I have an E92 DCT......if you plan on doing quite a bit of track work, get the 6MT.... bottom line is when pushed hard the DCT does some funny stuff....hopefully the software update will fix it, but we'll see....
With that said I do not regret getting the DCT...because the other 97.68% (4300 miles total, 100 on track) of the time I am not on the track the DCT is better......
