Does any of you guys tried M# rear sway bar on 335XI? I have a question about bushings, OEM 335XI bushings will not fit M3 sway bar since it is bigger, will OEM M3 bushings bolt on to 335XI? I'm having a dilemma, and talking with my mechanic, and he is saying that M3 bushings wont bolt on on 335... Anybody had this issue? Or maybe have part numbers for bushings?

Updated. Happy xi modding!

Sorry for the newbie question but I can't find the eibach springs for a e90 335xi, the only ones are for the 335i. Will these (2092.140) work on the xDrive http://www.**********s.com/Eibach-Pr...90-E92-E93.htm

I don't really care much about ride height. Looking for improved ride and handling. After hitting some bumps on the interstate and taking some turns it feels mainly under sprung to me. Between the shocks and rft, shocks seem stiff enough.

Any thought?

Here's a thought: xi with Bilstein HD and stock springs review

I appreciate the suggestion, but it isn't going to do much for mid corner lean or highway float.

Really? Fixed those problems for me, even my track instructor was impressed. Have you driven another car with them installed and found them not to be what you wanted?

So KONI FSDs aren't on the list, but a number of sites online are offering an FSD kit that is advertised to be for the xi: part number 21004123

For example: http://www.ecstuning.com/BMW-E90-330...123/ES2626473/

I ordered a set, and they should be waiting for me when I get home. I plan to install them this weekend (presuming they do fit).

One thing I wanted to mention was that the m3 front swaybar has been known not to fit xi but brentuning was able to put it on his 335xi. I don't know what he has done to make this possible. I have called and emailed him multiple times about it but received no response. Does anyone know how it maybe possible to fit the m3 front on our xi cars ?

FYI, the KONI FSD part number 21004123 fit perfectly on my '06 330xi. Took it on a long drive yesterday and I'm very pleased with the improved ride.

Was your car lowered? What type of springs? I'm looking at the same shocks for my lowered car.

[e4tmonkieshyt]

are there any companies that make longer endlinks for lowered xi cars?

[koches]

Anyone have a list for a perfect street setup for DD and spirited driving on the back roads?

No, not lowered. Stock springs.

is that stock sport pack setup or just normal? ride height is different is why i ask. i see you are in pothole/crater county like me (the northeast), my sport pack suspension in the front was incredibly hard over even the slightest of uneven roads since day one. the fronts felt like they had almost no travel and i would be slamming into the bump stops all the time. Jan-May were horrible road conditions and the cause of many wheel/tire issues here. That and pretty much 24/7 war zone roads going thru the city/staten island/NJ/etc...

did it help smooth out any of those issues??? i'm wondering if i can go to a non sport suspension just to get more travel and/or if they have an aftermarket solution which can give me more travel? i don't care about wheel gap.

i need to change out my shocks since i'm over 100k miles and one shock blew out in staten island (nice present of a huge leak in my driveway). i was thinking of b16 coilovers or kw v3's but someone told me that both of those would not do anything for what i am looking for.

Getting rid of the run flats plus going with the bilsteins def help smooth out the ride a lot. The xi doesn't come with sport suspension.

I have a question about the front end link bushings. I thought I read on the suspension forum that we can install M3 sway bar end links (and/or bushings) in the front. Is that true for a 335xi? Or is it just for the "i" cars?

Thanks,
Harry

I think it's only for the i

[dbkaplun]

Here are some more I found that definitely fit the xi/xDrives:

• JRZ RS1 (special order)
• TCKR Single Adjustable Coilover Kit (Koni shocks, TC Kline springs)
• Intrax 1K2 (Intrax shocks+springs)
• H&R/Bilstein Sport Suspension Package (Bilstein shocks, H&R springs)
• Nitron - NTR R1 Coilover Systems (Nitron shocks+springs, *possible* fitment)

I'm surprised nobody's mentioned these yet!
