1 mm raises the rear about 3mm IIRC

Did  you MEASURE the actual axle to triple length fully extended fork? 
That is what counts. What sticks above the top triple is not important. 
Or axle to steering head. PS: I learned that from Zoran.

I just posted before him so I can get back to first on the list.
