Just found a leaking front strut so I guess it's my turn to swap in some Bilsteins. My main criteria is ride quality. I feel the stock shocks are unnecessarily harsh. I had Bilstein B6 on a lowered BMW and they were nice on the track but somewhat harsh on the streets.
On the forum, there's a few who have mentioned their Bilstein B4s were firmer than stock, and they definitely wouldn't want firmer. Those with B6s say they're firmer than stock but ride quality on the highway is better than stock, I'm guessing in terms of sway control? It's definitely possible the monotube B6 has better initial give for less harshness than the twintube B4, but the BMW sure didn't feel that way.
Anyway, an extensive search for forum mentions of Bilsteins showed only @Tyler-98-W68 having used both B4 and B6, and he seems to be banned for some reason. So I'm just curious if anyone else has tried both and has an opinion on the relative harshness of the B4 vs B6 vs stock on an average shitty street filled with expansion joints, manhole covers and potholes, and highway speed expansion joints.
The stock shocks feel harsh on low-speed streets, but I don't notice expansion joints on the highways around here like I do with the RV so for me the stock setup is more of a lower-speed harshness problem. It may also be more related to the relatively stiff swaybars than the shocks, which may make all the shocks feel about the same at lower speeds, I.e. potholes at 30 mph.
