New Clutch Recommendations
Hello, I recently installed a JB4 on my 2011 335 xDrive with full bolt-ons and after some pulls the clutch started to slip in the power band (5500-7000rpm)!
Any recommendations for a nice strong clutch that doesn't involve any other modifications? My apologies if this has been discussed before |

+1 on this, very reasonably priced for OEM BMW fitment and warranty. Holds power like crazy while keeping the feel and weight relatively the same. My clutch pedal only got a hair heavier, but the engagement point feels worlds better too.

OP, unless you have loftier power goals such as a bigger turbo and maybe PI stick with a dual mass flywheel. Only go single mass if you intend on going further. Should you want to do so you would then want a Spec 2 +, not the BMW clutch.
DMFW and 335Is clutch < 500 whp SMFW and Spec 2+ > 500 whp |

That being said. I do prefer to recommend the Spec Stage 2+ because we see many folks with 335is clutches coming back after a short while needing to upgrade again. The 335is/550i clutch is rated just shy of 400WTQ where as a Spec Stage 2+ is rated for 545 TQ (approx 470WTQ) and it's considered conservatively rated. The 2+ also drives much like stock and can handle a lot more abuse. |

i went with the 335is clutch on my n54 with full bolt ons. my car had 120k miles on it and the flywheel looked good so i left it. worked great for me and had zero issue. ECS Tuning has the kit on there website for a very reasonable price, the only other thing you need is a clutch allignment tool thats around 30 bucks (atleast i needed it for my 07')

I think my clutch is starting or is slipping. I started doing research on what to buy and I am reading that I also have to buy a new DMFW too?
From what I am seeing the DMFW is more expensive than the SMFW. Why is not recommended to use a SMFW if you plan on staying under 500whp? |

If you don't mind the noise, there's no reason you can't go with a smfw and stay under 500hp. It's just that if you want more than 500, the dmfw starts to cause issues apparently and then you have to go smfw.

You can get rid of most of the rattle noise by raising your idle with tunes that are capable, like MHD. If you want to avoid the noise and don't plan on going over 500WHP (or MHD) consider the DMFW. Over 500WHP, the DMFW becomes imbalanced, causing chronic misfires. |

So regardless of my power goals, when I do change my clutch I also have to buy a new flywheel right? I am currently working on a 450-480whp street car. I think that's plenty of power to have fun with on the streets and still be a "good" daily. So high durability from the clutch though not a must will be highly welcome. Any in particular you can recommend? |

We always recommend changing the flywheel, especially if you want to stay with the DMFW. The stock one as it ages becomes worn and imbalanced so although the surface may be fine, the internals will be out of wack eventually. |

The Spec clutch has more holding capacity (higher torque rating) then the 335is/550i clutch kit. |

Is it from the gear lash in the transmission? As cars have had SMFWs forever and never had any noise. So what changed here; So odd to me.
