We have fixed Bilstein issue with raised ride height on both E9X from the get go and on the F8X Platform with the latest batch of dampers.
Part of the reason why the E9X Dampers took so long to come to the market was that we changed so much from Bilsteins own design they had to run them through internal compliance testing before they would produce them for us.
Please read the reviews on the F8X forum yourself. The reviews are mostly positive. Of course you can't please everyone!
