I kinda want to go single mass. My buddy has one on his vag and the chatter isn't so bad.
Is there a good single mass that would work with the 550 setup? I'm sure that's the right clutch when mine goes just not sure about the heavy dmf. A light flywheel is like my favorite mod. I'm at 36k and things are just starting to feel different .. not new. It may make it to 60k, I'm not sure I've always sold or blew up a car before having the clutch go. The parts aren't very expensive if I had a lift I'd already have a light flywheel in. |

I'm more worried about the flywheel than the clutch. Also, I like to leave some headroom. If Stage 2 E30 is basically the limit, then I'd want something that can handle a bit more.

I like it in my GLI but idk if I'd enjoy it in my 440i. It's fun and peppy but when you just want to cruise and relax, it can be annoying. especially with the A/C on. Quote:
I'm not sure about headroom. I'll need to do more research to see if anyone is slipping the 335is clutch. But a tuned 550i makes similar torque to us, so probably 500wtq or so might be close to the limit? We'll see. |

You shift just before 7k and revs either hang there or actually go up while you are shifting. |

Clutch Upgrade 370mm Brake upgrade CDV delete I want to pair the CDV delete with at least one of the others, but it's the only one that's free i may just bite the bullet and do it on a slow weekend this winter. |

Will this fit a 340i? It's not listed under the section listing what cars it fits

it will fit, it is just not the OEM clutch. Our OEM clutch is the same as the e8x and e9x models that they have listed.

Awesome, thanks. Been trying to find a stronger clutch to handle extra power while still keeping daily drive-ability. I'm only going stage 2 with downpipe route, so this should be perfect based on everything I'm reading

Yep, you're in the same boat as me. It should be an oem feel, just with slightly stiffer clutch pedal due to more clamping force. I almost feel like we could just swap pressure plates but not sure they're sold separately. And it would be so cheap relatively that it's probably not worth it, when you can put a fresh disc in at the same time.

I've skimmed through this thread and let me help convince you to delete the CDV. My clutch was slipping FBO running the MHD Stage 2+ 95 octane map. It slipped much less running 93 and not at all on MHD stage 1 & 2 tunes. With that said, I was about to spend $1500 on a 335is/550i clutch with installation until a friend and fellow enthusiast convinced me to try the CDV delete first. The CDV has been out for about a month now, along with me running MHD Stage 2+ 95 octane and I've had absolutely zero slippage. Not to mention the clutch feels loads better than it did before IMO. Hope this helps.

my clutch needs replacement, 22,500 miles on the car. Just went stage 2 last week and almost immediately started getting slipping when pushing the car hard in any gear. drive train malfunction light came on and both the codes were for clutch issues. Going to upgrade to 550i/335is clutch in hopes of solving this issue

Looks like I'm definitely upgrading my clutch before going stage 2 or E85.

Anyone have any idea if a short daily commute would be bad for the clutch?
Back story, I've owned several manual BMW's, including an F80 and a stage 2 (JB4 + downpipe) 340i. Never once had any clutch issues. I recently bought a pre owned 2016 340i xDrive 6 speed in June. Had just over 19,000 miles when I bought it. Was told it was owned prior by an attorney who worked from home I have an extremely short commute to work every day, .8 miles one way. So when I get to work in the morning and turn the car off, it's still cold. Same when I leave work to go home at night. Monday to Friday. Car now has 22,500 miles Recently tuned the car to stage 2 with BM3 and downpipe. Almost immediately started having clutch slippage. Drivetrain malfunction came on and when I pulled the codes it confirmed the clutch was having issues. Considering I never had clutch issues after 20K + plus miles on my last 340, I'm curious as to why I have issues now. I'm figuring either the previous owner was very rough on the car, OR the short commute I have is killing the clutch. Any other thoughts or ideas? I just ordered the 550i/335is clutch for replacement but if it's the commute killing the clutch I'm gunna have to buy a $1000 beater to drive back and forth to work (seems silly I know) Or if it's just a fluke or a result of the previous owners driving style, I'll replace the clutch and move on with life

Short commutes are bad because they don't let the engine and car fully warm up. You should take it for a nice highway drive on the weekends or maybe out to dinner once or twice a week. Clutch wear comes from transferring torque from the powertrain to the drivetrain. This can be exacerbated by adding more power to the car, launching, or slipping the clutch, or a combination of the three. |

Agree with G.Newt. It's bad for the engine, particularly the fluids. You want your oil to get up to temp, otherwise you are wearing our your engine components faster. It also can prevent condensation from burning off, which makes your oil more effective. It sounds like you're driving enough, though, if you put on 3k miles in 5 months. The clutch, on the other hand, shouldn't have an issue. It's just OEM organic material made to work through a wide temp range. It's kind of like stock brake pads. If anything, too much heat is what would kill it. (i.e. slipping/burning up the material) BUT, if it's anything like the clutch replacement my friend did, the clutch very well may be fine. The pressure plate just can't hold the torque. I'd argue that BM3 has more torque and potentially higher peak boost at lower RPM than JB4. It's also a different car, so the clutch could just be a bit weaker than your previous F30. For sure weaker than the F80 twin disk clutch. Unfortunately, you'll need to pull it to do a diagnosis of why it's slipping. I don't think we have any inspection holes on our trans or any way to see the clutch disk. |

Thanks guys, I appreciate the knowledge. I'm glad short drives don't affect the clutch, now I won't have to get a beater lol. I drive the car for long periods of time on the weekends, and usually at least once or twice during the week I take a long drive. I ordered the clutch kit from FCP Euro so when I have the new clutch installed, I'll have the shop take pictures of the old clutch and post them here for reference. Looking forward to actually being able to use all this power now
