No problem I am debating whether to fit one in the near future with a stock clutch. I have just fit a SMF with Stage 3+ clutch to my N54 135i and there is more chatter and noise at lower revs. My 130i is highly modified but still used as more of a daily as it is so practical. I wonder if the additional chatter would get on my nerves (I do have a 3.91 diff, Race poly bushes, GruppeM intake etc so it is definitely louder than OEM already!!). Do you notice much additional power at the wheels and quicker engine response with the SMF on the 130i?
