My understanding is the E92 has very little travel to begin with. BMW uses relatively soft springrates to create the compliant ride but when driven hard you are on the bumpstops most the time thus effectively raising your springrate.

My question is then this; is this a progressive or linear setup from the factory? They are linear springs with progressive bump stops. So in the case of lowering the car with say Swift springs for example would you rely on the higher than factory springrates with short bumpstops or keep the OEM E92 ones to create an effectively even higher springrate. I would think the E36 bumpstop would be better.

I recall a thread by Malek using E36 bumpstops and trimming strut guides to regain travel and have a controlled suspension while lowering. I would trust his judgement being one of the most accredited suspensions Guru on here.
