My vote is for 75 mm. I've got the Eibach lift now that has a 2.5" (63.5 mm) front lift and TJ springs in the back. I'm wanting a little more lift and will probably put in a spacer if getting these new coilovers is not an option.

If the outter body is threaded you can always dial in more or less lift but you will change down travel either way.

Having it set for 75 mm you could put it all the way to the top to reduce the amount of lift to less than 2" or push it to the bottom to get more than 4". The flexability would be awesome.
