Not to make a new thread so question for those that have these or Ken.
1. What is the free length measurement for the original black springs front front/rear?
2. When the front/rear pre-load is adjusted correctly at -5mm(from free length), what is the measurement of threads available from the bottom of the spring perch to the end of the threaded part on gold housing for front/rear?
ie. as someone has measured in this picture showing 4.5"

do the F&F type 1's come with an instruction manual?
Do you know if F&F has Type 2.5 coils for 1996-1999 BMW M3? If they do, what's the pricing?
I tried searching on google and couldn't find anything. Only TCK, Megan, Variant, and some others.
