No problem at all. The Wilbers fork springs are a nice match the Wilbers rear. Wilbers recommend using 15wt fork oil with their springs, however I chose to use either 10wt or 12.5 wt instead (I can't remember). The roads up here in New England are not the smoothest, which was why I decided against the heavy oil. The only other thing I can think of adding in the future are the Race Tech fork emulators.
Geoff, who did you buy the fork springs from? Apparently it was not Affordable Beemer Services.
