What rated springs do folk run on single way Nitron Adjustables? 
450f/550r on mine Simon.
Obviously somewhat softer than the boyz who only use their cars on track, but I find the above āacceptableā for road use, & great on track with the dampers stiffened up a couple of clicks.
I run 550/700 Randy spec - itās a heavily track bias setup.
Same here on the 46mm"sā¦ but still lovely and compliant on the road 
Same here Simon, lol does a lightweight S2 count 
Cheers chaps - Iām after a new set as one spring appears rather beggered and I canāt for the life of me find out what springs they came with 
Just for nothing more than trivial value the new V6 nitrons are running 550f /1000r
Battleship specā¦matches the paint job
Oops I have Ohlin 46ās!
Mine are not āthatā bad on the roadā¦theyāve been on there quite a while now so Iām used to them. Iād like to try some 46mm or Ohlins one day if I have the Ā£Ā£Ā£.
Im running randy spec 450/650 but I find them a bit harsh on the road, which makes me think the dampers are turned up a bit high as it was only a pure track car before I bought it and it will be 100kg lighter when Ive finished with it so maybe i wont need to run such hard rates
How old are the dampers? What car are they on S1 S2 ETC Do you know if they are fast road or track
I can give you a good idea of what they would be fitted with today. Or if you look at the end cap (near adjuster ) there is a 4 or 5 dogit build code, get me that and i can find what springs where originally supplied.
My s2 is on 3 way 2013 spec Nitrons with 550/700 springs and on track I was really surprised how compliant it wasā¦I have no idea about road use, not driven it on the road yet, honest
my S2 is running 550\750 1 way nitrons and it is great on the road as well as track, I just dial back the dampers 6 clicks for the road and more and it gets too bouncy!
