That being said, anything that uses a long bump stop in the rear will have some level of progressive spring, especially stock. Bilstein has you re-use stock bump stop so in addition to the coil spring progression you have the bump stop progression as well. If you look at the RCE T2's they have a very small bump stop that exists (mostly I believe) as a safety measure to prevent harmful bottoming. If you look at KW V3 kits they spec a softer spring and more bumpstop, even though the spring is linear their bump stop introduces progressive behavior not so different from the B14/B16. The stock setup is pretty progressive due to some long bumpstops, if you don't hate the stock progressive spring odds are the Bilsteins or KW's wouldn't bother you. Tuned well everything works in harmony, as an average amateur odds are if you're slow on course a linear rate spring isn't going to magically make you faster, however with experience you can pinpoint areas where the suspension may not act as desired and tweaking spring rates and damping profiles can yield benefits to you as a driver. I am interested in giving my B14's another shot, I wonder if I can get them converted to the B16 adjuster without breaking the bank... |

Edit: and their double adjustable is legit, there was a conversion using their shafts a few years back here. https://www.ft86club.com/forums/showthread.php?t=100216 |

https://www.google.com/url?sa=t&sour...1vRsIo4q9fw3U9 When I talked to fcm about 5 years ago he didn't have any experience with the pss10 preferring to stick with revalving the non-adjustables. Dynos are certainly scarce, here's one; https://forums.m3cutters.co.uk/threa...r-sale.197264/ The criticism I've heard second hand about the current Bilstein single adjust is that it doesn't offer a wide range of adjustment and is more a fine tuning advice, at the amateur level us hack jobs sometimes need a bigger change in feel to assuage our egos that we've done something different. |

I read it years ago while researching my purchase decision. You're probably just as capable of doing a search as I am. Sorry I couldn't be of more help.

Cheers to that, last we talked I don't think you had spent time playing with them yet, glad to hear you like them!

@solidONE
https://f87.bimmerpost.com/forums/sh...51&postcount=3 Found another forum post with PSS10 dynos, BMW chassis, whole thread is neat with a couple different dampers dynoed so you see some different philosophies and capabilities. Anyway, I stumbled across some S2ki posts bashing the Bilstein for an 'inconsistent adjuster' which their criticism was one click out of 10 doesn't necessarily create a 10% change in damper stiffness across the range, you get some big changes going between clicks 9 and 10 and it looks like going from say 2-3 isn't going to feel like a change at all. As long as it's repeatable and predictable that's a decent adjuster imho, it's a damper on a budget for certain and there are sacrifices made but it's a contender. |
