Here are some more pictures and my input for anyone considering this. I hope they can help someone in the future.
2007 E90 335
The 1-2 shift feels so much better! Great improvement over stock. Other upshifts feel good but the difference isnt as dramatic. I wouldnt suggest this to anyone who doesnt drive their car hard. Often.

The only thing holding it in place are these two tabs. Pictured here 90% removed.

All done. Like I was never there.
