Spax are probably 5 times cheaper than Ohlins and can be bought from Morgan :-)
Getting the bottom bolt out of the rear shock is a labor of love, so I would rather do it once and get adjustable shocks?
So you did put Spax Adjustables all the way around? Did you raise or lower yours , assuming you purchased a set?
The only benefit I can buying them from MMC is they will fit without hassle.
