Some useful information on this website about the use of washers on wheel bolts.

I believe that the loose washer on the oem bolts makes for a perfect centering on the hub each time. The use of a bolt without a loose washer may also yield correct centering and thus no vibration. However, it is more left to chance and the risk of incorrect centering remains.

I agree that the hub is 5x112 standard Audi spec.
 
Re the wheels I' not sure. The need for special bolts on OEM rotors casts doubt on this for the wheels themselves.

More than likely Audi use floating washers on there wheel fixing bolts so they can get the correct contact on the wheel fixing face when there tightened up properly mate.🤔

I've always found the oem wheels give me the most grief to get off due to there interference fit on the hub spigot🙈unlike aftermarket one's.

Also i always nip my wheel bolts up before final tightening with the wheels off the ground so they centralise on the hub spigot properly, then finally torquing up the bolts back on the ground mate.

I can agree that the wheels are 5x112, but it is evident from this thread and third party specialists that OEM style loose collar bolts are the proper way to go to avoid problems. So Tony's advice is not correct IMO.

If the wheels are a interference fit onto the axel spigot it wouldn't make any difference what bolts you use as the spigot takes the load not the bolts which only hold the wheel to the hub face.

I know of an instant were Cosworth Sierra wheels were fitted on a MK2 Escort which have the same stud pattten but the Sierra uses a slightly larger spigot, some of the wheel studs snapped off on the motorway.😫

Btw the 8Ps use the non floating washer wheel bolts with no problems from the factory. 🤔

Wow loads of comments on this today🤷‍♀️
The only thing I can say on the subject is that the problem was solved with the floating washer bolts, also H&R Germany replied in an email saying the RS3 should have the floating washer type bolt.

Going back to 8P I had horrendous wheel vibration problems with my RS3 8P.
Audi wanted the wheels force road balanced more than once to try and solve this issue, looking back the wheel bolts were a fixed radius bolt.
Makes me wonder if the reason Audi opted for the floating washer bolt on the 8V was because they learnt from the complaints from the previous model?

I rang my original Supplier this afternoon and 2 other H&R official resellers and they all sell these spacer kits day in day out with single piece bolts, when I asked if any RS3 owners had an issue with the bolts supplied they all said no.

No Audi A3 before the 8v used the floating washer bolts & the radius seating of said bolt has been used since the MK1 Golf.........thats some water under the bridge.

Only issue I ever had on the 8P was an issue getting the front Alloys balanced correctly, then one day after having the wheels off I noticed the vibration had gone....

I marked their location on the hubs and then undid the bolts and moved them 1 bolt hole forwards then torqued up the bolts and tested, sure enough the vibration started again.
Reversed what I’d done and the vibration went away.

How weirded   Good bit of lateral thinking on your part mate.

[0120raptor]

Just to put the cat among the pigeons. Has anyone considered disc imbalance.If the wheels are slightly out of balance
and the disc also out when the wheel is torqued up depending on the rotational position it could be really good
balance or really bad balance.I say this because when I had my new discs I checked them for balance. 3 were good 1 was
miles out.

Now there’s a thought.

Especially after you showed me that disc of yours on the balancer that day I called by.

How the f### could any off us find a work about for that one if thats the case mate.? 🤔

Easy. Send me your discs for balance free of charge.

Some great info on here guys.
I have personally had a car where a front wheel came off after the bolts snapped. This was due to a garage leaving out the spigot and I am lucky to be alive still.

My personal experience with the RS3 was finding it much more sensitive to wheel imbalance than other cars I’ve owned. This was made worse when I bought my OZs and added spacers. Eventually everything was sorted out by Revolution Wheels who had some one of hubcentric spacers machined. The fit was perfect and after putting everything together with the allingment bolts it was better than when I first picked up the car.

By their action, I would concur that Revolution Wheels are indeed professional.

 

There are two types of centricity methods for road wheels - bolt centric  and hub centric. Former is used in slow rotational wheels - large trucks and the like and the latter in high speed applications.

 

With hub centric it is all down to the accuracy of the hub. OEM wheels will be machined exactly to the hub, so that if a bolt hole is a few thou out, the vast force of the wheel bolt will not pull the wheel off centre. Aftermarket wheels generally have polyurethane inserts that I am sure can be compressed off centre if there is a rogue wheel bolt misalignment. I suspect this happened in your case, so full marks to Revolution!

 

In Quattro's case he had alloy machined faces on hub and wheel, so should not have happened, even if the bolt holes were out - unless of course H&R's machining of the hub was a little bit loose in which case a fixed head bolt could have pulled the wheel a few thou off centre whereas the loose collar of a floating washer bolt would not...

Anytime Dell. If you want to bring the car up and wizz the discs off I`ll do it while you wait.
