E92/93 Owners With Aftermarket Wheels - Take Note

[kenntona]

This issue first surfaced when I changed my wheels. Post-alignment, Ah Wee (BVO) told me about the lack of turns on my rear lug nuts after changing to aftermarket wheels. The OEM rear lugs screwed only 5 turns into the lug holes. Ah Wee explained the concept of precession and the risk of fretting to me. I had since changed to longer lugs for safety reason.

Now I am seeing this happening:

The next time you change your tyres or go to a workshop, ask them if the OEM lugs are too short for your aftermarket wheels...

After mkt wheel makers should also advise if the OEM lugs are reusable.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

yes this happens to me before... the tire shop guy told me not enuff turns... in the end i bought a new set of longer lugs...

BTW my friend bought some aftermarket wheels... sometimes they provide with the longer lugs

Hi Ken, for E90, do I need to change to longer lugs? where to? thanks !

Steven, I have not heard anything on e90 yet.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

I think this serves as a warning to all cars, regardless of make or model with aftermarket rims. Be safe rather than be dead.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

i tot the problem was due to spacer? if the wheel mounted directly with stock nut should be enough, right?

a longer nut might not be good either, if the strength of the nut material doesn't hold up the wheel it will still cause problem.

I'm quite amazed at how he managed to remove the snapped bolts with just a screwdriver...

Is there any embossed reading on any rim where we can check how thick is the stud mounting hole? AFAIK only stud diameter is listed on rims.

The problem should be the length of e92/3 OEM lugs, insufficient length for the thicker aftermarket wheels' mounting hub. Even for wheels without the need for spacers, example DPE, the OEM lugs penetrated less compared to stock wheels. I suspect it is a combination of (1) lug length (2) high torque figures of some of these e92/3 335s.

The assumption is that you dun go for cheaper lugs. Tyres, wheels and brakes are the most important aspects of your car when your need them most to save lives, so no one should save money on them.

Very well said! Sadly not everyone follows this advice.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

Not sure how that could have happened. My ACS type IVs in 21s came with longer lug nuts, in fact, most of the respectable aftermarket wheels I've come across come with longer lug nuts.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

Ken, can you check with DPE whether we should change to longer wheel bolts? Do they have it?

yes quality of all this components are top priority.
from the pictures i can see those broken pcs are left inside the hub screw hole,so i think is not due to too short the lenght of bolts, if is too short the bolts should have flown off the wheel. i think it could due to over torqued or tighen or poor quality bolts?
OEM bolts is reusable for some after market wheel, just make sure the sitting is the correct type,and sufficient lenght like 6 turns is minimum correct me if i am wrong.
One important thing to take note is make sure the wheels are hub centric(centre hole of the rim must sit properly on your hub centre, most after market Japanese wheels need centre ring . not sure about the Pic enkei rpf1 wheels require centre ring ? iif not running on not hub centric wheels are very dangerous for wheels that are bolts on(unlike japs car are Nuts).
Sad to see such thing to happened like that,
most shop using power tools without proper setting can over torqued the bolts which after numbers of over tightening can cause bolts failure

How about these bolts? hahaha !

No lah..its definitely due to too short bolts. Too little turns into the hub...the part of the bolt that is not in the hub becomes a lever and the vibrations of the wheel is the force. Think of the hub as a fulcrum.

If the bolts were overtorqued, the dude wouldn't be able to remove the broken bolts in the hub with just a screwdriver.

Re: E92/93 Owners With Aftermarket Wheels - Take Note

no doubt these are Superb quality botls but it still need proper/correct application and proper installation proceduressss.(power is nothing without control)
So guys be aware of swopping wheels between car by yourself especially the transaction between owners in the internet ,the seller or buyer always thinks every is the same so long it fits to your car.
Best get the relaible shop to do the swopping
YOu can take my words for it , things are not as simple as what we thinks.
Different products/shops/even persons carry different Quality
SO dont always think that every where /shop/person you go is the SAME.
Only Issue we always think is $$$$$ different that is why we always check around for $$$$ but not quality.

why he can easily remove the broken bolts? becos there isn't any more tension just like you hand screw the bolt in and out without any tightening with no wheel on.:screwedu:
i am not totally agreed with you,because you can still see clearly the broken bolt can be seen is inside the screw hole?
If the bolts are too short the bolts wont be there any more it will be flown off.
Anyway this is a lesson that owner learned and not sure the workshop learned it too:thinking:
Honestly speaking this issue is actually not car owners duty to check,
IS the professionalism and business ethic of Workshop/wheel shop or what ever service provider.
