    Hi Cutters,

    I am looking at a set of Eibach (aftermarket) rear lower control arms for my 3.0 M3 saloon.

    as in:

    https://www.turnermotorsport.com/p-373284-pro-alignment-kit-billet-aluminum/

    or any other recommendations??

    However, a question I have is, are these recommended for everyday use? My car sees 1 or 2 track days a year - usually pretty light club sprint sessions and, err, that's it - the rest of the time its my daily. Are these ok for everyday use?

    Surely they must be safer/better than the oem pressed steel jobbies - which I think are so cheap and nasty..

    What says ye???

    Winno.

    I'm no expert but I'm sure they'll be fine for everyday - I hope so anyway as I'm just having some adjustable lower control arms fitted before having a full wheel alignment done.

    I went for Powerflex arms which I got from driftworks for about £140 I think. I went for them partly for price but also that they should be an upgrade to standard but without out going too harsh with spherical joints. Like I said I can't recommend them yet but they certainly felt more substantial than the standard arm

    I would imagine they’re all fine, be hard to make anything as thin and flimsy as the oe ones.

    Id probably go for something with a poly bush although one with a spherical bearing would be fine if they’re rubber booted, doubt you’d get any increase in nvh either considering the outer ends already have ball type joints.

    One thought though is the oe arms are probably designed to be a sacrificial weak link to save the rest of the suspension / body should you accidentally whack a curb sideways.

    If you wanted to stay oe spec you used to be able to buy new arms with the bushes in for barely any more than the bushes on their own. The part is also common to all e36s and e46s including both versions of m3s.

    I’d most likely go for eibach or powerflex on my own car rather than a random eBay brand.

    I've been using those Eibach ones for a few years they are excellent and still in perfect condition years on... I had some cheaper ones for a few years before that which also worked perfectly well, you certainly won't tell the difference from inside the car! but they were pretty chipped and seized eventually so I replaced. You could argue that you can have a new pair of cheapos every year for a while for the price of the Eibachs!...

    I have a pair of ebay ones fitted to an e46 b3 needed them because it’s lowered. However once set they never need touched, if they do it’s probably because something else has deteriorated. The covering on them is **** including threads and locking nuts rust. From a looks point of view I should have painted the shaft slid some heat shrink on then had the car setup and then put the heat shrink over the threads to preserve.

    I’ve had a set of Eibach arms on for around 40k Miles and they’ve been fine so far and still adjust perfectly. Just make sure you unscrew them fully and grease all the threads when they’re new and you’ll never have an issue.

    I bought a set years ago off Ebay for my 328i.

    Never fitted them as they were extremely heavy and I reckoned they would increase unsprung weight too much.

    Ha, ha.. I can't believe the weight of the suspension on the BMW compared to that on the Lotus Elise S1 (The M3's garage buddy). I reckon the Elises TOTAL suspension package (minus Nitron adj coilover suspension) weighs about as much as 1 cast rear trailing arm from the M3.

    Fark me that thing weighs a fricken tonne. I wouldn't be worried too much about the weight in the control arms when there is so much in the rest of the suspension.

    I reckon you will dig up dinosaur bones and e36 M3 rear trailing arms in about a Millenia...

    Adjustable aluminium camber arms should weigh less than the crappy OE pressed steel ones I would think. And if you're not getting alu adjustable arms then you're not getting the right ones.
