This is something I’d also like to know

KW clubsports don't have amazing clearance and camber adjustment runs out at -3

By any chance do you have the bolts torque specs and how long it take it?

So I just installed these new hubs to get more camber on my 21 m2c. Had my local Bmw indie shop do the work. In front, the base alignment camber was -1.0 on the left and -1.5 on the right. They played with it on the alignment rack for 2 hours after the install and could only get -1.3 on the left now and -1.8 on the right. So both sides improved -.3 but we thought we would get -.5. We can’t figure out why the left won’t adjust as much as the right. Toe on both sides is .01 in so basically 0. Thoughts? Car is completely stock with stock wheels other than the new hubs. Tires are 255/35/19 on front and 275/35/19 on back. AO52s. Thanks in advance.

.5 degrees difference between the two sides sounds like a lot - how did you have the car ballasted?

Update: Also, what were the rear settings measured at? Have you got a before and after print out you could take a picture of and post?

I think you could work on the basis that it is adjusted around the centre line, so you could assume its less that 2.5mm n a 19 and nearer 2mm on your 18's to the rim edge

I am super pleased with my hubs and hated the NVH with Milway 'street' camber plates

The M2 CS Racing appears to use the standard hubs with 10.5" x 18" rims. But does also have camber plates and the springs are cylindrical.

Here are the alignment before and after specs.

I also have the old knuckles/hubs for sale here if anyone is interested:

So no one has seen this problem where the left side is different than the right? Surprising actuallly. I guess I'll take it to the dealer (tried a BMW inde shop who installed the nuckes but he couldn't figure it out). Any thoughts woudl be appreciated.

I'm sure you've already thought of it, but do you know the car's full history? Sometimes cars have damage before delivery and are repaired at the receiving port.

No clue on this information. I bought the car used with 5k miles on it. So who knows what it could be. All I can do is take it to a dealer at this point I guess.

Any news on this? In my case it's either going this route or just doing camber plates and calling it a day.

Like they say “resurrecting an old thread”.

I read this posts last year and went ahead with the mod on an M2C (CS knuckles, hubs, M performance HAS) and somehow missed this question. I am experiencing rubbing of the front tire on the spring, using 19” Apex Wheels with 255/35/19 Tires. I put a 5 mm spacer which is the most that the replaced wheel stud kit will take. Visually there is (minimal) clearance but still there’s ocassional rubbing.

Any idea what else to do? Wider spacer with longer studs? I love the wheels, I love the suspension. I dont have camber plates the camber was achieved with lowering and the CS knuckles and I am pleased except of course for this issue.

Thank in advance!

Assume you are ET 28 ? I run 9.5 ET 22 with -ve camber hubs, you might be better off with say 7.5mm Turner motorsport spacer, they are hub centric

If you can see where the tyre is rubbing a little file or Dremel just to take 1-2mm off that section might be a consideration (Not tube obviously but height plate)

Yes ET 28. I bought the wheels initially for the stock suspension so I didn’t even consider getting ET 22 or use a 5mm spacer beforehand. Well now I know…🙄

The thing is even with the 5mm I get rubbing. And dont worry about taking the Dremel to the height adjuster… the tire has been wearing it down on its own. 😆 Probably the reason it is now only “ocassional”. It has not affected its function (yet). The spring also has its paint worn at the contact point. It still is a safety concern for me.

I wrote to Bimmerworld and the very knowledgeable Randolph King wrote back a very detailed description on spacers, stud length and safety. What I will do is determine if 7.5 is still good for the studs I have and go from there. Don’t want to push it outwards too much either.

Thanks!

what's your front camber now?

Ohh boy… glad you asked I was under the impression it was more negative but this is what I found after the CS knuckles and the lowered suspension and alignement.

Surprisingly I have not destroyed the front tires (at the track) so I am likely driving around the problem... they do of course wear the outer shoulders more.

Wait, so you've not gained any negative camber?

[azacad]

To be clear I dont have measurements BEFORE the CS knuckles and HAS. From what I read baseline stock is between 1.2 to max 1.5? So probably I did gain front camber. My “baseline” with knuckles installed and HAS lowered is below. Further alignment yields no front neg camber gain which makes sense if there is no real further adjustability. Not so for the rear I did gain there. I was hoping for closer to -2.5 front without camber plates but this is in line with what others with similar parts have.

This mod sounds cool and won't drastically affect tyre wear for the commuting?

With regard to recommendations to cut threads for new or old bearings being used what does this mean? Tapping the holes.?

I know expensive but don't need -3 camber and it's OE.

Would work with my B16s? (lowered but still -1.26 and -1.3 L/R camber)

Cheers

Hi

Yes - can confirm even tyre wear for DD.

When swapping over wheel bearing housing these are held in with single use bolts so just need fresh bolts to fit existing front hub bearings into camber correction hub carriers.

Should be ok with B16 - I’ve had these installed for a long time with MP c/overs and zero issues.

Thanks BP, I came across this all again as wanting to see why the M2CS is so praised in its handling, thought surely our cars can be modified in some way? One internet search later annnnd..
Hear you re new bolts being needed, sounds good.

Did you go 255/275 in the end as that is what I am running, no rubbing up front?

Presumably I would still otherwise align the car to Litchfield spec albeit with the half degree additional camber?

255 upfront on track and winter wheels - no issues with either.

Litchfield alignment with extra front camber will no doubt work well
