Koni FSD's absolutely worth it!!!!
Avalys couldn't have been more accurate on his assessment. I live in Toronto and have some horrible roads here as well. I just changed out my stock shocks to Koni FSD's and they are amazing. I was driving on roads that I thought had been repaired because I couldn't feel the same horrible pot holes. Also, my handling has improved drastically. The only thing I might have done had I been living in a warmer climate with no snow is dropped the vehicle an 1"-1 1/4" for a lower center of gravity. Anyways, I'm so happy that I can't even explain how it feels to drive in my 328i now.
I owe it to this thread otherwise I was gonna end up getting stock shocks again. Even my mechanic said that my car rode better than some of the newer cars he's driven. Worth every penny!
Mod Bargains also has the best prices (Trust me I don't work for them, I live in Toronto so I can't even if I wanted to lol).
