More things I've learned...
 

While I was installing the springs and shocks, I was going to install adjustable rear endlinks. Guess what? The set I bought from Way Motor Works doesn't fit.

It seems that 2010 Minis have different end links. The lower stud is now longer at 37mm vs the older link of 23 mm. The upper stud is the same. So the new lower link doesn't fit through the control arm enough to get any thread engagment of the nut.

Way is looking into it...
