Hello,

2017 Carrera 2S, with the 10mm lowered factory option. 18 months left on CPO. Suspension 100% factory stock.
I usually roll with comfort tire pressure settings.

Don’t get me wrong, I like a firm ride. I’ve owned an 80s c4 Corvette that had the factory option for bricks instead of leaf springs.
The 991.2 is something else though.

I usually ride around with chassis in sport mode. I find the jittery/bumpy nature of normal chassis mode to be more unpleasant.
On bridges I frequent with expansion joints, I can only describe what the car is doing as twerking.

I was watching videos about DSC and the impression I get is it smooths out the jumping and bouncing and chattering around town quite well.

I never track the car. I’m about 80% city/town driving, and 20% mountain roads.

Do you think this would be a good application for my 991.2 C2S?

Ideally, I want to extend the service life of my internal organs as well as convince my wife to actually ride in the car sometimes.

 

Get it. You wont regret it. It will solve the problems you are having. Smoother when cruising and firmer when pushing it. It provides a great balance and you can also change it to better fit you if you dont like the supplied programs.

 

Thanks! sounds like I’d better get on the backorder list ASAP then.

 

I've had it on my 991.2 GTS for the past 2 1/2 years and it is fantastic.

 

I had the exact same issue as you describe. In normal mode, the car would bounce up and down after every big bump, but sport was too harsh for daily driving on California roads. My only issue with it is that now the difference between normal and sport suspension is less dramatic.

 

I have a 991.2 C2S. I also have Eibach lowering springs. The DSC is a no brainer. The thing you need to understand about it is that the differences are felt most under harder driving such as acceleration, braking, and cornering at speed. You will not notice any major differences under ordinary leisurely daily cruising unless you are always driving like a bat out of hell. But the ride is definitely improved overall. Just not super noticeable until you really push the car.

DSC is a must.

I got paced by a honda civic through a corner on the softest setting which is kinda disappointing lol. I'm a base C2 so the springs are very soft and the suspension just deflects and understeers.
With the DSC you can feel it soften/stiffen so it's not very smooth but I assume with tractives it might be smoother. One thing I do miss is the stiff mode seems to provide more feel in the steering and chassis overall, but the good thing is you can set that through the software.

It doesn't change anything at the limit, but it makes it more comfortable. Turn in, braking, and accelerating is soo much nicer. I also ordered Bilstein B16 coilovers but they have a 8-16 week backlog So probably won't get it till later this year. I found the suspension was just inadequate. The bilstein offers best of both worlds with a progressive spring rate so it's probably more comfortable. We'll see!

 

thats alarming.
also surprising it has to be sent in to be reset.

ill have to ask them about the overheating issues.

 

@itbme Love the DSC!

It does exactly what you say in that it keeps the chassis more settled by smoothing out the jolts on rough pavement, and stiffening up when called for on smoother roads. I've had one in 4 different cars over the last 8 years with never a problem.

 

Keep in mind that every manufacturer has a bad unit go out every once and a while. Ask the question for sure but from my personal experience, one in my Carrera T for going on 5 years and one in my GT3 for almost 3 years, the units have been flawless.

 

read about the one failure out of thousands sold! Whoopty doo. If you want to get one, keep the stock controller, and if you have a problem it can be swapped in 10 minutes. Certainly nothing to worry about unless it actually happens, which statistically it won’t.

 

swap the factory controller back in and drive around, it’s pretty noticeable the difference even in normal driving conditions. I think it’s easy to get used to the DSC and not notice how different it is from OEM.

 

Hate to disagree but it's not one failure. There are a # of people in that thread with failures.

Not sure why everyone with a working DSC controller seems so defensive of a company that potentially has a quality issue with their product. I understand folks like the product, but there are 2 people in a local Facebook group (pacific NW) who have 991's who have failed DSC controllers. Same thing. And then those who are posting about it on Rennlist. That's not random, or "one failure out of thousands sold".

PS I am rooting for the company and wish the product was great. I have no interest in talking smack about what was previously thought to be an A+ product.

 

TPC Racing/DSC Sport is one of the most highly-regarded Porsche racing and modification shops in the US. They've been around since the late 1980's when Mike Levitas started the TPC Racing team in Porsches. As a driver, Mike won the 2006 Rolex 24 Hours of Daytona GT Class, and he has won many Porsche Cup Championships.

In 2023, they built and opened a new mega shop. Their primary business is preparing Porsche race cars for IMSA and Porsche Cup classes. Mike also became a leading expert on chassis setup for max handling, and they maintain a close relationship with Porsche engineering. To this day, Mike travels extensively to work with Porsche on track testing.

I live 40 miles away from their shop, I know Mike and Tom pretty well, and have had many discussions with them on the DSC topic. They've sold 10s of thousands of DSC controllers, and they have very few problems with reliability.
