Love mine too. Have it installed for over 6 months now. Just a better overall ride.

That's awesome, me too. I thought it was surely placebo noticing it so immediately, but it wasn't.

Dumb question, but what's the downside of the DSC? Why didn't porsche set up the car this way from the factory? Based on comments, the normal setting isn't harsher than stock, so there's no downside there. And in sport, the performance is better as well.

Good question, my guess would be the same reasons there are always aftermarket improvements to many OEM things – cost, maintenance, regulations, or they just haven't implemented this technology (whereas DSC is presumably an expert in this specific area).

Do other 911 platforms have anything like this (like the GT cars)?

Increased wear on the hardware components, I reckon. I'd love to see quantifiable data that this $1300 gadget makes your existing hardware objectively 'better' than it already is.

It doesn't make it "better", it utilizes what's already there in a different manner. To simplify it, it's like tuning your suspension like you tune your engine for more power or sharper response etc.

From what I'm hearing, it sounds like the damping is being extended beyond the stock parameters -- very similar to how one would tune an engine for more power, using your analogy. If true, this would increase wear as more of the suspension travel is used more often. No such thing as a free lunch.

I too think the DSC is a game-changer. I added it to my GT3 Touring about a year ago. Just today, I bought one for my GTS as well. To me, after driving in the GT3 with the DSC, the GTS suspension in both normal and sport mode is too bouncy and mushy. Although the GTS will never "feel" just like a GT3 (for numerous reasons), adding the DSC will allow me to customize the suspension to taste, rather than having to live with the factory settings forever. Two thumbs up!

I think engine tuning isn't the best analogy, since that pushes things outside factory params.

But, from DSC's FAQ: https://www.dscsport.com/frequently-asked-questions/
Will DSC Cause My Suspension To Wear Out Faster?
No, DSC Sport does not add any stress to the factory dampers or other suspension components. In fact, the factory control method sends a constant current to the dampers, while DSC Sport alters the current and utilizes a series of on/off commands. Under normal usage, DSC Sport will ultimately send less current to the dampers allowing for better cooling during usage.

So they've managed to improve what Porsche engineers developed, within the confines of the hardware as provided by factory, while also implying they're reducing wear.

Interesting.

warranty and a loaner I get to use as a punching bag takes care of that

From what I've gathered, the main advantage is the controller is able to individually adjust each damper (whereas PASM just adjusts them all together), using more data and providing a broader range of adjustment. The algorithm driving it all comes from years of race data, so I assume there's some special sauce there.

In any case, I love it, and I'm not at all worried about any adverse effects to the dampers.

SPASM in the 991.2 is 20mm lower than cars with PASM, at least that is what my window sticker says.

forbiddenbeat

I believe PASM is 10mm lower than base, SPASM is another 10mm lower.

Add me to the list of very satisfied customers and fanboys of the DSC Controller. Also, a shout out to Tom at DSC, I had a couple of questions regarding the software and he patently answered my newbie questions.

To really understand what the DSC is doing and how it's doing it I strongly suggest viewing the main Technical setup video that is on the DCS website and on YouTube. It's a tutorial on how to make adjustments to the DCS via the DCS tuning software but it also shows the concept and thought process behind why the DCS can do suspension setup better than the factory Porsche setup. This is not a criticism of Porsche, quite the contrary, after gaining a bit of knowledge on how to tune the Porsche suspension, I have a greater appreciation of the work Porsche engineers had to do to make a 911X feel like it should to the average Porsche buyer. The Porsche controller is doing the same functionality as the DSC controller just in a more static manner without the ability of the end user to make their own adjustments.

One of the main reasons I wanted to purchase a DSC controller was to get a bit of a more compliant ride in normal mode. I live in Northern California and the roads from freeways to canyon drive roads are in rough shape. Freeways are mainly concrete so the seams between the slabs have heaved over time and the concrete has worn due to traffic and has waves worn in that are affectionally know as freeway hop. The secondary roads tend to have smallish ripples and swales in them due to the type of sandstone soil we have plus minor earthquake activity, combine that with poor maintenance and you have roads that while fun to drive will challenge any suspension. Last week I went on a 40 mile ride over some of my favorite roads with the GT Touring setup that comes with the DSC as my baseline. From freeway to canyon roads it was a significant improvement out of the box. However, I was curious if I could make the the ride quality even better, so I downloaded the DSC Tuning software and started experimenting. After a few days of trial and adjustment of normal mode, my butt dyno told me I have gotten my TTS to have a notably better ride than my Audi sedan. To be fair, the setup does have a bit of softness and bit of floaty body motion when the car is pushed hard above the speed limit on secondary roads. That said, I hit my goal of a very compliant ride when on the freeway or just cruising along with traffic on secondary roads.

That's great but I don't want a softer ride, it doesn't feel buttoned down like a Porsche should..... This is why God and Porsche gave us the Sport button. Again, the GT Sport Touring file is very good but I've started to make some changes that takes me closer to a GT3 RS setting in Sport mode. I'm still experimenting here but bottom-line I've widened the gap between the Normal and Sport modes.

Again, hats off to the folks at DSC. This is an amazing product that will provide more bang for the buck performance improvements over any other modifications for your Porsche.
