Hi buddy, i also have BC installed on my 335i few months back. Here is My setting for your reference are: {Front} 9 clicks Start from the SOFT and {REAR} 12 clicks also from the SOFT setting!
To me they are stiff enough now and that change the car character alot, which make a hugh difference specially when doing corners actually!
To adjust the rear suspension they should come with a pair of cables which you can bolt them on top of the rear shock for easy adjustment (but you'll need to drill a hole in the boot to fit them) OR you can take all the rear compartments off to get access to the rear shocks for adjustment everytime when you fancy to reset them again, hope that helps you!
Am using non RFT now after installed the BC and it feels soooo good since
