Yes, I just visited Vansteel yesterday about updating my 64 Corvette suspension. They showed me the 8 link display. They have plans to run some rigorous track testing, they need to make sure the geometry is right. Not sure on the time frame of when they will release item.

Anyone care to guess how much this will cost?
I wonder if it will be a bolt on, or major fabrication?

Of the 4 inboard links 2 mount in factory locations (strut rod and half shaft) while the other 2 mount to a bracket that’s mounted to back of the diff. 4 outer we’re similar, strut rod, halfshaft then 2 mounted to brackets on trailing arm.
It must have modified trailing arms with a pivot or joint in them does it? Other wise surely it would bind, unless the links follow the trailing arm arc, in which case it wouldn't change the bumpsteer that I imagine the extra link is intended to solve?

Probably Johnny joints is my guess. They offer those in their offset trailing arms.

That won't really help - I have Johnny type joints in my Global West trailing arms too. You need an additional pivot point further towards the hub in the arm (or to leave out all the shims and let the arm move back and forth on the bolt!) or it will bind. Either that, or you place all the links to mimic the trailing arm geometry, in which case you don't fix the bumpsteer, and the rearmost link would seem redundant.

The owner specifically mentioned the inherent snap oversteer of the stock system and that this was designed to prevent/minimize it. Maybe @van steel can comment?
DRAGVETTE.
As you can see in this photo the Dragvette kit comes with inner [not installed] and outer half shaft loops.
This photo barely shows the upper link which is bolted to a bracket mounted to the top of differential. This type of rear suspension an a C3 does not allow any camber change and it also does not correct wheel hop. I have had this kit installed and have hundred of road track hours on my setup with very favorable results. Price at time of purchased was under $900. T
The upper link can replace the half shaft as a suspension link if the upper pivots line up with the center of the u joints and and lower pivots (drawing a line through them. This reduces/eliminates the amount of half shaft in and out movement. There is always some play in the half shaft.
Unless the T arm has another pivot point allowing for a hinge effect at the spindle you still have the toe change issue found in the stock T arm system. Have a pivot only at the front does not address this.
I do like the design as it does remove the half shaft as a true suspension link.
Agree 100%. If you look at the picture above, there appears to be a second lower link, (just visible behind the upper link). This would presumably be a toe link, but as we said, will not fix the inherent bump steer issue with the c3 trailing arm suspension unless the trailing arm has an extra pivot.
I am having some halfshafts built with a slip joint at the moment so that I can add an upper link and change the geometry if desired, while taking the suspension loads off the halfshaft and diff.

Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
