Dundon is proud to be a dealer for the most revolutionary products for suspension tuning in recent memory. Porsche's® PASM system is good but it is a passive system meaning that when you hit the button it changes the shock settings and leaves them alone. The DSC controller dynamically controls the PASM system changing it to an active system. This is huge! It means that as the car is recieving data from the road/track the suspension settings can be modified in real time. The PASM system is good with 50ms reaction times to the controller. For those looking for more, check out the Tractive DDA dampers, these are world class dampers in their own right, but coupled with the Tractive valving the reaction times are reduced to 6ms. This allows for more sophisticated control parameters and less predictive based control as used on the stock PASM system. Take a look at the video for more info!
I'm very happy with it. In terms of affecting the cars outright performance, as such, I cant really say till I've been on the track, strip or Dyno with it - but Ill eat my hat if the car isn't measurably quicker in all situations. On a fast back road run for 150 miles it felts quicker for sure but in terms of lap times I don’t know how this will translate – Im thinking 4 tenths over a 1 minute track lap?. The DMS has given the car a different dimension and is one less reason not to rush out and upgrade to the next GT3....HIGHLY RECOMMENDED - Im a very satisfied customer! This is not a cheap product and infact the most money I have ever spent on an exhaust set up (and its only headers), for any of my cars ever. That being said its a quality 321SS unit that should last the life of the car, it is a direct fit for 991 GT3RS, 911R and likely the forthcoming 991.2 GT3, so there is a large secondary market if I should sell the car or I can take it with me to my next GT acquisition...and there is also a GT4 set for those who like to row their own gears on track!
Thanks Jamie & Charles for your excellent product, your excellent service and all your help in getting these to me. I look forward to your GT3/4/RS exhaust tips next! ~ Mark, Australia: 991 GT3 Race Headers
