Trying to correct oversteer, whilst maintain oem feel. I would of done the control arms a long time ago.....if I could.
I missed that important bit of info...

Basically, I'll sacrifice it for the looks and having the square setup I want. If I'm alone in the car my music is on and pretty loud 100% of the time. If I'm not alone it's only with my gf and I already told her to get ready for the noises which doesn't bother her since she dives a '04 civic so still an upgraded ride.

Good luck on the search and let us know what you find.. If I can get an alternative down the road I might if the plates end up being annoying. I'm used to driving 2G Eclipse's so you can't get much more noises and rattles than that!

Any news on this ?

I am activly searching for camber solutions on my M235i Xdrive.

I plan on Dinan springs + bumpstops, camber plates are my last report. Tire wear at the track with stock alignment is awfull...

I have the same model, i use GC camber plates, and Dinan springs.. Very nice combo IMO. I would bite the bullet and do either GC or Vorshlag camber plates while your doing the springs You'll notice an increase in noise the first week or two, and then you'll forget about it.

In case anyone is wondering if RWD bushings fit xDrive front lower control arms - yes, they do.

They appear to be the same size, no additional hardware required. I test fitted camber-adjustable both SuperPro and PowerFlex bushings, they fit, but am currently running PowerFlex p/n PFF5-1902G which is significantly stiffer than the stock. The SuperPro ones appear to be softer than the stock so I didn't actually use them.

The ride is somewhat harsher/stiffer, the steering is noticeably more responsive and there is certainly less understeer.

I was only only able to get -1.15 camber symmetrically (I could get -1.15 one side and -1.45 the other so I made it equal at -1.15).

would also point out that using a stiffer sidewall tire will help a little with the un even wear from the positive camber.

i had run a nt01 on stock suspension with spacers and had even wear across all tires. So don't always jump to needing a full suspension because MPSS street tires get destroyed on the track.

I have the Superpro camber bushings (SPF-4303k) fitted on my F31 xDrive too. I was able to get to about -1.2 on both sides.

Note that although the camber/control arm bushings fit xDrive, when I tried to fit the Superpro tension strut/caster bushing (SPF-4306k) it was too long to fit into the subframe mount on the car. The bushing pressed into the arm fine, but couldn't be mounted to the car. This is weird, because Superpro's European site said it should fit.

With the Superpro bushing I noticed no increase in NVH, and a very slight steering feel increase (not really noticeable unless thinking about it).

I'm trying to get a hold of KMac's +/-2deg camber bushing, and have given them measurements of my caster bushing to see if I can get an adjustable one there too.

Interestingly, KMac said that Raymundo received both the camber and existing KMac caster bushing for his xDrive car, and didn't report any fit problems with either.

Thanks for the input. I am glad I went with the Powerflex bushings then. I actually like that they are so stiff and the feel that communicates. I like the handling and how the front end is more grippy, that you can pivot the car around the front axle by the throttle, etc.

OK, now I am not even trying those caster-adjustable SuperPro ones though I, too, have them.

Also, I wonder what's wrong with SuperPro. Polyurethane is supposed to be stiffer than the stock rubber and they don't look that. Your input only confirms my initial impression.

I want to report that I baught and installed Kmac Camber bushing kit on my m235i Xdrive and we managed to get -2 degrés of camber ! Here are my final specs:

Front
-1.98 camber
0.12 degrés total or 1/16 of toe per side

Rear
-1.8 camber
0.12 degrés total or 1/16 of toe per side

This totally transformed the way the car handles ! And no ill effects or sounds or anything. Your results on camber may vary, I had one side at the end of the adjsutment and the other side with .25-.35 left in it..

Now I can't wait to go trough my 235/45-17 RE71r to install new 245/40-17's

Awesome!

I'm still trying to get my hands on a thrust arm bushing to measure so they can make an xDrive caster bushing. My dealer didn't have any in stock that I could measure the other day.

Is there any noticeable difference in caster? You pretty much got the same amount of camber from the bushing as the RWD people who replaced their LCA with M3 LCA and their caster was pushed way forward without a thrust arm replacement.

I don't have the paper with me but it was around 7

You must be putting some extra stress on the front drive shafts by pushing bottom of hub carrier further outboard

In theory, yes. Still, damage or premature wear of any part as a result of it has yet to be reported. It's a rather common modification for various cars but I don't think I've ever heard of anything failing due to that. Maybe the difference is too small to cause anything to fail. I'd call this a safe one, at least with the usual adjustment range of about 1 degree.

PS: bmw makes oem camber correction steering knuckles, min 30 min, plus 30 min, basically the same idea, and those are apparently well within the safety margin.

M235i x drive already have the -30min knuckles installed

-30min to -2 deg is still a sizeable change in geo

In real life, RWD or AWD, knuckles + adjustable bushings, you are not getting anywhere close to -2 deg. You'd still max out at about -1.2 deg one side and more on the other side but would set it at -1.2 equal (powerflex, superpro offerings).

That may not sound like much but when you think and compare in terms of -0.5 vs -1.2 it is a noticeable difference. They do change the way the car handles. They are great, cheap and easy to install and adjust. I do think they are still within a safety margin, and I've never heard of anything failing due to that kind of modification. I used 3 powerflex and 1 superpro camber-adjustable bushings, never had a problem.

For a track car camber plates are usually the way to go, obviously, but for a daily driver... having used camber plates on my other cars, I do think they are an overkill and unnecessary (for DD) when you can only do the bushings.
Sorry but I got -2 on each side from the Kmac bushings..

I get it, mistakes happen. That's life. It's how people react to those mistakes, and I feel both companies have been very helpful.
After everything was sorted out, what exactly did you end up with from KMAC and how are your results?

The M control arm achieves the same thing only by making the aluminum part of the arm longer. For a given camber they will both have the same wheel geometry.
If the bushing pushes the ball joint end further out, does that also move the entire wheel out further? I know that's the case with the longer M arms, where the entire strut will move outward and you lose fender clearance.. But with these bushings do they negatively affect distance to the fender in the same way?



With longer arms it's easy to see how the entire wheel would move outward. But if the bushing goes in the ball joint, doesn't that only tilt the bottom of wheel out? And the top of the wheel closer to the strut.
