I have it in my notes from last winter when I replaced/serviced I think, I'll check when I get home this evening. (if I remember)

Of course I did. Thanks for the reminder.
So--
Sonic 1.2kg's are 315mm in length.
I cut my spacers 134 mm long which gave me 18 mm of preload
Oil level is 128 mm down, about 550 cc
Front end feels just right to me, and we have really beat up pavement here in NH.
Sorry for the delay.

:capwin:

I will add that all of Sonics springs of that diameter are the same length regardless of compression rate.

Thank you very much for the information.
I ended up with 131mm spacer and a 2mm washer for 133mm and got the same 18mm preload.
