I've had my G87 for three weeks now, I set the M1 button a few days after collecting the car, made sure it was a step up from the "Efficient" but not too much of a carefree/bonkers setting as this is my first ///M car. The settings I've added to the M1 button seem to be about right for the roads and journeys that I do here.

The M2 button will be set in the spring for when the weather dries up/warms up.

My M1 and M2 buttons defaulted to factory settings after the update, which deactivated the auto-rev match.

So I am out driving and the first time I go to downshift, not knowing the car isn't going to blip the throttle, I immediately let the clutch out and the car locks the rears and the rear end started to step out. It sorted itself out quickly but I was not prepared for that behavior.

Lesson learned, be careful about iDrive updates changing your M1 and M2 settings.

Were you going around a turn or going fast?

Probably about 45 coming up to a curve that I was slowing down for. It was exciting for sure.

M1 is everything in sport except dampers in comfort and the gearbox which is in manual middle mode.

M2 is everything max sport and traction control fully off, manual 3rd gearbox setting

Yeah I was curious. I had a "high powered" BRZ. It had rev matching in the tune so I'm trying to see if I remember having any issues like that. But good to know for the future.


When the M buttons aren't set what's the default? Is it blank?

M2 is kill/fun mode. Engine Sport +, traction control to 3, trans in D3, sport suspension. To be fair I'm here most time after warm up.

M1 is just engine in sport, rest comfort. Gets a little volume and fun cruising or warming up.

The default M settings aren’t blank, I’m not at my car but they are populated. It’s easy to reset to the default too, if need be.
