I've noticed your tyres are 18" non run flats and larger profiles - Is this because you may consider track days ? Does the run flat indicator constantly light up ?
I'm sorry, I just saw your post. My tires are the factory profile. F31 comes with 255/40/18 rear tires. I simply went to 255/40/18 on all 4 corners. Run flats have very stiff sidewalls and don't offer as good of ride quality and performance as non-run flat tires. My car came with the track handling package - which deletes the run flat tires. I don't plan to track the car.

Are you confusing the low pressure indicator with a "run flat"? Low pressure occurs if your tire has a puncture and loses pressure. Run flats allow you to continue to drive without air pressure. Otherwise a run flat versus non-run flat tire is normally operating at the same pressure. There is no such thing as a "run flat indicator". There is a low pressure indicator but, again, that will only illuminate if the sensor detect low pressure. it doesn't care whether you have run flats or not.

Hey, sorry for bringing back this old post but on the off chance you still see this, curious if you were using stock shocks/struts or ones meant for lowering springs?

I didn't install dinan bump stops on my e90 xi when I did my dinan springs and bilsteins - wonder if this is why it feels pretty bouncy ?
