I'll absolutely do some further research and will look at obtaining these shims. My concern there is having upgrading my brakes and wheels I can imagine BMW won't offer to warranty anything. Is there a part number for the shims?

In addition I was unable to open the files you sent, are you able to PM these to me?

Thanks
sorry, I don't know why the TSB links are dead. This one is still active:

There are a few part numbers for the friction disc, one of the 5x112 discs is 34 10 6 884 839. The shims that BMW sells don't always align with the rotor alignment hub tabs that some cars have that index into the rotors, but if you use the disc between the wheel and rotor surface, that won't be an issue.

Also I'd recommend reaching out to our support email support@apexwheels.com. My colleague Dan is tracking these tick issues and solutions for them.

That's really helpful Tom, thanks ever so much for sharing this! I honestly thought I was the only one with this problem!

I'll email Dan, thanks again!

Hi Tom,

I haven't emailed Dan on this yet, as wanted to see if I had cured the problem. A bit of an update, shims purchased from BMW, and fitted per the TSB, I fitted them between the hub and disk after cleaning all surfaces. I also applied aluminum grease between the disk and wheel to prevent any corrosion build up. This has stopped the clicking from the front...

I've driven the car for three days and have now noticed the same noise from the rear.... 🤦🏻*♂️

I wonder whether I can copy the process for the rear?

Thanks in advance!

Nathan

I'm going to place an order for VS-5RS and I think I have the specs finalized, the basic 19x9 ET25 and 19x10 ET38. I think I'll be going with a 275/35/19 on the rear, but I'm not confirmed on the front.

I want to put 255/35/19 but I also have ST coilovers. Currently on supra wheels with a front 32 offset and a 15 mm spacer. It's rubbing heavily, all the tread on the inside tire is gone.

Would putting on the same 255/35/19 tires result in rubbing? Even with a 5mm spacer?

The supra wheel is 32 offset minus the 15 spacer comes out to 17. The VS-5RS 25 offset minus a 5mm spacer would put it at a 20mm offset. That's only about a 3mm difference but do you guys think this is enough to clear? Should I get a thinner spacer 3 or 4mm?

I'd be willing to change it to a 245/35/19 because the tire sidewall is only a few mm off from a 255/35 so my ride height in the front would be the same. What combo of spacers and tire size do you think would make it fit?

I spoke with a Apex expert and our conversation was toward a 235/40/19 but after I've thought about it for a while, I would rather have that extra track for better handling and less understeer.

Even if you're fully able to resolve the issues without Dan's assistance, please do reach out via email as the tracking of how often this is occurring and the other specifics around your brake options is something I'd like to have on file. I'm glad to hear it was effective up front. The same solution can be tried in the rear as well although honestly you might just want to try putting the shim between the wheel and rotor mounting face instead of the hub and disc to see if the noise is eliminated so you don't have to pull apart the brakes.

If I understand correctly, you're currently running a 19x9 ET17 effective front fitment via a supra wheel with 15mm spacer. That setup with a 255/35-19 tire is still rubbing your suspension on the tire sidewall.

If you ran our 19x9 ET25 with a 5mm spacer, the effective offset would be ET20, 3mm closer to the strut assembly than what you have currently. If you were to use the same front tire on our wheel, it would surely rub. A 245/35-19 on the same setup (apex wheel + 5mm spacer) might clear, but it might not. You're gaining additional room thanks to the narrower tire, but losing clearance to the strut because of the effective offset increase.

This KW setup is really reducing your front inner clearance. Far more than other cars I've seen with similar suspension. I don't know if my colleague mentioned it as an option, but raising the car's ride height up front or even switching to a different spring up front with reduced stack height could move the lower spring collar up and out of the way of the wheel and tire and reduce the odds of rubbing.

You don't want to stack spacers, and running an 8mm spacer to get the Apex wheel out to ET17 effective is also not advised as it would eliminate the hub ring engagement. 12mm is the closest spacer we offer as a next step, but I would expect that to rub on the fender side unless you dialed in negative camber via camber plates.

There isn't a magic bullet here in terms of wheel fitment. Our 19x9 ET25 wheel + a 5mm with 245/35-19 could potentially work if the tire decreases the section and tread width by a sufficient amount to compensate for the effective offset increase. I would also recommend potentially adjusting the front ride height or changing springs to improve clearance.

Hi Tom,

I called my local BMW dealership this morning and ordered another pair of shims. I'm currently driving the car without centre caps as initially thought this was the cause of the noise, so want to try and address the problem step by step.

I'll try the shims between the wheel and disk face and see whether that works.

Either way, i'll absolutely document it with Dan so he knows the problem and (potential) solutions.

Thanks again for your help!

I don't want to change the springs as they were the springs designed by KW to match the dampner. The ride height is set relatively high already. What wheel specs would you recommend to get around this? Or could I just fit a spacer between a 5mm and 12mm that is hubcentric with the stock ET25 offset? To me, it doesn't even look like it's rubbing on the spring perch or spring because it would have some markings on it. Don't mind the rotors, yes I know I should replace them but that's another conversation. I do have some custom mudflaps that it could be wearing against when on full lock and elevation change so maybe that has a part in it.

Also for the rear would a 275 fit well on a 9.5 so I can go for a ET25?

If you're looking at running no spacers, a 19x9 ET25 with a 235/40-19 should clear. However, just note that every tire model can be different sizing than one another.

As for the rear, usually we recommend a 19x10 ET38 as the fitment would be equally flush front and rear with a direct fit. If you ran a 19x9.5 ET25, you would need somewhere around -2 degrees of camber in the rear with a 265/35. A 275 would require more camber and/or a rear fender rolling.
