The 6t8 is equipped with VP&B dual mount suspension. I added the Dragvette 6-link to control inner axel movement. I had trouble with the rear overheating so I put a Derale cooler with a Tilton pump and XRP filter. doubling the amount of oil capacity. Seems to work, been that way over ten years now. T
Bringing this back to the top. I reached out to Hotchkis today and they replied that they hoping to release the C3 suspension system in August or September.

I am not fully versed in all of the engineering of the C4 rear suspension, but they went in the direction of 6 link essentially. Those could pull a G. I think the important part of making it work on the road course are the spherical/heim joints and what movement they give for tire track, the footprint. If you look at the old F1 suspensions, they evolved to having upper links, just what we are talking about. I don't think an 8 inches of travel is realistic in the world of racing. I go about 3 in. compression, and 1 in. In extension. I might shift that to 2-1/2 & 1-1/2 as I am pretty heavily sprung. I am still running wider 50 60 series sidewalls, not these modern aspect ratios. Have to finish talking later. Work interruption emergency.
I think the level of sophiscation and knowledge of other members will know where I am going, then I have to head out to a location to handle my work emergency, but the success of European designs and race car designs were based on unequal length upper and lower a-arms or links, whereas the design above gives you some heim/spherical threaded engagement, but nowhere near the designed in characteristics of other link or a-arm suspensions.
not to dig up a old ish thread but I agree on the 3 inches of travel if that I run 1600 pounds up front and 650 each in rear coil over set up and travel is very little sure as *** not 8 inches .
Got to go!
Does any body know what this does for your rear suspension and it's from Tom's it reminds me of the 6 link from racevette or dragvette .
Those are halfshaft loops (one on each side), it's a safety measure fore catastrophic failure of the U-joints/halfshfts. I'd suspect there is probably another on the driveshaft.
Note the NOTE!: "Upper adjuster must not be tight, it must be able to float back & forth!"
This says to me that it is only used after your half-shaft grenades, to keep the wheel in the wheel well and prevent additional damage to the car. So, not a suspension component at all.

That is a safety device in case the u-joint or axle breaks. The rod floats in the bracket, the TA have a bracket welded to it. The safety loops from Tom's are a lot better in my opinion. The Dragvette loop we had, broke at the weld when a joint failed, it is located at the outer end of the shaft. Tom's is on the center of the shaft.
That heim jointed rod would contain the rear tire (from tilting away toward the fenderlip) if a u-joint breaks.
It is in exact parallel to the half-shaft so it serves no geometry function.
The lower link and the half-shaft control the geometry.

FYI for all. When I reached out to Hotchkis in June they were shooting for an Aug/Sept release.
I reached out again last month. Here is the reply from 18 Oct:
"Thanks for the request, Steve, we are still in development. We have some final touches to finish up, stay tuned, we will be announcing when we are ready."
Feels like we are back in the COVID era of supply chain issues.

Sounds more like engineering redesign. Hopefully they took some of @leigh1322 's suggestions and will be releasing a much better product.
