love your setup, would love to get an alcantara steering wheel....
Few months ago, i spoke will ronald from autosolution, since his short shifter are know as the best available for the e46 m3, i contacted him about a f80 short shifter and he's making an ultra shifter for the f80. so i'll order one from him this week, this give another options to us for ssk.
he told me that the conception design is the same as the e92 m3 model and the e92 m3 ssk look like this, very high quality, low tolerence hand made/assembled short shifter, 20% reduction from what he told me
