Ive got use to it to be fair, but then I go drive a few other 1 and 3s, and the difference is night and day. They should have come from the factory with the B1 dampener/spring rates.
Its totally worth it, quaife changes the car. With the DSC enabled, pushing the limits with a stock 130 results in the dash flashing lights and sadness, whereas with the quaife its something more akin to a "track mode", all the nannies are still on but because the wheel speed doesnt differ like an open diff ,the point where nanny steps in is much higher as shes oblivious to the fun being had. DTC just pushes the limits out further, and off is full fun mode Its way more tractable off the line (Can get .5s faster than BMWs 0-60 numbers, on a car with 260,000km on clock and no "performance" mods), way more predictable at the limits, and doesnt skip and crash around the place on NZ's shitty B roads.
Got a VTNZ wof on it the other day, tech thought the odo was wrong or dash had been changed out.
