And FYI you can fit four unmounted 275 RS3s in the backseat of an e92. Not sure if you have tried yet (I have done four in the back seat and then tools/etc in the trunk). It's a tight fit but doable.
This is my first set of RS3's and my lap times are still improving, so not sure if grip is down and driving is getting better, or vise versa. I usually drive (1hr, 15 mins) to track on my streets and change to RS3's (in back seat) at track. So no more room for new tires. I guess I could also drive up on RS3's and take new set as you mentioned.
