Well the bilsteins went in on Saturday, with nice big yellow bump stops and 450lb springs.
Instantly they felt much more controlled than the Konis that were in it, in fact I had to up the damping on the rear Konis to match the front bilsteins. Very happy with them so far - comfortable at low speeds, and the variable damping seems better at coping with big hits too.
The spring rates are much better than before (F 650, R 450) now F 450, R350. The rears still are too hard, and 'skip' a little struggling to keep the back end tidy. Will change over to some 275lbs or 250lbs and see how I go soon. Just can't be bothered pulling the rears out at the moment!
