SHipping BTW was $98 from VAC (UPS) and $68 (FedEx) to ship the core back.

Here's my seat of the pants take on how the Quaife improves the driving experience.

On dry pavement with DSC fully on, ANY wheelspin led to an abrupt cut of engine power. I believe this is because in DSC the brakes aren't used to create a pseudo LSD. I can't prove this and can't find it in the literature. With the quaife it is harder to spin a wheel, so DSC throttle intervention is raised. It will still happen if you light the tires up. DSC allows some wheelspin as long as both rear tires are spinning at the same speed and aren't spinning much faster than the fronts. THis is why I believe the LSD function of DTC is off in DSC.

I still haven't driven the car in DTC mode, primarily because there isn't a need to. Before the quaife, if I was going to accelerate hard, I enabled DTC to avoid DSC throttle intervention.
