Works in conjunction with the car's built in accelerometer to actively control the PASM suspension rebound/damping at each corner individually (versus all four corners being told to behave the same way) on any given road conditions.
Results in much more comfortable, less jarring ride on bad pavement streets in comfort mode and much more planted ride in Sport mode when driving aggressively with less squat and dive during hard accel and braking.
Got the chance to do the Owner Experience at the PEC LA this week. Was a total blast. Basically got to do all the regular courses one does in the drivers experience but instead of using their fleet cars we got to run the course in our own. Driving instructors instead of sitting shotgun would do instruction over the radio in their own chase/lead cars and they matched up cars in their fleets with the ones brought by customers, so 911 Turbo for 911 Turbo, GT3 for GT3, Carrera for Carrera, and etc...
Someone asked me my comparison thoughts between my Turbo and the GT3RS given they are a similar power/weight ratio
Both have similar power to weight ratios if you look purely at the numbers, but the power delivery couldn't be more different. The true definition of linear vs turbocharged power delivery.
GT3RS: with its 9000 RPM redline and weighing around 300 lbs less than my Turbo (7200 RPM redline, its power delivery feels even more furious than my car when you rev it to redline. And my friend ditched the stock RS exhaust with an Akrapovic piece making it sound even more insane.
Basically, its a totally different visceral driving experience where its way more thrilling to drive at 8/10ths and above, and the linear power delivery is a more 'honest' feel than the Turbo. In my Turbo, its not seamless spooling of the turbos and you can feel when they kick in and at that point there is a brain disconnect between how far I push the throttle and how much acceleration is being produced, so its easy to go way faster than you realize. The only disconnect that is even more extreme is a powerful EV like a Tesla in Ludicrous mode for example.
With the N/A GT3 motor, I don't have this disconnect, wherever I press the throttle, the power delivery is where I expect it to be and makes sense, and I miss that direct feel in my Cayman (altho that had way less power and poor gearing).
Handling on the GT3RS of course, especially on twisties, there is not comparison, but I left traction control on in the mountains and it was still easy to drive at the pace I chose to (not being my car and being RWD with constant fear of stuffing it if I exceeded my talent limits).
So when driving HARD, the GT3RS is a much more fun experience, but anything less than that, it loses its charm and can become very tiring after prolonged seat time especially for this old man.
To use an analogy, if the Turbo and the GT3RS were two different friends:
The Turbo - that friend who can be the life of the party and switch it on when he needs to, but can also dial it back and be chill when you need that.
The GT3RS - that friend who is even more of a party rager than the Turbo and does nothing less than 10/10ths, but when the party is over, has no idea how to turn it off and becomes annoying AF in any other situation. When you're not in the mood to have fun, you want him to GTFO out of your house lol.
