I know some AWD DSM owners didn't like the launching results they got with aluminum lightened flywheels, but we don't have all that drivetrain to accelerate and we don't get insta-traction, so it technically "shouldn't" be as much of an issue for us, but I naturally can't be sure...

that is unless I get a lightened flywheel in the near future, which is not out of the realm of possibility :)
