When the PDK in Sports Plus shifts close to redline the thing really kicks ya in the back and the car just surges forward...it feels like you are riding a wild animal. I drove the Cayman R in manual...wonderful transmission and I enjoyed it, but to me with a car like this, the PDK was the only choice for me and it matches the incredible performance of the car.
I absolutely love this transmission...95% of my cars were manuals before this...my trucks/SUV were automatics and I had one Lexus IS300 with "tiptronic" and I absolutely hated that transmission, it was so dull and slow I just left it in auto mode and eventually it became my wife's car. Currently I have 2 manual cars right now, an M5 and a 325 and an automatic X5. I drive the 325 often (M5 sometimes) in the bay area so I have no problem with driving a manual in traffic...and I drive 40,000 miles a year back and forth between Modesto and San Jose for my various construction projects.
Every time I take my M5 out into the foothills, I always wish I had my PDK in that car and really any manual car I've driven since. I like the manual when I'm just tooling around and driving casually or even some more spirited driving...but the PDK is just so glorious to drive at the edge of the envelop (mostly mine) and to pop the gears down as I enter the corner...hear the FFFFFBAM sound at every gear change, and the kick in my back and snap of my neck when the PDK is racking the gears up close to redline. The 981 is about razor sharp performance in a fast, light-weight package with moderate horsepower...and I think the PDK takes all of the various separate parts and interconnects them into a cohesive and complete package...much more than a manual.
