Bought two sets of PFR5-419 from UK- for 118i and for mine. Alltogether EUR 122. The labour for installation of those will cost almost nothing.
Will keep the front M3 bushings for future if will change to E92.

Also ordered TRW M3 lower wishbones.
Examined and compaired the photos- hope, they will be equal to BMW OEM ones, as the price 2,5 less is a serious difference. The TRW ones have the ///M sign melted off. So the aluminium part is the same, as OEM is manufactured by TRW. The only thing to hope- they do not use some cheaper materials for the bushings.

The xenon-light regulator arm added to the order as well.

Hope they work out. You still have to drop the sub-frame to install? Correct?

Can you provide a link for the store? Does TRW state that they are aluminum/same material as ///M?

Yes, the subframe should be dropped a little to get there.

Will try to find a link for you- it is easy to find, if you use the BMW part number for searchn it is 3110 228 .... something.
Then there will be offers for the TRW replacement ones- their part numbers start with JTC and four digits then.
These wishbones are absolutely equal to OEM, as TRW is a OEM manufacturer.

I google trw 3110 228 and the first google result is this thread??

If they are legit, wow! Less than half the price places like turner want

Any confirmation?

the TRW code is more like TRW####, the BMW part number is 3110 228###

the concern is Bushing quality because if you google TRW you get mixed reviews for their GM car part replacements

So they're not actually the bmw manufacturer?

They just make oe replacemets for the m3?

Any word on the quality of the arms themselves? Since even if i need new bushings i'll save at least 25%

Ed: quick google of pretty much everyone saying trw is generally awesome and quality, so if the arms truly are the same as m3, i know where ima put my money

Still waiting for the Powerflex inserts, that had arrived to Moscow Customs and still passing the formalities since August 14- hope to receive soon.

The TRW lower control arms should have arrived already, as were on stock in Moscow, but the light level regulator arm is ordered from Germany, thus is expected to arrive within a week or two.
The Girl's 118i inserts and M3 anti-roll bar bushings are in the same order.

Will report as soon as I see the TRWs- curious on the bushings quality but decided for that $200 risk to clear up if should continue with the upper arms of their make.

[Dmitry83]

Guys,

The TRW part numbers for the M3 straight control arms are the following (with the originals numbers for reference):
JTC1426 (OEM 3110 2 228 3 577)
JTC1427 (OEM 3110 2 228 3 578)

Mine had arrived- will see it alive tomorrow or on Saturday and will report on the bushings quality.

[andrey_gta]

awesome!

[Dmitry83]

Had picked up the TRW control arms- seems really absolutely equal to OEM in terms of bushings quality and looks.

The part of the arm, where the ///M logo should be located is machined off after the mould, so it looks a 100% original at the end!

I bought the same (TRW with the ///M removed) and I know form someone (working for TRW) that they are the OEM of these parts. They originally made it for BMW but they can directly sell it (without passing by BMW) but in this case the ///M and all the references to BMW must be removed.


I don't care that the ///M is there or not but you can have all this stuff for much less money if you do that. You can see here the parts from TRW for BMW M3 (and the prices): Oscaro.com


For such a price, I took the entire kit but these for the toe are +/-2 inches too short...:

[andrey_gta]

Excellent news.

^^Nice work guys!

To be honest Andrey, I want to do "a nearly full conversion". As you can see on the pics hereafter, I bought and installed (in fact the car is still without wheels and I'm finishing) the blue parts. The red part is bought but unfortunately cannot be installed. The bushing are the last mods I'm busy with and the rear sway bar is already installed (the front was done months ago). Last Christmas holidays, I also opened my diff to change the mechanism by a Quaife.

On the same time I'm busy with a change of my M-shocks by Bilstein B6 Adjustable 10 and mounted camber plates. The shocks are unfortunately not compatible with the part number 4 of the first pics (camber arm rear) which is in aluminium but need adapted shocks (M3 type).

So I think that it would be enough for the moment


What I really want is a good chassis, tuned like I want with no understeer and go where I want en when I decide. I think that theses mods go in this direction that's why I did it.













About the price, it's difficult to compare because I think it's different in Europe. You can see (hereafter) a link to a local installer which do the front kit for 625€ tax incl. (if I refer to today change rate: 815$) so 150€(204$) per part. These are BMW parts and I can find it on the internet (in Europe) for approximately 120-130€(155-170$) per part (for rear too) but not beter (so their prices are correct).

performance-store.com




I took TRW parts and I had for a total of 700€(910$) for all the 10 parts I have (only 8 usable ) so 70€(91$) for each part for the same quality (only the ///M is gone... but it's less weight finally and I never see it ).



I wrote "in Europe" because I know that the market is different in USA/Canada, so it is clearly not comparable to America and that's why it's difficult to compare (but it's good to know how much does it cost in US, I frequently do my orders directly to USA for my 2005 Buell XB12R ).

[Dmitry83]

Finally the light-level control arm had arrived and the TRW Control Arms are installed!

The inner part of the arm, which is inserted and bolted to a front subframe, needed to me machined for taking off 1/2 mm, which was a minute work.

What had changed mechanically- the camber moved from -0.6 degrees to -1.0-1.1 degrees with -0.9 degrees toe-in.

On the road after having front tires (and my mind!) adapted to a new camber, the car attacks corners incredibly aggressive, squeezing MUCH more 225mm grip from the front tires!

The turn-in is very much improved and became more "transparent" and clear same as the steering input inside of the turn (mean, the addition of the steering angle or something like that).

On the ride quality- can't say I feel any changes- same adequate firm and pleasantly stable with the KW var.1 in the high position.

For the $250 including labor the mod is very much recommended!

[Dmitry83]

Now for the 118i (Girlfriend's E87) "basic upgrade project":

1. A pair of Continental SportContact3 215/45/17 had been knife-cut by vandals, so replaced all four with Continental SportContact5 in the same size (the pressure for the first drive is the same as well).
The new tires are absolutely brilliant: much more comfortable, the dry-grip is significantly higher in all directions, the noise seems absent comparing to the previous model.

2. The rear subframe rear bushings are replaced with M-ones, the front are upgraded with the Powerflex inserts.
The difference is day and night: the car is beautifully planted and stable at the straight, the turn in is WAY better, and quite enough with the existing engine and Eibach-PRO kit with the stock shocks.
The awful noise from the road bumps is totally gone.
To sum up- the car is a pleasure to drive with no irritating issues at all.

3. Though the E92 M3 sway bar is claimed to be the same as a E87 standard one of 26,5mm, the E92 M3 sway bar bushings turned out to take not more than 20mm sway bar. Strange, but seems the E92 M3 sway bar is thinner at the place of bushings, that the straight 28mm E93 M3 one that I've installed to my car.
Seems, Powerflex sway bar bushings is the simplest and the cheapest desision if you do not want to spend some $400 for the E93 M3 sway bar set.

I just bought the e93 m3 anti roll bar, do I need other parts to mount it?

Yes, you need new mounting parts:

31352283037 brackets (2pcs)
31352283967 bottom support bushings (2pcs)
31352283968 top support bushings (2pcs)

Around $100 for all.

thank you!!

and I want to install these bushings:
http://www.ebay.de/itm/220871026745?...84.m1423.l2649

I also bought the m3 rear anti roll bar, do I need the bushings for m3s or for non m3s?

the bushings in the link look like they are for stock sway bar

m3 front are more narrow almost like a Donut. DimitryT has said that m3 bushings only work with m3 26mm bar and not the stock 26mm.

The 28mm FRONT e93 m3 bar uses different 28mm bushings. I have 2 of the lower pieces for 28mm Front bar from a mix up that happened to me ( you will need to buy the top pieces), I can sell them to you. Please PM


I am not sure of the rear bushings

Ah okay now I got it!

So I need 28 bushings for the front (e93 m3 bar) and 26s (e92 m3 bar)for the rear!
I'd love to get an offer from you but I think shipping to germany will kill it!

Could you please give me a link to the powerflex bushings I need!
I cant find any! hopefully they are available over here!

Am I right that they are way easier to install than the stock m3 bushings?
