Thanks Tom. It's been a pleasure discussing this stuff with you. I don't mean to be an armchair quarterback expressing premature opinion, which i'm sure I am.
I look forward to driving more and thank you for mentioning the other available files. It's very cool stuff. The roads are pretty bad by me so I think the normal mode could be a good thing.
I do have the Porsche space saver spare in the frunk, which is pretty darn heavy. It makes the ride feel a little better with the stock suspension for some reason but might not be ideal for the DSC driven suspension. Regardless It's a really cool product you're offering. Thanks again. -Chris

I also used to run these low pressures at first, until I got to a Porsche Experience training (my third one now) where the tech explained that the chassis is designed to operate with super hard tires so it can control all the rest.

Have a try at some street driving with cold pressures set to F35 R45 and see how the car feels after a few days.

If you drive hard, remember, this car is build for late braking (more than an M3) that's when you really feel like you can quickly pivot it at the apex and punch out.

After getting acquainted with your new chassis, let me know you find it to understeer too much, just right for your taste and or you always loose the rear and can help you with further adjustments.

Obviously, these pressures would not work for the track because you'd build and maintain much more internal heat so I suggest we keep track talk out of this conversation.

Don't knock it til you tried it.

Wow, 35/45 cold seems really high, but I will give some higher pressures a go. Did some more driving this morning with the weight (spare) out of the frunk which I think helps. Also I ran in sport suspension the whole time which seems like the only mode you need with the DSC. After only two sessions of driving I'd say the car feels closer to a GT suspension, in that GT balance of aggressive fused with compliance. I've often thought the GT cars ride smoother and soak up bump better than their Carrera siblings. I still need to get used to the slightly more progressive feel of the suspension loading up, but I think I will. Really cool stuff to be able to feel such changes while not changing mechanical suspension components.

ZerOG

Yep, I really didn’t want to try that either but when I was handed a car setup that way, I realized that I had to try it on mine. And it worked. i also suddenly hated my P-Zeros a little less. I still changed them for PS4S though.

My next upgrade is the KW HAS coilovers. Since the ratio between the front and rear spring rates are going to be completely different (ratio gap makes a bigger difference than spring rate itself) so I will have to start from scratch to RE-balance the car.

The question is - Would you buy it again? Is it worth the money?

Ceepe

If it was hard to access in the vehicle, or overwrote information as an ECU tune does, it might be a tougher call. Factoring the location of the controller on the 991, how seamless the product inserts, and the parameters and capability it unlocks or better exploits, it's certainly a worthy modification to explore. Assuming one feels suspension limitations and wants to explore changes. I've only driven the car twice since installing it, but I think it's already impressive and would likely buy it again. Tom is also very helpful. I had a question after my first drive with the product, Tom picked up on the first ring and answered the question. Good operation, good support.

Nice. This just moved up to the list of To-Get over Soul Sports Cat once tax season is over.

For me, after having done a few mods over the winter, Numeric Short Shift Kit>Soul hi flow cats>Cobb>Kline headers>DSC

DSC last place of the mods

Interesting. The T luckily have a short shifter already. I was debating between Soul Sports cat vs DSC but I think stock PSE is pretty decent already. Would love the car the handle a bit tigher in the backroad.

Tom@TPC Racing

Awesome! I imagine the weight of the spare tire is like 40 lb. Which is close to the weight of another half tank of gas at the nose of the car.

How does this react to progressive springs?

Tom@TPC Racing

Short answer is DSC Sport V3 controller pairs very well with progressive springs. Most OEM springs are progressive.

The longer answer is DSC Sport V3 controller varies the damping commands to each damper to the driver's input to optimize vehicle weight transfer regardless of the type of spring on the car(progressive-rate coil springs, linear-rate coil springs, and even leaf springs!), as long as the spring rate is within the operating window of the dampers, which all OEM springs are.

Tom does this mean it's possible to map GT3 "Tour" to DSC Normal, and GT3/RS to DSC Sport?

ZerOG

If you’re looking for real GT3 handling, I have the full OEM coil-overs from a GT3RS or a GT2RS and they’ll also work with the DSC but the spring rates are for serious track use.

Tom@TPC Racing

That is exactly what the DSC GT3 "Tour" calibration file already is! Softer in Normal mode, track optimized in Sport mode! I made this file because that's what I'd want if I own a 991.
