    Anyone local in the Metro Atlanta Area have a ACPT driveshaft in their STi? If you do, please share your experience. Kind of intersted how it really is since I read so much about it on IWSTI.com, thank you.

    sincerely

    +1 on this.....

    There seems to be a lot of hype over there about this thing.

    It should pretty much feel like a lightweight flyweheel and pulleys no?

    actually no... it should feel more like light wheels

    a lighter driveshaft will not reduce the rotational inertia of the crank (like pulleys and flywheels do)... it will reduce the rotational inertia of the drivetrain

    Yup, and I read that higher gear accelerate has been enhanced the most. So overall this would translate to that the rate of putting-power-to-the- ground is increased ? There is a slight increase of area under the curve according to dyno graphs posted on iwsti.com.

    I was being curious and was looking forward to get a ride from someone who has the driveshaft because $1200 is no chump change.
