Probably the best 'real world' damper comparison videos on KZbin. Thank you and well done ✅

[@ViCKyN94]

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

[@garrettgiuffre7298]

Yes I'm not sure I'll go coilovers. The out of the box performed, perfect stance for the wagon, firm but have no issues with the worlds worst roads in California reminds me of the top gear African special. Apparently they have a lifetime warranty although I have never had a chance to send any in to verify the coverage of that. If it was a track car I'd consider coilovers for the adjustments but with these b8s being set up the right way they don't need adjustments. They just work the way they should perfectly. They bolt in perfectly. They ride comfortably. They make no noises. They give you no headaches. They just work and then perform work and perform perform work. Just remember to replace your hardware if it's aged. It is a McPherson strut and it is a part of your steering system. So there is bearings and bushings in that top hat that do wear. If you have 200,000 mi, it's a good idea to go ahead and do that. If you're going to put new suspension in and use a spring compressor for god sakes don't die

[@mmmadog]

The b8 are made for lowered cars. The b6 is for stock springs.

[@makosasimakis118]

Usually Bilstein B6 are fitted with Eibach pro kit black lowering springs

[@Karl_Kampfwagen]

My Touring wagon E46 has the B8 lowering kit from factory, and I'm going to switch to the taller stock B4/B6 suspension... Lowered, I can barely take on speed bumps, railroad crossings, etc. 🤦 Feels great on smooth roads, but I need the clearance. Good to know they're almost identical, aside from height

[@workingmanaudio2754]

He installed B6 and keeps misspeaking.

[@MrNice_]

B12 complete suspensions (sport AND Pro Line) always consist of B8 + springs (Eibach black/red). He explains it correctly. Buying a B12 is identical to 4x B8+Springs.

[@3dScience_uk]

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.

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.

What you recommend to me i have e46 on einbach pro kit, B6 or B8?

[@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

[@omega_profile1]

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.

[@OEMplusRESTO]

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. Im a bit worries the b4’s wont last long though. Maybe 50k before needing replacement. Please let me know how you like them and if you have any annoyamces with them once installed:)

[@kennmart1]

This is great timing am getting ready to order up some shocks for my 330ci.

[@OEMplusRESTO]

Happy i could help

[@MrNice_]

A tip: if you tighten the rear shock absorbers on the lift with the wheels hanging, the rubber bearing on the shock absorber is fixed in this atypical position and permanently twisted to the maximum in everyday use. So just screw in the bolt and either lower the car completely and tighten it on the ground (uncomfortable) or lift the axle to the normal position with a gearbox jack.

[@OEMplusRESTO]

Thank you for the tip. I dont know about all shocks but for the b6/8’s it doesnt change anything if theyre loaded or unloaded due to the bushing type used:)

[@pete9501]

Phew, fitting B4s to a little Ford KA Mk2 tomorrow morning. Nice to hear I bought the right ones.

[@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)

[@jancobeintema6226]

Suspension parts with rubber bushings should be torqued with the car on the ground.

[@siedlisko-zla]

Not all of them.

[@ozymandias7940]

I have a 2013 Mercedes C63 (W204) and it had the original suspension in it. So I did some research and put a set of Eibach springs & Bilstein B8 shocks all round. Well... Honestly, you'd best keep the number of a good chiropractor on speed dial, I mean it was absolutely brutal. Basically felt like there wasn't any suspension in it at all. Granted, on highways with smooth surface it was awesome, but 99% of the time it is on suburban streets that are just horrible. Anyway, put up with it for about 3mths, ripped out the B8's and replaced them with B4's. Much more tolerable.

[@OEMplusRESTO]

For a cruiser like that id imagine the stock suspension would be very compliant, im which case, the b8’s will be much harsher than for instamce on a e46 330ci

[@siedlisko-zla]

That's the very good point with the limits of the tyres vs limits of the suspension!

[@OEMplusRESTO]

Thank you. Upcoming video will find the limits once again. Thanks for the input:-)

[@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.

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.

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.

[@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.

Now I have a B8 + Eibach pro-kit and it is not bad honestly. Only downside for me is when you are cruising on the highway the car now feels much more imperfect and it is not going so smooth again.

[@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.

B4 is not more safe. The B8 was able to let you know that your tires are poor. Replace the tires and enjoy a car that utilize the full potential of the shocks.

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.

I ordered Bilstein shock absorbers for my E60, I have an M chassis, so I chose the Bilstein shock absorbers adapted for M chassis and I would also like to change the springs but I cannot find any suitable for the M chassis of this brand. Should I then buy M springs from another brand or Bilstein springs but not suitable for M chassis?

[@OEMplusRESTO]

Im no expert on E60's though i love them too. But id go for a m chassis spring as the normal rideheight will have to be compressed alot to fit on a (what i assume) is a shorter M chassis shock. But if the old springs arent rusty or looks to be liek theyre about to break id reuse them. Springs are almost non service items if rust doesnt get to them first

Theyre both for mtech. One ends in 31 and the other in 48 in part numbers.

[@B.Zh.s]

Here is my 800 like 😄 Is the B8 a lot more stiff compare with 330CI stock *on the rear? Currently on my 330CI sits on coilovers ( don't remember the brand )... it's fine on the front but too soft on the rear, I have put some eibach spings on the rear, but still too soft on speed bumps ( it feels almost like boat )... So I'm wondering should I go for B8 just on the rear, want to have more sporty feel but still some comfort ( it's dally driver ) don't want to be super stiff when you go over a speed bump to hear all the interior plastic cracking 😅

[@OEMplusRESTO]

Hi. From your description id say the b8/b6 has a good chance of giving that bit extra firmness. I havent noticed mine being floaty at least. Hope it works out for you:)

[@B.Zh.s]

@@OEMplusRESTO Alright, thanks! I have ordered 2x B8 for the rear… will give it a try when I have them. Many people “complain” when installing B8 actually raises the car, did you notice something like that?

[@OEMplusRESTO]

@B.Zh.s no. Havent experienced that ever. Ive gone through 5-6different springs and 4-5shocks on this car and ive only ever seen the springs determine the rideheight

[@OEMplusRESTO]

Btw what wheels are you running? And how are your bushings in the rear. Big sidewall tires and worn bushings can be your issue as well.

[@B.Zh.s]

@@OEMplusRESTO I think 90% is from the current coilovers - old and worn 😄 I have double check for the brand... they are not even branded 😂 most likely cheap knockoff - will replace it completely in the future. I found some eibach pro rear springs lying around swapped and immediately was able to tell the difference ( still too soft though ) will pair those with B8 a will see ... Rear bushings are OK (not perfect) I do have them all new as well ( to rebuild everything on the rear when I have more time ) tires Im on 255/35/18 rear, so no big sidewall. 🙃

Im looking for shocks and apeings for my e61 525d. I just want something that doesnt feel like a boat in the swings. Do you have anything you recommend?

[@OEMplusRESTO]

Id say b12 just to be sure.. or b6 woth the original springs if you want to do it cheaper and without lowering

[@PedrizzlyBear]

How would you compare the ap coilovers you had previously to the B8's? I bought the car with the coilovers and im curious if it's worth the upgrade

[@OEMplusRESTO]

It wouldnt be a fair comparison because they were old, and one wad leaking. But theyre definitely stiffer than the b8’s from my experiemce.. the b8’s arent that stiff once you compare them to the oe mtech ones. Compared to non mtech ones everythings quite stiff lol

[@namir1782]

hi man i own an old 330d 346. my shock absorbers are loosing oil and my bushings are almost gone although i changed both front arms less than 2 years ago. what do you recommend me for an affordable and durable replacement. can i change just the shock and keep the old springs? also can i just change the bushings of the front arm wout changing the whole arm? i am thinking about the powerflex just for the sake of durability also i dont mind a sportier feel thanks in advance

[@OEMplusRESTO]

Yes. Springs should be re-usable. So should the arm with a new bushing. The poly ones are so easy to install and uninstall that id recommend to anyone who want something “cheap” and easy

Hello and thanks for excellent video. I am considering shock replacement for my 2004 330CI M-Sport 2, 142.000kilometers. EU-version. In my mind i think i would like to keep it in standard ride height, as the car is 100% original. M-sport 2 ride height works for me just fine. Do you agree, that Bilstein B4 M-sport shock version would be ideal replacement for old tired shocks? I dont do track driving or anything like that it is automatic cruising machine for summer season. Do you have part numbers for M-sport 2 package Bilstein B4 shocks, front+rear? Best regards from Finland.

[@OEMplusRESTO]

Hi. Sounds like a lovely car. You can find the part numbers in the description. They sre really good so can only recommend.

[@oncall3570]

I have B4 and can confirm them excellent for the money. No need to change the springs unless they break, esp. as factory setting on Cis in many markets is 'Sport setting'/low-slung height (for e46 this is 15mm lower than limousine/touring/compact e46). Never seen a Ci with i factory 'limousine' height.

Thanks for the insight. Rideheight remained unchanged due to using the same springs but i’ll try and do so next time. Take before/after photos Right now im working on a video of steering couplers. Worn vs oe vs solid.
