I was thinking the M Sport sway only because there are no other choices. But you sure Kartboy endlink will works with E90's sway on X1 with no side effects?

Para can chime in, but stock 335 end links may work too?

I also found a parameter called E84_AX_REF_DIFF_LOCK. Any idea what this is? Check this out: Quote:

Never tried stock end links from a 335i but they might work. We just used the subaru ones because we had them unused right there and they fit absolutely perfectly.

http://www.bmwclub.ru/vb/showthread.php?p=21281896 But anyway, if I'm you, I'm deactivating that and giving it a try on your next lapping session. If that's not doing it, then try setting Diff_Lock (if it's in the xdsc) to 0. BMW describes their e diff as an electronic locking diff...so it's certainly related to the locking aspect of the rear end. Can't hurt anything by trying.

I'll take a peek at my 135's rear endlinks and compare them to a set of WRX/STI endlinks I have lying around to be sure.

I will report back, but if we could figure this out there are a lot of people who would benefit from it. I just spent the last hour googling it again and there are 20+ threads I found asking how to disable it with no definitive answers, and two or three people claiming they had but not posting how. |

I guess the question is, is the Performance Control instead of BMW ADB-X (like a higher level of it) or once I code out performance control, will ADB-x still remain?
It would be really interesting if in my car Diff_lock is set to off and performance control is set to on. I will check. |

Thank you Para and Premature! Kartboy seem much better (stronger) than OEM M3 so I should go for that. I looked up your post about putting in M3 sway and you said it is a pain; what is the reason? |

It is a pain because you have to drop the subframe in the rear. Labor will be $$$ if you are not doing it yourself. You might as well do the rear subframe bushings and any other rear suspension work you plan on while you are back there as it will save you lots of time and effort down the road.

That's why it makes sense to do the rear subframe bushings while you're back there. Whitelines are the cheapest and easiest to install (2 piece poly vs. something you have to press in). Use the jack/torch method DIY to get the old ones out without any special tools. http://www.topgearsolutions.com/whit...g-bmw-e90.html

Did ANY E90 come with an optional LSD anywhere in the world (maybe a 335is somewhere)? If so, we need to get their DSC dump and we'd 100% be able to shut it off. I believe people have done it without changing the VO.

Not mechanical lsd I think, however 2007 335i had a strict open diff, not the e-diff programming. Could compare the parameters and see what is different to cause the locking behavior. For the 2007 cars when DSC is off, everything is off from what I have researched.

^^^Yeah, it's safe to say with diff and lock in it, it's related to the e-diff which you're certainly running.
If I had an ice-skating rink handy, I'd run out, shut it off and test it right now. But I have been drinking...

Couple quick questions guys:
Para - Where did you see the KW V1 for just over a grand? I can't seem to find them for less than 1600 or so. Regarding the Whitelines, are they lubricated (graphite impregnated?) or are they squeeky? I am looking at the AC Schnitzer springs but wasn't planning on doing the struts. Now I am thinking of just going with the KW V1 if they can be found for around a grand. The M3 rear bar has been on my list, so might as well do the bushings. Also, Para and Apex, your both pretty you know... |

Non-update, update. Rear Bilsteins will be in on Tues. Should be about an 30 minutes to toss them in and I'll post the results. I'll try them with stock length bumpstops first, then trim if still needed.
Looking forward to results. After this, it's convincing wifey she wants a meth kit. I gave her some E85 the other day, and I think she's addicted...so perhaps it's an option.
