The SHOCKING Truth - Bilstein B4 vs B8 (B12) E46 330ci

Testing the differences between the Bilstein B4 Mtech version vs Bilstein B8 shocks. Both using the same eibach springs that would make the B8 shocks into the B12 pro package then. The same goes for b6 shocks. Theyre identical to b8 shocks but for standard rideheight instead

Im running a set of B8 on my 330 sedan. It is definitely as stiff as adjustables, especially over pot holes. But it makes the car feel very planted on the highway/freeway and during canyon/mountain runs. Man i love your ride, your undercarriage is so clean

[@OEMplusRESTO]

Thanks for the input. The b8 (b12) feels great on the highway no doubt. But the b4 did as well imo. Maybe the b12 slightly edges it out but i think it could be placebo. And thank you for the kind words. I atill need to do the front but will remove the engine/trans when i do the rest

[@spencerhulme1203]

I really appreciate you taking the time and showing the comparisons between the B4, B6 and B8's as i need to change the ones on my E92 320D m sport Highline. The suspension was already lowered from Factory and originally fitted with B4's as OEM the SE models with Sachs, i changed the rear shocks in 2018 the differences were night and day but having some money to spare i want the car to feel good again, so i was thinking about installing coil overs the BC racing until i seen many reviews of negativity for street driving, so i think i am going to get the B8's after your experiences (thank you so much) and for showing how to install 💯 Professional.

[@3dScience8]

Guys plz read this: The biggest difference between B8 and B4s is the LONGEVITY. One of my front B4s was shot after 20.000miles/ 32.000km (1 1/2 years of use). The B8 shocks/struts last MUCH longer. B8 shocks/struts and OEM msport springs is a very very good combination. Eibach sportkit springs and B8 shocks/struts will be a bit on the harsh side. In any case the tyres are very important/ more important than B8 vs B4s. In normal temperatures (not very cold) try Michelin Pilot Sport 4 or 5 or the very very good Falken Azenis FK 510 / 520. These tyres will last less than others but the grip they provide is amazing.

Happy i could help

[@HumbleBearcat]

I had my wife's 2010 Golf struts replaced with B4 and they are excellent. The Bilstein website says it's about 10% stiffer, I think maybe 15-20%. The motions is quicker but much smoother. When you are going over speed bumps at low speeds; it feels very compliant but will firm up when you are driving at higher speeds. The price is very good also. I just placed an order for a set of B4 on my 2018 Q5. Can't wait to have them on my car.

[@OEMplusRESTO]

Thank you for the insight. I think for vag cars you can sometimes do it cheaper with sachs kits on ebay but you cant really go wrong with billies either:)

[@LocalAutist]

The perceived 15-20 percent is likelt because shocks get mushy and "soft" after a while

[@SlowCarsFastSFV]

B4/B6 are for OEM ride heights or moderate drops with lowering springs. The B8s are for use on cars lowered 30mm+. B12s are coilovers.

[@OEMplusRESTO]

B12 is b8 shocks with eibach springs. B14 and b16 are the coilovers

[@SlowCarsFastSFV]

@OEMplusRESTO It varies by car. For my Mazda, the B12s are coils. They don't offer the B14 or B16 for it. I have B8s with H&R springs that work well.

What Mazda? Did you trim the rear bump stops when installing the B8? Or did you keep the OEM ones?

[@SlowCarsFastSFV]

@@stefanosilimbani9285 Depends on the springs, but B8s on my car are intended for 30mm drops or more. You'd need to trim (top portion) or find a suitable aftermarket option.

Thank you mate! That BMW underside looks like new! I just ordered the B4 because there is no more gas in my OEM shocks and it started handling dangerously. In the NL we have so many speed bumps on the roads that any cheap suspension can wear out fast.

Thank you for the compliment. Im honestly considering going back to b4’s again but want to wait until i hve compared the b8’s to the b14’s as it will be easier to compare them like that.

[@sonic_attack]

Running B8 and H&R sport/sport springs in my e39. Loving it so far. I don’t find it a bad ride given the roads around my area here in Auckland New Zealand are pretty poor, car feels very planted and level through hard cornering. Interestingly, the combo I have didn’t require spring compressor to stitch together. Used new spring pads and plates with all new hardware and they just slotted together only needing a press with the palm of my hand to get thread started with top nut. I probably have different expectations but I can see and feel the added value in the B8’s.

[@OEMplusRESTO]

Its aleays nice when theyre easy to assemble:) which e39 if i may ask. I have had a 530i and a m5.. oddly i miss the 530i the most!

[@sonic_attack]

@@OEMplusRESTO 530i. The facelift Msport variant(2001) I’ve had it around 5 years and probably neglected it for most of that time if I’m honest. I decided to take a good look at it 6 months or so ago and came to realise it’s actually a really well constructed vehicle and worth my time putting some effort into it, hence new suspension when I saw a leaking front shock. I was going to buy another e34 540i but decided to just refresh everything on the 39 because it’s been such a reliable car. I’ve replaced the entire cooling system over the 5 years as parts broke but apart from oil changes it’s had no other maintenance, but been used daily.

[@PaleD]

The rear shock bottom mounting bolt, should be torqued with the suspension loaded. Otherwise it all looks good. Bouncing is more due to the spring rates, a bit less so about the dampers. Monotube is better overall. Most ppl will get the spring rates wrong, and even the manufacturers sell spring rates that are not suited for the car. Look up "flat ride" harmonics.

[@OEMplusRESTO]

Thanks for making me aware of it. Monotube vs twintube there are advantages to both imo. And i think youre right about sprinrates. My omd e36 m3 i tried 3 different sets of oe springs before buying eibachs for ir. Not only did i not loose any comfort, it handled better too. And looked better(though that is subjective)

How long do you plan to keep the car? The last time i was in chicago the roads seemed decent? I was only in and around the airport area snd 15mimuted away from the airport area. If thats the case you could definitely get away with a lowered b8 with eibachs (b12 package)

@@christophervillarrealdelao1177 the b6 with eibachs will be sligtly more comfortable than the b8/hr setup. Shocks are the same valving so it will come down to the springs. And the difference isnt huge. But its there. And if the roads are full of potholes id feel better about the slightly higer rideheight of eibachs vs hr’s

[@bluewhitecars]

I didn't quite understand that. Have you now fitted B6 at the front and B8 at the rear? The B4 damper is the same as the OE damper. It is neither better nor worse. From the B6 damper onwards, Bilstein uses better and higher quality technology, which is identical from the B6 to the B16, except that from the B14 onwards it is coilover suspension. I have installed the complete B12 suspension in my BMW 650i and I can say from my own experience that the car drives much better, quieter and more stable at top speed (German Autobahn) than in comparison to the standard suspension. Basically, I don't believe in lowering springs on standard dampers. On the B12, the dampers and springs are matched to each other (B8 = shortened B6).

[@OEMplusRESTO]

Hi. B8 front, b6 rear. I agree the b4 mtech is just what the car came equipped with. Likely could habe been sachs as well and i would have reached the same result.

[@jeffhammond8969]

Why did you put bump stops on the B6? They have internal bump stops so the externally ones are unnecessary.

[@OEMplusRESTO]

Only in the front. The rears still meed them

Im just a bit weird here but youre the first one that notices it. Before wrencing on bmw i never used torque wrenches and did everything but headbolts by hand feel.

That is a steal!! Congrats. Having done more miles on them since video i really like them too. They soften up a bit after a few hundred miles too

[@edd7397]

Monotube shocks are always less comfortable on small bumps due to their design.

[@OEMplusRESTO]

I did not know that. Thank you

[@vollcare4076]

Due to their internal gas pressure

[@martsmarts]

I have the same shocks. Are these shocks rebuildable?

[@OEMplusRESTO]

I dont think they are no. Maybe by bilstein but i dont think mere mortals like me have the tools and parts access tp do so

[@makosasimakis118]

@@OEMplusRESTO from Bilstein B6 front shock absorbers all the way to the most expensive , yes they are rebuildable. Only the fronts if i am not mistaken

[@MegaHollywood1971]

Here are the facts: The B4s felt as if they were "dancing" because, they were fitted with Lowering Springs. Thus, the shock was already compressed. The B8s (on the other hand) felt more composed because, the tube is shorter - thus, not compressing prematurely when on lowering springs. In order to make a comparison - each set-up needs to be tested under the conditions they are designed for. If anyone wants a more "Track" capable car, then B8s and lowering springs are your option. If you wish to refresh your suspension and keep the stock ride height, then B4s do provide a slight dampening advantage over stocks. B8's will ride hard, so if you daily - then be prepared for a jolting ride.

[@workingmanaudio2754]

He installed B6. He keeps calling them B8s because the valving the is the same. In the beginning of the video he stated that he went with the B6 because the shaft was the same as the B4 and the spring was mild drop.

i have the b8 in the eibach package (B12) and i dont like them.

[@shueibdahir]

Thank you for this information but I have some feedback. While the video was good and I found the information I was looking for, this video could've been 70% shorter than it had to be. The installation part could've been cut much much shorter. And when you started driving the car you could've said the conclusion first (tldr) and then start talking about the differences. Whatever the case, thank you for this and i hope your youtube takes off sir

what’s the difference between b8 and b12?

The b12 comes with eibach springs. B8 are just shocks

[@ducwolf]

I Wonder why You fasten the dampers while the car is still on the Lifting platform ???? Your chassis Must be under massive tension. No wonder that the dampers are so stiff You worked wrong !!!

[@OEMplusRESTO]

It doesnt matter for these shocks. For bushings yes. But i dont torque down any bushings during the process
