Finally, a good non-camber plate camber solution for xDrive (and RWD too)!

I don't believe it should. I didn't notice any difference when putting my wider track wheels on.

good morning, what are the advantages and disadvantages of mounting the lower arms of the F80?

Pros I Guess are better feel and front end grip
Cons are NVH mainly.

I would be interested to know if F80 arms can be refitted the bushings from the standard arms to retain some NVH characteristics, though possibly losing some directness.

Whats de meaning of NVH?

thanks!

my bmw 440 comes standard with 0.9 degrees of camber. I read here that they have 0.5. I do not know if in the European market it is different (I am from Spain).

I do not want noises or vibrations, so you only recommend me adjustable powerflex silentblocks?

Can you put some arm of the F80, would it have gain in camber?

Regards, and thank you very much

you only recommend me

To farkle several months/miles later, are you still pleased with these bushings? And if negative camber has such positive effects on driving performance what is the downside? Why would bmw be so opposed to it when designing the car?

I have no complaints about the KMAC bushings (aside from one-time issues you might encounter on installation). I still highly recommend them.

Typically mfgs don't offer solutions like that due to NVH concerns, tire wear, and cost. You have to remember they're designing for the lowest common denominator (otherwise the F3x wouldn't have been so soul-less and comfort oriented). If you look at more niche vehicles (such as M-cars and Z4/Supra) you'll see higher negative camber and stiffer bushings as OE.

Will this fix the outside tire feathering/wear issue?

Thanks again. I felt lazy after asking yesterday so I Googled a bit and read up on camber for myself last night. Seems like a little more wouldn't hurt, so long it's not excessively negative. You guys need to quit finding mods for us! I'm never going to retire at this rate... Or I just need to avoid the dang forum.

If you're talking about getting more wear on the outside and shoulders of the tire vs the inside, then yes, you need more negative camber for that.

It might help with this but feathering is usually a sign of poor dampening or tired shocks not being able to keep up with how the wheel is articulating.

Unlikely with a car with 25k miles

I am looking at these bushings as a way to increase camber. Thankfully some genius at BMW decided that adding a front axle to the 340i was a great way to combat the now tablespoon of snow we get annually thanks to warmer winters. Billions in snow removal infrastructure and snow tires? No, no, let's ruin your front end suspension tuning options by adding an axle. Everyone knows that adding more sh*t to a car makes it WAY more reliable.

My question is way, way more basic. Which 'control arm' do the K-Mac bushing replace? The nomenclature is killing me. There is the wishbone and the tension strut (which itself acts like a wishbone). I wish they would have called it the 'straight' one and the 'wavy' one. So the K-Mac bushings replace the bushing in the 'wavy' control arm or the 'straight' arm?

Please let it be the one where I have to partially remove the axle so I can add another hour to a straight forward repair.

The KMAC "camber" bushing described in this thread is for the "wishbone/LCA" or "straight" arm that doesn't require the collar bolt to be undone and is a pretty quick swap. It's no different than swapping the part on the RWD model.

KMAC also makes a tension strut "wavy arm" monoball that allows you to adjust caster.

lol I was just going to say that! I'm going to go with the KMAC when the snow stops here and it's warm. Thanks for the info!!!

I will never recommend Kevin's work again.

He is inconsistent at best, although we are only lucky that he is down the street and so he can actually remedy our issues in person.

Latest kerfuffle is a camber plate that was manufactured out of spec. Caused catastrophic failure of a B14 strut - Kevin is paying to have the struts rebuilt and has refunded the camber plate part.

This was after the same camber top made for another friend had a hairline crack on arrival which Kevin also paid to remake and reinstall.

FaRKle! - ok ok ok you got me reading! A couple of things:

1. Tilt - with the camber plate, the wheel tilts inside of the fender well. With the KMAC bushing, does yours do the same?

2. Caster - Camber plates keep the wheel caster static. But will the KMAC bushings move the wheel forward like the M3/M4 control arms?

Eying the KMACs as an option.

1) Lengthening the LCA pushes the bottom of the knuckle/wheel outwards instead of bringing the top of the wheel in.

2) Due to the geometry of the arms, increasing the LCA length also increases caster. It's not a large enough increase that would require you to do something about it though (I liked the additional steering weight from it). IIRC it set my caster from about 7deg to 7.7deg.

exE36M3 · 09-21-2020, 12:47 PM

FaRKle! - thanks! What size tire and about how much room do you still have from fender to wheel? The 435i is tricky because my wheel well isn't like the other f30 cars. My best guess, in making the track 2" (?) wider than the F30, they left the fender well the same, thus all these fun tire rub issues.
