LOL, nice choice of words. Blah blah blah, right? The forum's full of idiots, none of us have ever ghetto modded our own suspensions in the past and learned from our mistakes and tried to tell others? Bah, it must be OK if you think so.

Negative. The majority of cars on the road have linear springs, it's the bump stops that are progressive, and the bump stops are so tall that you hit them often. They're more than just crash stops they are integral suspension parts now. I don't know about all 135i springs specifically as I haven't had this car apart yet, but even for us the 2011's are supposed to have gone to a linear spring and if you look that's exactly what the poster has.

The short version is - aftermarket springs, given that they likely have different rates, need some thought put into how well the stock dampers can control them. Assuming you can throw anything on and it'll be fine is naive.
