Now stock vs. stock, the 991.2 GT3 RS is not as street friendly as the 991.1.

Front went 222% stiffer, rear 33%, no idea where that 60% is coming from.
Do you know if the FAL bug has bee resolved?

Also what is the difference between your street and rain maps?

I'm getting curious about a DSC in my 18 GT3.

Curious to learn your process to update the mapping based on conditions.

It's not too stiff to be uncomfortable. In fact, many less sporty cars are less comfortable - for example, my 991.1 GT3 was definitely more comfortable than my friend's AMG c63. And I daily-drove it in California, which is as bad as it gets in terms of road quality. The .2 RS is stiffer, but not by as much spring rate difference may imply. That stiffness is unnecessary for road driving performance, but not too uncomfortable.

3RS is stiff but not harsh. AMG GT, C63, New Vantage, etc these cars are real harsh.

Get a non-RS if you have to talk about ride being hard. Seriously. Move.

No - works well and at speed is way less fidgety than the Series 1. Slightly softer anti roll bars too - works well.

I find it stiff, but well controlled. There is a lot of road noise compared to other cars, but I don’t mind it.

Not as stiff as the 997 GT3 RS.

there is good stiffness and less good stiffness 😀👍

the stiffened spring rates are balanced by great dampening and pliant roll / smart engineering 😀

I have FAL, no problem with my DSC and it has been there for months.

I can't post a detailed training on how the PASM shocks work and how they interact with the DSC software, it would take days of writing and get more questions than answers. The DSC software treats these shocks as 4-way adjustable (Low and High speed compression and rebound). The rain map has much softer compression and rebound than a stock 991.2 Carrera S, the street map uses the voltage range of the 991.2 GT3 reduced by a percentage.

At any time you have two maps available (using the PASM button). For street driving, Comfort has the normal street map, and Sport has the rain map.

For track driving, I have a rain soft and rain super soft map, I have a bumpy tracks soft and medium, and I have a smooth tracks hard and super hard.

6ft long USB cable and a small laptop to switch maps. Countless hours of tuning and 2 drivers providing inputs.

I would like a wireless mini-usb adapter that could connect via Bluetooth to the MS Surface, so I could upload maps from outside the car. Uploading a map takes about 2 minutes.

It’s much better on track, no question about it.
But when not on track, I keep looking down wondering if I pushed the PASM button by accident.

The .1RS was much more compromised on track but was quieter and much softer.
But the .2RS except for the worst roads and I’ve had bmw’s that were more uncomfortable.

So in technical speak, squishier and slower for your rain map. Thanks for the details.

Wish there was a demo program for the DSC, pay one way shipping, put down a CC as deposit and ship/install the unit for testing. Or I need to find somebody in the Bay Area willing to loan.

I messaged Tom at DSC, and he said they still haven't sorted out the fault message on cars with FAL. It was supposed to be finished in June but haven't heard from him in the last couple of weeks.
