DSC Sport is proud to offer a fully active suspension setup for 997 and 996 cup cars! This is the same setup we used when we swept the Glen and set new qualifying and race lap records in the 2015 IMSA GT3 Cup Challenge. Check out the video below for some in car clips from the Glen.


And you can check out the full rain race from the Glen below, where we finished P5 overall, P1 in class!


As of now, our #36 car is the only cup car with the DSC Sport/Tractive DDA active suspension setup. However, we just shipped out our first, specially requested order for a 997 cup car.



The setup is now available for sale and includes a DSC module and a complete Tractive DDA coilover kit. For more information, call or email us!

 

What does a fully active suspension mean?

 

Computer controlled dampening.

Saw it at PRI last year. Looks very interesting. Good to hear that it is coming along.

What I would love to see with it is cockpit adjustability.

Thanks

Ed

 

Any specifics on Tractive hardware or DSC software features for the cup cars? How does the user select different maps from within the cockpit? Are the race cars limited to 3 software maps? Do the Tractive shocks have built in pots that Motec could log to facilitate suspension adjustment analysis?

 

I'm eager to try this on my car. Soon to report with findings...

 

Using CAN data, DSC Sport controls the damping value of each individual shock based on a variety of inputs, including vertical, lateral, and longitudinal G-force; brake pressure; accel pedal pressure; and steering angle in real time.

The system works the same for the cup cars as it does for the street cars, so you may find this discussion thread helpful:

There is an optional upgrade for the cup car system that allows for cockpit selectibility/adjustability. Here is a photo from Mike's #36 cup car. The **** on the left toggles between the three modes/maps. The **** on the right offers 10 different positions within each map. However, Mike has spent a lot of time tuning the off-the-shelf map you would be receiving, and it's unlikely that you would need any other maps. Also, bear in mind we will be releasing the software by years' end, so you can always create a custom map and load it onto the DSC via laptop/PC.

 

I also forgot to answer your question regarding datalogging/Motec. The DSC gathers Motec data, and we actually have a full CAN template for the Motec, which allows you to log all your suspension parameters.

 

The Good: these shocks are built like tanks.

The Bad: wiring harness, electronic and software aspects (being the key) all still in a very user unfriendly package. Zero documentation and has taken a LOONG time to come together.

I've stood by Mike and his guys on the DSC street product and know they're a good crew. But this... this is still a development product and NOT ready for retail consumption.

 

We're very sorry to hear that your experience with ordering your DSC/Tractive cup car setup has been anything short of exceptional. We'd like to point out that you requested your DSC/Tractive setup within a deadline, and we pooled all of our resources here to meet that deadline. In doing so, we forgot to include the instructions for the wiring, for which we apologize. Because our tuning software is not being publicly released at this time, we haven't yet streamlined the process of providing it to the customer upon purchase of a DSC. Our engineer made an unexpected trip out of town and is the only one who has access to the necessary files at the moment, which resulted in a delay there.

As always, DSC Sport comes with free tech and installation support. If you ever have any questions or need assistance with your DSC module or Tractive dampers you can call or email Tom, and he will be more than happy to help.

Again, we are very sorry for any inconveniences related to your purchase. Please let us know if there's anything we can do to remedy the situation.

 

Outside of specific set up, how do these units differ from the ones now offered for Vipers? Beat, Allan

 

Are these legal in cup spec classes? (i.e. GTC3)

 

All of the programming and valving for the Viper was derived from our Porsche system. Besides the obvious external fitment, the operating system and input to output protocol are identical.

It depends on your specific series. We are able to use it in the IMSA GT3 Cup Challenge on the 997 cars. The shocks are free in most series, but do check the rulebook for the specific series in question.

 

per pca 2015 rulebook:

GTC3 may use any 2-way adjustable shock.

GTC4 may use any adjustable shock. Remote reservoirs, if used, must be mounted without modification of any stock component.

So, real question for DSC... exactly what kind of shock is the Tractive damper? Can one argue that it's a rapidly adjustable 2-way? 3-way? 4-way? Multi-way?

 

Mike,

I have a new ACR on its way. Do you have anything that will work with it yet?

 

Hah, my Cool(ness) dial goes to 11.
