Downshift to 2nd gear rejection - Solution

I know we've discussed this elsewhere, but I thought it deserved a separate thread for someone searching later.

To recap;
Under certain loading conditions it can be very difficult to downshift into 2nd gear.
For me I experienced this issue consistently at one track that we run.

Update:
After installing UUC tranny mounts, we ran that same track today.
In a nutshell no more problem.
I was able to run all day with absolutely no issue downshifting to 2nd.

The entire day I missed one shift, which was without a doubt, driver error.

Problem 100% resolved in my case.

edit:
My results were duplicated by another member on RE mounts.

Sorry to go off topic. What track do you go to? Never seen another M Coupe at the track!

We were at Shannonville yesterday.

Nice! Which group do you go with? I usually go with Touge or Kplayground. Neither are really BMW groups, Touge is random, Kplay is obviously Hondas, lol.
