As we all know not much info about the car, but has been published that Multimatics DSSV damper technology is in the race car, and I assume the street car also. This technology has been used in a camaro, and now in this new Chevy, "ranger raptor", just announced at LA auto show. The GT of course won't use the 3rd stage spool valves like the off road damper, but still a good explanation of the technology. Pretty cool, so to all my fellow tech heads that enjoy this kind of stuff.....

The interviewer has mic issues (can't keep it even distances from people yielding volume differences), and is clearly live, with out editing.

Mr White from Multimatic does a good job explaining the technology. The interesting bit begins at 8:30, and sorry it's about a GM product.

Interesting info. Larry Holt was proud to talk about the DSSV system at Daytona. I think that's his baby.
We were having a discussion about active suspension systems on the GT .
I brought up magnetic ride control . I was not familiar with the Multimatic DSSV Technology . He confidently said with a smile something to the effect that like 50 of the top race teams around the world use DSSV shock systems.. It will be a good fit on the GT.. .. I trust he knows what's best !! :biggrin

Interesting technical overview, thanks for sharing Andy.

I can certainly see the potential of the design. Must be a huge amount of simulation to arrive at the initial/proper combination of port window shapes ~ valving), shock oil, spring rates to arrive at a solution that can operate consistently in all of the specified operating parameters.
 
To date it GM has used both magnetic ride control and the Multimatic DSSV and so has Ford. I think it's safe to say the DSSV system is the " Cadillac " or should I say " Lincoln" of shock absorber systems .. :biggrin. It's great to see these technologies migrate through the product lines..
 
Now we just need to wait til such a system is offered to us old FGT owners ...
 
You know I will be picking the brains of our friends about this.

According to the video, the Magnaride doesn't deal with heat well, especially in an off road environment. There is also the weight side, Magnaride is heavy compared to a traditional damper (the additional electronics).

Make sure you share the info.
 
No perfect system out there, it's weighting the pro's and con's

Well DSSVs are used in championship-winning Formula 1, LMP1, LMP2, FIA GT, GT3, etc... cars. So I guess they must be good.

By starting out with the " Well " statement I guess you didn't get the point of my post.. please read the last line of my post.. :biggrin

Another decent quick article on DSSV

Certainly an interesting technology. I wonder what differences are employed in a traditional spring/shock assembly vs. torsion bar/shock assembly?
 
Also with the adaptability of 50mm ride height change. Would like to see the cut away showing how the electronic adjustment.
