10kg for the wheel! Was that the front or rear? Either way, that's incredibly light. BMW state 12kg for the Performance 225 rear wheel in 19" and 25kg including RFT. 10kg for a 19" is getting near forged rim territory.
What rear camber settings are you running now, closer to M3 per chance?
Did you get each corner weighted too?
One question I've been wanting to ask you is about the auto gearbox. Given you're a real driving and car enthusiast. How do you get on with the auto and how well does it work in manual / paddle mode around a track and spirited road driving?
