Returned from my 3 day event at WGI with the BMW club, Genesee Valley Chapter.  i now function as the intermediate & advanced group lead instructor, title bigger than the actual job.   
  
New BFG tires are no sticker than the old Yoko's but retain the same predictability-which I tested a few times.  A couple of the other instructors commented to me over the weekend how they enjoyed seeing the old Z "sliding around" the track and how nicely it rotates.  Funny, I thought that was normal... 
  
Brakes are fantastic -  Raybestos ST43's.  A bit noisy on the steet, which is great as I pull to a stop light.  They require zero warm-up, right now grip all the time, easy to modulate and I wasn't able to explore all they have [chickened out of going too deep just yet] but will experiment more at the next event. 
  
Turned 24,000 miles on the swap on my way to the track and so glad I did the LSx swap and grateful for all the help I've received from the collective Z brain trust here!
