heights would be awesome. I run Al spindles on my GM A body and have hoped this would eventually make it over to our camp someday. I look forward to it with great anticipation. SOT with GW Al spindles sounds like a Cortex competitor on a budget
