I have M Sport Springs off my 128i that have 18k miles on them. I don't know if they are any different than the 135i M Sport, but I can sell them to you cheap

What Im trying to say is that I have the M sport springs on my 2011 135i, and BMW changed from progressive springs to linear springs in the 2011 MY. They ride pretty firm already (cant recall their spring rate). I may skip the sway bar, and get a a Koni sport/ Swift Spring combo that Harold is selling on special HPASHOP (on sale for $926USD)
I will touch base with him on best options to match shock and springs, as I know the Swift Springs will drop the ride height some, but I prefer stock height ...
