How much torque can the stock clutch handle? Has anyone had it slip with aggressive driving or racing? Who makes aftermarket clutches for the f30? I didn't find a lot of HD clutch options for even the e9x 335i. Sachs makes an organic full faced disc (probably not a lot different than stock) that handles 540 NM and also a solid 4 puck clutch for the e90, but nothing in between. I have a kevlar full face / puck hybrid (with sprung hub) on my other car and it is very streetable but with a lot of bite too. Will a clutch from an e9x fit the f30?

And no I'm not planning on blowing the clutch in my brand new $60k car, just wondering how well the stock clutch can take the abuse that I will inflict on my $60k car.
