The Bilstein is a great bit of kit Get the rest of your install pics up, and also pics of the car after!!

I've just done the same as you're doing now - here's the link to an in-depth review I've posted about the Bilstein B16/PSS10 Ride Control System, as installed on my E92 335i

very nice..

[NoMods]

that is pure sex - how much does it improve handling.

any skidpad comparisons?

[marconi118]

Could you post some pics of the front upper bearing? I think it reuses the original spring plate and bearing.

The problem is that the 335i oem bearing is in soft rubber bushing that gives poor handling. In fact the E92 M3 has a complete different bearing+plate made of Aluminium (see on realoem.com). It is impossible to use this aluminium bearing+plate on the 335i beacuse the diameter of the 335i spring is bigger.
So whe should use M3 front springs with the 335 bilstein shock + M3 bearing

Finally, here is my LONG (sorry) subjective review of the B16 Bilstein Ridecontrol suspension for the e90 335.

I have to start by thanking Mike at **********s for making the buying experience an easy one with their advice and guidance on the product, shipping options, charges and best of all fast and efficient delivery. The Bilstein package was the largest order I ever placed and I was obviously worried about possible damage to the product crossing the Atlantic. It was shipped directly from Bilstein US in perfect condition.

I researched the various suspensions from the different brands as well as the Bilstein range for the e90 and searched the bimmerpost reviews. The PSS10/TEIN/H&R/KW/Eibach looked great with mostly good reviews. But I settled for the B16 ridecontrol because of the convenience of the in cabin dampening control feature and because it would be another gadget in my performance arsenal. The bilstein advert that grabbed my attension read like a TV commercial and what a sucker for adverts I am:

"Would you like to be able to adjust the ride of your 3 series without ever stepping outside of your car? If so, the Bilstein B16 Electronic Ride Control Adjustable Coil Over System is for you. The Bilstein B16 Adjustable Coil Overs allows for cockpit adjustment saving you the hassle of manually adjusting your coil-overs. With the flick of a switch you can take your BMW from a normal ride used for everyday driving to; sport mode to firm up the suspension and allow for improved handling.

Advantages at a glance:

• Bilstein mono-tube/inverted technology for front and rear (whatever this means)
• Immediate damping force selection provided by a cockpit mounted push-button
• Bilstein Nurburgring-Nordschleife road tested and tuned
• Good ride comfort coupled with an agressive sport option suspension
• Great lowered appearance-fully adjustable ride height - and German TUV approved
• Bilstein warranty

The Bilstein Adjustable Coil-overs are perfect for any car that is both daily driven, and sees aggressive street driving/track use. Since the coil-over is height adjustable this allows you to choose exactly how low you want your car to sit. The Bilstein B16 system puts you in complete control, providing the kind of precise suspension tuning formerly available only on race cars. From a weekend of track use, to daily driving, this system provides perfect handling when you want it."

So, the package arrived and I was impressed with the quality of the springs, shocks and all the parts that came with it.

Made an appointment with my local BMW dealer to discuss the implications on my existing warranty if I were to install the Bilstein kit and the cost of installation. Essentially, my warranty on the old suspension kit was deleted (only) but I received a two year warranty for labour and installation of the Bilstein kit excluding the Bilstein components. But this did not posed a problem for me because the Bilstein components/kit comes with its own warranty that lasts as long as the car remains in the possession of the original owner that purchased the suspension kit. (of course there are some warranty exclusions - such as do not race with it!!!hee..heee..)
If I were to reinstall the old BMW suspension (to be reinstalled by the BMW dealer) the warranty on the old system would be restored. Fine with me.

So, after 8 hours over two days the suspension was installed by the dealer. And what a great job they did especially with the wiring and the in cabin mounting of the control unit. The wiring is completely independent from the BMW car wiring and the only link is connecting the Bilstein wires to the battery terminal for powering up the Bilstein control unit. The wiring runs from the 4 shocks on the inside of the car (under the carpet on the sides) to the front of the car near the BMW ECU area where it plugs into its own Bilstein ECU control unit. The only difficulty we had with the wiring install was the fact that the wires of the front shocks come out at the bottom of the shocks which made it more difficult to guide safely upwards to the bonnet area without twisting and forming crinkles unlike the rear shock wires that come out at the top and was easily guided through the existing holes in the body of the car. We discussed the various heights-the kit is fully height adjustable - a 15mm drop was my preference but we settled for 20mm. On the 17' and 18 inch wheels I am sure one can go even lower.

The old suspension was the sport pack version. With the Bilstein kit installed the car had a lowered stance front and rear but not excessively low. I could push one finger and a bit between the rear tire and fender. But the embarrasing stock gap was gone - car appeared streamlined, low and aggressive. My test drive after the install before the wheel alignment was done was a nervous and tensed affair (right in the stomach) expecting to be surprised or experiencing the car to bottom out or to be dissapointed with a very expensive purchase. But the test drive was spoilt by the rubbing of the rear tires (225/35/19 front and 255/30/19 rear) against the fender walls whenever we hit a dip even a slight dip. So we put the standard wheels and tires back on (225/45/17 front and 255/40/17 rear) and yippee off we went!! No rubbing or thumping.

After a short drive the difference in improved handling and ride comfort could be felt immediately. It was a tad softer than the standard suspension. I pressed the sport switch or push-button and wow! That little switch/button was like hitting the G-spot of the car.

Okay, the description for this round switch/button is a misnomer. When the car is started the suspension is in normal mode (the default mode) but normal mode is actually sport mode, so I will refer to normal mode as sport mode. When you press the switch/button the car is in sport mode but it is actually race mode, so I will refer to it as race mode. Sport and race mode. Sport is the default mode and race mode is when you press the switch. Okay? The switch button emits a pretty blue light when the car is started and when pressed it "clicks" and a tiny spot in the middle of the round button also lits up in bright blue to tell you you are in race mode. I am glad the switch is hidden in the ashtray because at night the blue light is too intrusive and sharp on my eyes and better to close the ashtray lid at night - during the day it is pretty and perfect. The first few days I had to take my eyes of the road to find the switch but I am getting used to its location with less fiddling.

After two days I had the fenders rolled in to get rid of the squealing and rubbing and put the 19' wheels back on.

It is hard to believe that the old stock BMW suspension looks so crappy and ugly yet giving us the "ultimate driving experience" and is the benchmark in a great handling car - the stock suspension is comfortable and reassuring, as we all know, owning a bmw. If you drivie a BMW on the track with standard suspension you know how much abuse it can take on the track without falling out underneath you - it just goes assuringly from the one corner with body roll and all to the next bend. You will never push the car on its stock suspension to its true limits in real world driving conditions/situations - I don't think so. The Bilstein kit is better in the comfort stakes to the stock suspension even if it is just; but it is in the handling that the B16 ridecontrol is far more convincing and improved substantially to the stock setup. I hope I am not ambiguous about this point.

Back to that switch: the race mode is something else altogether - it is simply brilliant!

"The kit features an electronic control unit that senses road characteristics and G-loads and makes shock valving changes in a millisecond!"

Race mode is an agressive and immediate dampening force selection that seriously tightens up the springs and shocks. It does NOT lower the car but gives the feeling and appearance of being further lowered. Some of the early reviews I read about the B16 system talks about the race mode being too soft for track use and others said it feels like the car was running "on rails" and I think the latter is an apt description for what happens in race mode. I think (my personal opinion) it eliminates the need for further under chassis braces and sway bars - the car is thoroughly glued to the road. No matter how hard you push it in the corners or bends. Look, I am not an expert in all this technical suspension jargon but the experience on the road is simply amazing. I had the opportunity to have fun driving through the challenging Bainskloof mountain pass and remain impressed with the capabilities of the system. You can switch from race to sport so quickly when the road surface worsens to get it back in comfort (sport) mode. I reckon the suspension will get even better over time once settled in.

Crossing road humps in shopping centre parking lots was clear and fine and no need to turn the car sideways to go over them. Just gently cross them as usual.

Another surprise is the average fuel consumption is down from 12.8 litres per/100km/phour to 11.6 litres per/100km/phour consistently for my urban driving cycle! Is this due to the lower stance of the car, better aerodynamics and less drag? Maybe, since this is the only way to explain the drop in fuel consumption.

The car also "feels" quicker and lighter...If someone can identify with this please chime in. Or is it just my imagination? Surely a car that drives, handles and turns better should perform better overall and thus translates into better sprint times?! Even, if it is marginal?

There it is...fire away...

The B16 ride control is the electronic version of the popular PSS10 suspension and based on the same platform. You can't go wrong with either.

Okay, will get pic with the next lift, probably this saturday.

Handling is dramatically improved. The Track is not too far from me but to pay just to use the skidpan is a fortune - perhaps one day.

I've just done the same as you're doing now - here's the link to an in-depth review I've posted about the Bilstein B16/PSS10 Ride Control System, as installed on my E92 335i
Great review indeed!
Oh yea, and more info on the ride control would be great.
Stessdoc..I tried my best to cover as much of my experience in the review. A bit long but what the heck. thanks for coming on line man. And you know whom to contact in Cape Town when you visit - just ask for the exclusive M club or the biturbo guys...

so its just an aftermarket sport button I think it lowers it too, but i dunno
The elctronic ridecontrol is part and parcel of the suspension system "it is not an aftermarket fit" like the TEIN electronic system that can be seperated from the suspension.

Hi Imran
I followed your story in the BMW performance mag. Thanks for the input and support. You were right it is a great system!

E92Fan I read your review before posting and felt that you have said it all about the B16 suspension and that I concur whole heartedly with your review. Great pictures too! Thanks.

[Rooster335i]

Very nice. Quick question, why didn't you bring the car up a little to avoid fender rolling? Can you post pics of car after installation?

Thanks. Good question. We raised it to 15mm to see if we could avoid the rubbing and it worked for one person/driver in the car. But when I asked two guys to sit in the back the rub returned on the left rear fender. So we decided to roll the fenders once and for all and then lowered it back to 20mm. The height difference between 15mm & 20mm was really not so obvious unless you knew what to look at. But the rolling in of the fender was really professionally done - very hard to see the difference from the outside and got it nicely painted as well.

I hope to do some pics of the car over the weekend.

Incidentally, how come you needed to roll the fenders? Are you running aftermarket wheels with a wider offset ? I'm on 19" Style 230, and 265 section rear tyres, and they're not even close to rubbing even with two guys in the back

[645Nm]

So after many Ks with the Bilsteins and the rear fenders rolled in, I still got fender rubbing with heavier passengers in the car but with only myself it was okay unless I hit a really bad spot. But I also found the 19s with RFTs a bit too hard. I can get use to it but the family sentiment won. The stock 17s wheels look small but are really comfortable and no rubbing at all with 5 passengers. I am back on the 17s. The only solution for me to get rid of the thumping completely on the 19s if I want to use it again is to raise the suspension or flare the arches of the rear fenders and at this stage I am not sure I want to raise the car and loose the "look" or flare the fenders.

The brilliant handling of the car continue to amaze me!

Here are some of the pics of the car with 19' and the stock 17s. Needed to wait for the non rainy days to take some pics.

Man, your question is the riddle that has puzzled me for a very long time. I discussed your question with some e90 guys today and we have many theories. I am including two pictures of the same wheels and tires on my 335 2007 model with H&R race springs with stock shocks - you can see how extremely low the car sits (lower then the bilsteins) - now will you believe me if I say there was no rubbing on this car or fenders rolled in?

I think it has something to do with the wider track on the updated 335 model - but I am not venturing an answer - kind of like the mystery - makes a nice discussion point when the Biturbo guys get together.

Thanks for the very, very generous and positive feedback. Appreciate it tremendously. You forgot to mention you have some seriously good driving skills. I was looking at the video we made where you passed some large trucks and you simply hammered the 335 passed them with the oncoming traffic flickering their lights in panic. I followed behind you but backed off when i saw the convoy of trucks...i think i said something like "oh shit" on the video as you zipped passed them...glad it wasn't my last words.

Thanks for taking care of my treasure while you took on the mountain pass. Hope to meet up at the Ring next time with e92fan as well...

WOW! He took a borrowed car and passed a convoy of trucks with oncoming traffic clearly within sight?!!! That's balls on his part, or as you say he's a great driver and clearly had the confidence he could pull it off. Very trusting on your part as well!

Good reviews from both of you, too! I commend you both.

One question, in Bilstein Normal/Sport mode, as opposed to Bilstein Sport/Race mode, you say that the car has improved handling while ALSO being softer than the OEM-sport. What exactly does that mean?

To me softer would mean there's more roll, but you say "improved handling." That's confusing to me. Could you elaborate a bit? I have OEM-sport and wouldn't want anything softer for my daily driver. If anything OEM-sport is too soft in my opinion. So if this Bilstein set-up is softer I might have to eliminate it as an option.
