Hi guys,

I`m after this kit (https://www.getbmwparts.com/partloca...catalogid=4462)

getbmwparts can offer this but they don`t sell to people outside US. To buy from them, I need to organise cross-boarder shipping by myself. Calculated the rate from FedEX, it is about 500USD wtf.. not included tax yet. The kit is just 1200USD.

Any local vendors can order this?

Thanks a lot,Eric

Just get Bilstein B12 prokit, BMW performance suspension is only a slight upgrade. B12 comes with better monotube dampers and is cheaper.

I've ordered from getbmwparts a couple of times and used https://shopmate.auspost.com.au

Wasn't too bad.

Thanks vtl , I have read some threads saying that B12 is too harsh.

The thing I don`t like Msports suspension is, its feels harsh on rough surface, has nearly no filtration of these small but endless vibrations. This is neither sporty nor comfortable. Now the tricky thing is when you need support during the heavy steering, it suddenly becomes soft For example, during my daily commute I have to pass through a rough road under 50km/h, in the end it is connected to a roundabout. Before roundabout car feels too harsh, in the roundabout cars feels too soft.

So I want a suspension which can at least weaken these annoying vibrations but meanwhile provides a good support during steering. People who have installed Performance suspension wrote this kind of review. That`s why I am in favour of it.


PS: I used Bridgestone S001, a lot better than previous RE050a. May change to non-RFT in future also.

Use hopshopgo. Legit. Used them for many things and they are cheap.

B12 Pro kit is less harsh than the b12 sports line I've got the B12 pro kit on mine at the moment. Coming off the m sports this is way better.

If you're going to upgrade your suspension, do it right. BMW Performance kit is only a slight upgrade above the stock M sport suspension.

The harshness you're complaining about is most definitely caused by the crappy run-flat tyres. Because they have much stiffer sidewalls compared to normal tyres (to support the tyre without air in it, in the case of a puncture), and they transmit much more road harness and noise inside the cabin.

Once you get rid of the run-craps tyres, and put normal tyres on, these cars actually feel silky smooth, even on Melbourne's shitty asphalt.

I've got the Bilstein B8 shocks and Eibach Sportline springs, same shocks that come in the kit vtl recommended, but slightly lower springs. I find this setup to be very good, it provides the best balance between comfort and sportiness in my opinion.

Other suspension/handling mods you should consider:
1- E92 M3 front sway bar
2- E92 M3 rear sway bar (only install in conjunction with a LSD)
3- LSD
4- Front Dinan camber plates
5- Rear Subframe Bushes (Nolathane, Aussie made and cost roughly $150)
6- M3 front and rear control arms
7- M3 front strut brace

(6 & 7 are not very important, but if you have cash to spare, might as well do them)

After that, your E92 handling is done and dusted! It will feel like a gokart at this stage.

P.s. Bilstein is German based, and they've been making car suspension components since 1927 for many car manufacturers. Most Porsche cup cars run full Bilstein suspension setups. I'd definitely trust them over BMW Performance line of products when it comes to suspension.

Also,

Another options to consider, would be Koni Yellows Sport shocks, I have a mate running them on his Evo and finds them brilliant. I think Socket got them on his E92 335i too. I heard from multiple sources that the Koni Yellows are slightly softer then Bilstein B8. The Koni are also adjustable, so you can reduce the stiffness on them if you find them to be too stiff.

Some folks run coilovers, but considering you're worried about harshness, I'd avoid. Imo, unless a car is driven a lot on the track and is not used as a daily, coilovers are probably too stiff for public roads.

Pitos is correct, Im running koni yellow sports shocks. No complaints here

Thanks mate, that`s a lot useful tips . I may start from tyres and then suspension setup so I can feel how they play on their own in handling

Shall I upgrade 26.5mm front sway bar together with B8/B12 setup? I see Performance suspension setup comes with a 26.5mm front sway bar.

I prefer to get rid of all of the understeer tendency and instead upgrade the rear swaybar to an E93 M-Sport one and do M3 front lower control arms and M3 rear subframe bushes. Works an absolute treat for me. I won't be changing the front swaybar at all.

Shopmate`s the maximum accepted weight is 22kg. My parcel is 30kg

[bradsm87]

FCPEuro are usually on the pricier side but the shipping is DIRT cheap. Worth checking them out.

Front sway bar makes a huge difference in front end grip at the limit. I was quite surprised at the difference it made to be honest. These cars lose (or gain depending on how you want to look at it) a ridiculous amount of camber as the suspension compresses.

It does make the car ride harsher though.

To the OP,

If it's comfort you are after go for bmw perf springs with a good set of dampers (koni yellows or bilsteins), keep the standard standard sway bars, ditch the runflats and lower your tyre pressures to around 34-36psi. You'll gain a fair bit of performance with upgraded subframe bushes, you'll also lose the floaty feeling in the rear end but there is added harshness which IMO is totally worth it but may not be for you.

Upgrading the teeny tiny rear swaybar also helps reduce bodyroll (both front and rear), with the rear taking up more of an even share of the work. M3 front control arms and removing the alignment pins in the front get the camber, and to a lesser extent, the caster better, both greatly helping front outside tyre contact patch when cornering. I find this balance best as well as the added comfort compared to upgraded front swaybar.

The stock rear swaybar is made so tiny to reduce single-pegging with the open centre diff. LSD is the proper way to fix this.

it's all a fine balancing act. I wouldn't want anything firmer then the e92 bar. which means that the e92 bar is the only real option, all the aftermarket bars are way too firm imo.

I ran with dinan camber plates for a year before putting the sway - which wasn't on my plan of mods but vtl found me one cheap and convinced me to install it.

I have to say it's probably my favourite mod especially when considered from a $$ to performance stand point.

i guess I'm in a similar situation to you now where I'm happy with the car and don't want to sacrifice any more comfort. nobody really does the rear bar but i do agree it does seem tiny especially with the upgraded front.

I think that the front swaybar is much more commonly upgraded because if done by itself with no other changes, the bigger front makes a more profound difference in bodyroll and if front camber is still stock, reducing as much bodyroll as possible is pretty important. Another reason is that the front one is MUCH easier to install. The rear works well as part of a number of other supporting mods like LSD, good shocks and better front camber, but may not improve performance that much just by itself.

[vtl]

One thing to consider is your chassis. E82 suffers from terminal understeer once you get beyone a certain amount of body roll. The camber on the MacPherson strut front suspension decreases once you get beyond a certain amount of compression.

I did the front sway and it increased understeer slightly up to the limit, then you get a bucket load of extra grip you didn't have before as the body roll has been reduced.

On an e82, the e92 m3 26.5mm bar is sufficient. Anything more will increase understeer. On an e92 335i you can do either e92 m3 bar or e93 m3 bar, both would work fine. On an e93 335i id suggest going an e93 m3 front sway for the heavier car.

On my car I feel it could benefit from a slightly thicker rear bar, stock is 12mm and going to 15mm could be the answer to balancing it out with the E92 M3 bar I am running.

I have fitted an e93 m3 front sway and an e92 m3 rear sway to an e93 335i with an open diff and don't notice any issues with traction or it being tail happy. Install is a real pain with the subframe having to be dropped almost all the way to the floor, the thicker bar is very difficult to install due to being extremely close to the suspension links.

True but you did just fine installing the M3 rear to SPCGRY Yodes

[DOCTOR.Y]

The other day I was in Stu`s E92 M3 (BMR1). That car comes with YOKOHAMA AD08R tyres, we drove on some rough asphalt road and it did feel quite comfortable and quiet. I was instantly convinced that how crappy RFT are... I should realise this early but kept telling myself, it is bad but not too much. After getting out of that M3, I determined to replace these RFTs with PSS I`ll see how it goes.

PS: In this thread I can see a lot valuable advices, also I can see different people have different combos. It is a lot knowledge to me at this stage, I appreciate everyone`s words, although I end up with Performance suspension. It takes time to experience the process of modification and adsorb these knowledge. Sometimes I opened this thread again and looked at these advices, think about them and also think about my current feeling about the car. I`ll see how it feels after changing from S001 to PSS and decide what to do next
