Chris, as I said, i have no personal experience from the Konis, so i cant say which is better. Perhaps we should meet and compare one day.
Besides my opinion is based on a few days of testing while yours is for 15000kms so its much more reliable.
I was about to go for the Konis too, but most professionals and non-professionals sugested the B8 while they kept
warning me about the Koni's hardness. Not just on Alfas but on every other car. Perhaps most of them dont know how to adjust them properly
(you cant trust anyone but yourself nowdayz
). The only good opinions i v heard about konis where here and on the greek alfa romeo forum but
then again "good" or "bad" is a very subjective matter, what i may find good, you may find it awful and vise versa, so we all should be kind of cautious before making decisions that cost a lot of money. Basicly the fact that i had pesonal experience from the B8s while not from the Konis, made me choose the Bilsteins.
I also am a bit upset, since i might encouraged someone to buy the B4s when posting my first positive impressions after fitting them, while they proved quite insufficient for the circumstances after some months.
So I d like to make this clear, DON'T just rely on my opinion on the B8s, its just one owners opinion (while the konis are appreciated by many alfa owners) and I only have them for a few days.
