    Re: Why I'm not ordering a 718 GT4

    Thanks for the photo Weztcoaster.

    Looks similar to the 9A1, so would take a 981-style PDK. Noticed the Aluminum plenum and plastic oil sump. End of crankshaft looks different, too.

    Re: Why I'm not ordering a 718 GT4

    When photos of the new engine, flywheel side, are available, I want to see it.

    There are things that can reduce engine bay temperatures that will extend coil pack life. The GT4 scoops are one of the biggest. They significantly increase airflow into the engine bay, reducing...

  6. Re: Changing out brake pads and rotors at 40k. Normal for a DD with no track time?

    The front brakes do most of the work, so they can wear down first. Personally, 40K miles is good. Fortunately stock rotors and pads are reasonable.

    Re: Plummeting MPG?

    Porsche does make coil pack heat shields for 991s that can be added to 981s. Cost for parts is about $125. Four half shields and 8 screws.
