Ah I put too much in mine then. So 4mm is what it should be not 5mm. That explains a lot thanks.
Do you know what length the shock shaft is after you add those shims ? As the rod end can be screwed in more or less which will give a different droop setting also ? I have mine set at 19mm with the 5 limiters inside the shock but I could make it a lot less if I screw the rod end all the way in. I think 20mm is kit length.
