I have a 20 M3P and agree, comfortable but they suck in cornering - not near enough support! I use my left knee to brace against the door, but doesnt help on right turns + passengers dont have an oh **** handle available - love the car. but these two small issues would make it that much better and I would have gladly paid a few extra $'s for such. I looked to see if Recaro had a drop in drivers seat - no such luck. and haven't been able to find anything so patiently waiting for options
