Thanks.
Two monroe kits. There's not much rebound in the foam shock mounts. The new shocks will take care of the bounce. Anyway, not a big deal, just commenting that leaving the foam mounts vs. the rubber is a small way to take the edge of the shocks, as you expressed concern over ride firmness.

Go for it.

Need advise on what to get for my e92 335i.

Nearly FBO
Sees street and maybe 6 AutoX events a year. Would like to be able to adjust it to go lower if possible, but I prefer a good track stance over the lowlife. Just don't know if I should go coilovers or just get shocks/springs. Not looking to spend more than $1k.

I had BC Racing BR coilovers on my e36 m3 and loved them. They came with camber plates and some more goodies, so if there is something along those lines that I can get that would be awesome, too.

I have an 09 e92 335xi and have ordered all new lemforder tierods, upper and lower control arms, new bc coil overs (still being made for my order) just had my new 19" wheels come in and waiting on new tpms sensors and tires (245/30/19) to come in. Coil overs should be in within the next 2 weeks or so. I will post a review.

Looking at the FAQ it looks like the B6 may be more appropriate for your application. If the B6 are designed for stock ride height and the stock sport springs lower 0.6" then you are well within the 30mm lowering the B6 can handle.

Down to which lowering level can the BILSTEIN B8 Sprint shock absorber be fitted?
Down to 50mm. The ideal depth for driving dynamics is however between 30mm and 40mm; any lower and the driving performance becomes poorer again, unless a major adjustment of the entire vehicle is carried out.

Down to which lowering level can I go with BILSTEIN B6 sports shock absorbers (not shortened) in conjunction with shorter springs?
Down to 30mm. That is what is typically offered for new vehicles straight from the factory. Any lower and a shock absorber with a shortened stroke has to be fitted, so that the spring tension - which ensures the required distance between the car body and the wheel - is maintained, whatever the driving situation. Otherwise the spring may slip out of its fitting and the vehicle will abruptly go out of control.

for that price range I would go with H&R , non adjustable damping but considering you have 6 events a year and you mostly see street roads, it should be a good option

So just installed my coilovers, what should I be replacing next on a 335xi , the coils are definitely firm, and the frame definitely takes more force form vibrations and impacts, how can i reduce that ? will replacing sway bars and bushings help ?

I just had B8s installed in the rear of my 2011 335d M Sport, along with Monroe upper shock mounts.

Bounciness has not been eliminated. I'm not completely pleased.

Looking at maybe a coilover set now.

Been a while and I forgot about this thread tbh. I have installed BC Coilovers, all new control arms, tierods rods, new 19" wheels with 245/35r19 Nitto Motivo and lowered the car a bit.

The ride is good but within a day or two I found myself needing to replace front c.v. axles which from everything I've read is a pretty normal wear point (114k miles) replaced with reman bmw parts and it drives very smoothly. The rebound is set just a little high but overall I am very happy with stance and surprised at ride quality considering how much lower it sits.

Is Bilstein B14 coilover good for the E92 335i?
I read that there is clunking noise and people complained about the quality of this coilover?

Julian2485 I used Cardone reman'd axles and paid about 135 or so for delivery straight to shop. You can Google cardone axles. NAPA rebrand cardone axles too, but you have to make sure they are specifically the cardone ones.

2. H&R with stock/aftermarket shocks
3. Eibach coilovers
4. H&R coilovers
4. KW 1/2/3
5. ST coilovers
6. Bilstein PSS9/10s
7. Dinan stage 1/2/3
8. Bav Autosport coils
9. BMW performance suspension
10. TC Kline coilovers

Thanks to Fraggy, we got 3 to compare but to hear more about the others would be great!

As in my previous threads, im still waiting for BMW performance to come out with something for the E92s but if nothing really comes up by this fall, im gonna get ST coils

I did KW Series 1 when my E92 had 5,000 miles on it. Set them up at the lowest ride hieght, car was slammed. Handling and body roll vastly improved, only other suspension mod at that time was non-runflat Michelin PSS tires. I later added a Quaife LSD.

Ride frankly wasnt great, due to the car being so low. Fast forward to last December, had the suspension redone with M3 parts, tie rods, trailing arms, bushings, sway bars etc... In the midst of all the work, it turns out the front shocks were shot, leaking oil and need a re-build. Rather than wait for weeks to have KW rebuild them, i replaced them with Series 2 coil overs. Raised the car back up, so she sits maybe 1/2" lower than stock. The difference is amazing. With the M3 parts the suspension is tight, and super predictable. The KW's at a more realistic height give a much more comfortable ride, and i no longer cringe every time i encounter a speed bump, or steep driveway.

I put a deposit on a set of upgraded brakes, to be installed next month. Going to shop for wheels soon, and will pretty much be done. Was shopping for a new car recently, but due to the depreciation over the 7 years I've owned my E92, the time and money put into the car, the fact I love the finicky bitch, and to tell the truth the car runs circles around 95% of the cars on the road and still looks damn good, I think I will keep her.

Have Eibach springs with yellows...first 6 months about 3 turns if I remember and seemed pretty good but later I did subframe bushings and decided to crank them another 1/2 turn and seemed better without ever bottoming in front as i could before on rough roads sections. I think its very comfortable for daily and had many ask about stance. Reasonable price for great look and good feel. Only at high speeds are springs maybe overmatched.

I thought about buying the Koni Yellows when I re-did my shocks and struts but I did not want to have to take the entire shock or strut out so I could adjust it. So, i opted for the Bilstein.

What Koni needs to do is engineer some sort of adjustment knob on top of the shock / strut that you could access thru the engine bay and or the trunk.

@x1ngxang,

I did this to my 328 E90 and I wish someone told me this info im about to tell. you when I did it.

Your E90 is old and the suspension components are worn. Including the original rubber parts that the suspension relies on.

Get new strut mounts aka strut bearings. The new part number will be thicker than the OE one on your car. You can counter the lift with the Supreme Power lowering spring perch.
Also get new rear rubber spring seats. Again, my car actually lifted as a result of the B12 kit and the new fresh rubber parts. But it looks fine and rides like a dream. B12 was the best mod that I did to the 328. Going to do the same to the 335d.

Links:
Front strut bearing: https://www.ecstuning.com/b-lemforde...SABEgLstPD_BwE amazon has them for a few bucks cheaper I think. Look for the lemforder ones.

Spring seats: https://www.ecstuning.com/b-genuine-...SABEgJYTvD_BwE

Some good info here, but still TLDR. I'm going to be upgrading all of my suspension and the biggest upgrade is with the Ohlins RT. My E90 is shy of 60K and browsing on TMS and ECS I saw front strut tower reinforcement plates, do you guys think I should go in on a set? I don't intend to lower the car as the current ride height with the worn MSport suspension is just right. Please advise since most of you seem to have gone through multiple setups.
