me, Tw00si had it before anyone else and I think someone else that pbp instructed as well

We have at least two people running them at the VIR track day later this month.

I should be there as well

Appreciate everyone's quick replies! What's cool is that once I install it I can just switch the harness from SDI to DSC, so I just need to get off my butt and do that. I'm glad everyone's feedback has been positive!

I did like how DSC was reaching out to customers asking which Springs they are running, and giving presets based on that setup.

@optronix both systems adjust dynamically, apologies if I didn't explain that clearly. I can definitely feel the system working underneath me, as all four dampers independently adjust themselves with throttle, braking, and steering inputs.

@timestamped so far, there's me + 6 others that we've sold to. We know SDI has sold them more than us. Here's the setups I know so far:
- SDI + stock springs FL5
- SDI + Swift springs FL5
- SDI + H&R springs FL5 (me)
- SDI + stock springs DE5
- SDI + H&R springs DE5
- SDI + RSR Coils DE5
- SDI + RSR Coils FL5 @nojeebs

I know two of the DE5 owners are on Integra Forums. I've tagged Justin above so he can share his thoughts on his RSR + SDI, but give him a bit as he just installed it yesterday, so he can only really comment about install

Yeah... it's important to note that the DSC is just simply a more sophisticated unit. It adjusts dynamically; no need to adjust "on the fly", it adjusts for you dynamically while you're actively driving.

Full disclosure; I live near DSC and had them install the unit and use my car as the basis for the OTS base map for a car lowered on springs. I received a promotional discount but it was the same one everyone received for being an early adopter lol (i.e., I paid $800- it was not given to me to provide a favorable testimonial).

For those unaware, you can provide details of your current suspension during checkout that establishes what base map your unit arrives programmed with, although you can of course tune/adjust it to suit your individual preferences. All you need is a laptop and the free software. But to my experience that has not been necessary.

I have had an opportunity finally to evaluate it while driving in anger during autocross. It just responds to inputs exactly as advertised, it's kind of a magical phenomenon to experience in action. The car felt like it had infinite grip and sacrificed no rotation at all- no adjustment needed. I'm running the base map the unit came with (that in fairness was tuned on my car- but it's the same map anyone would get if they explain that they have a car lowered on springs).

Agree with the overall comments. I just spent 4 hrs attacking the mtns of NC/ TN including the Tail of The Dragon along with a Ruf 911 TURBO and a 911R. The DSC (OTS) allowed me to outcorner these cars on the twisty roads and made me smile. The other drivers were amazed at how controlled the car was, especially in the extremely tight hairpin turns on the Dragon. Depending on the section of road, I was mostly in +R mode or Individual Mode with everything dialed up to max except the suspension was in "comfort" position for the really tight stuff. ( 2025 CTR w/stock suspension/wheels/tires, a modest tune and PRL rear motor mount).

My initial reaction to the DSC was that it trade-off the urgency of the steering turn-in with the stock suspension but improved ride, handling, and grip. Over-time I have shifted my concerns over diminished turn-in feel and embraced the overall advancement in handling dynamics.

I have around 1500 miles with DSC unit and absolutely love it.
Granted my FL5 is a daily driver + occasional spirited drive through some curvy roads.
Stock suspension depends on the mood I drive in all 3 mods without any issues.

Awesome feedback…definitely making me look forward to installing my DSC and testing it out for myself with all of these positive experiences.

I’m on a stock suspension and want to keep it that way for the most part. The DSC sounds like the perfect upgrade to give a slight edge in performance.

Keep the updates coming!

I have one and love it, but don't have enough miles on it to formulate any opinions on how one might program it to improve it. It is a major improvement in daily driving.

I'm on stock springs.

I keep the DSC in comfort mode, since it will automagically firm up as needed all the way up to +R firmness.

based on my research (not my own testing/gut feeling)

Mode	OEM FL5	OEM DE5	DSC (FL5 calibration)
Comfort	0–35 %	0–30 %	0–100 %
Sport	25–70 %	20–60 %	20–100 %
+R	75–100 %	65–95 %	50–100 %

below diagram seems to be for DE5 (terminology track vs +R and highest damping at about 95%)

Our Dynamic Suspension Controller replaces your factory suspension control module to gain full control of your factory shocks. The DSC uses an advanced active control strategy that responds to conditions to command stiffness of the shocks in real time. Additionally, the DSC uses the full operating range of the shocks where the factory controller uses only a fraction.

+1 DSC sport controller installed

Initial response is that the bump absorption and ride quality improvement in Comfort is quite good.

still corners flat, feels more laid back but still light on its feet. Will be exploring sport and +R

Add another to the list.

I'm an indie Porsche mechanic by trade so I've heard a lot of good things about these modules on 911s and Caymans. Ordered one for myself the second i found out they made one for the CTR. My autoX season is coming up in July and we run on a pretty bumpy lot so it'll be interesting to see how this changes performance.

Update on my DSC experience. I've now done Road Atlanta, NCM Motorsports Park, Nashville Super Speedway, and Ozarks International Raceway over the last ~6 months, and I'm incredibly happy with the controller.

I finally started doing some tweaking to the OTS mapping, using the traditional bump/rebound inputs as a way to tweak the balance and had a ton of success. Using Sport as the base, I added some front/rear rebound and the car rotates very nicely now on entry and I was able to dial out a lot of mid-corner push.

The fact that it's also incredibly comfortable on drives to/from the track is a huge bonus. I'm still very impressed with the module and can't recommend it enough.

Ozarks especially has a ton of weight transfer, bumps, and hills and the car was an absolute joy there. Here's a lap for reference:

Awesome feedback. Can you share what adjustments you made exactly?

Also, what camera and mount/assembly are you using? - Great video quality and angle.

I went +5% on front rebound and +7% on rear. As long as you're smooth on the brakes the car has nice entry rotation and minimal mid-corner push.

The camera is a GoPro Hero 10 Black and I've just got a gorilla pod wrapped around the passenger seat. It's a little bouncier than I would like but until I can get a 3D printed solution it works well enough.

Not my photo but it's basically this:

Nice setup. Thank you for sharing!

Would you guys say its more comfortable on street versus the ITS module?
