I've been reading a bit about this lately.

DSC Sport

It's available for 996, 987 1 & 2, 997 1 & 2 and 981 or 991. The 9x7.1 cars need a separate 3 axis accelerometer because the factory unit is only 2 axis (except turbos and GT3, I think which came with 3 axis). It's also avialable for Vipers.

If your car has PASM, then it's a direct swap of controller (with 987.1 and 997.1 cars requiring the additional 3 axis accel that comes with it). It works with the Bilstein Damptronics too. If your car didn't come with PASM, but there is a stand alone option. They also have a version that comes with high end aftermarket shocks that are more advanced than the Bilsteins.

As I began reading, I wondered how this box could be an improvement over the Porsche setup. This box talks about stiffening the front upon braking, the back on acceleration and the outside on cornering. But then the stock PASM controller is supposed to do all of that. Eventually reading though a long thread on RL, I found their explanation about how/why their box offers improvement. Apparently, the stock PASM setup uses a very limited portion of the stock shocks range while the DSC box uses much more of the range.



Here's a quote from a post by DSC on the RL forums.

Tractive DDA shocks bring racing level performance to a street car only when the driver needs or wants this level of stiffness. For street, the supple and controlled ride is a result of maximizing shock stroke paired with more stable springs and superior electronic management that will soften the "nose" of road bumps and stabilize the vehicle against oscillations before it happens. The dynamic range between street comfort and race track performance is made even more flexible to the individual user preference with the tunable software that we will release later this year. The standard mapping is already very well developed but you can personalize it for your exact usage, preference, and your local roads. A way to depict the dynamic range of Tractive DDA is to think of the PASM modes as "3" for Normal and "8" for Sport. The "3" and "8" are pretty much fixed values. With DSC and OEM PASM shocks you have a dynamic range varying between "1" to "10" based on the speed and other inputs for the driving situation. Tractive DDA's range is "-5 to 15". In addition to the much wider range there is no "bump rubber effect" and the reaction time to command is 17x faster than OEM PASM to shape damping curve to stabilize vehicle oscillation; soften nose of the compression then ramp up as load increases and tailor rebound to smoothen vehicle weight transfer, which results in reduction of shocking to tire contact patch, which results in more grip.

I have to say, I'm curious. Most of the postings that I've found on various forums on the 'Net are from folks that think this is a huge improvement over stock.

Apparently, as a customer, you also get access to the software that allows you to custom program the shocks if you want, and you can upload maps and share them with other users. I think the maps should to be shared among similar car layout vehicles, IE, 911<>911 and boxster<>cayman.
