Astra with Audi rims...

[sooty]

does the collar move around for a neat fit? (like a washer) or is it fixed to the bolt like normal ones?

I assume the collar would have to move around the bolt, otherwise there's no way that the thread could screw in as the collar would continually hit the wheel..

Here is a TS with those wheels ! the chick who bought my car put them on. personally I dont like them...but then its not my car anymore.

Don't suit the car I'm afraid!

Missed this post - looks like I'll have to put some info up on them...

Will have to be this weekend when I've get some time to take pics of mine and give you guys a a bit of a description on them

thanks mate I do want to know more

I cant visualise it and its making me all antsy.

Woudlnt the bolts make the wheels off center to the hub? ie: if all of the bolts were touching the bottom of the collar????

*punches head*

I don't doubt that they work (else no one would use them). I just cant wrap my head around it.

DOesnt help that its 12:30 am haha

Correct...

It moves around about the bolt (hence the name 'wobble') and sits neatly in the chamfered lug recess on the rim, with the bolt being off centre to the washer but neatly seated and perfectly aligned and screwed into the hub threaded hole...

As mentioned if you can all wait till the weekend, I'll take pics of my Momos with these lugs and put them up...

For anyone interested, this topic was raised about 2 or 2 and half years ago by BR (Blueraven) and I explained it all with pics of my rims back then, maybe a search will bring it up

I would have thought that it'd be centered by the lip of the hub that sticks out in the middle around the driveshaft spline as shown here

Had a quick search on here for "wobbly" found some old threads, one had a decent description in it.

the collar is seprate to the bolt so moves independantly to the bolt, so to make the wheel fit a slightly different PCD you use the wobbly bolt to make a tight lock onto the hub. As the bolt goes in the wheel the collor locates in the hole before the bolt, this means as all the bolts are tightened the bolt locks into the collar not the actual wheel and therefore allows the bolt to fit a slightly different PCD and still locks tight onto the hub!

That's a very good brief description above ^^^^

Another point to note is that wobble bolts are really only used on capped rims, ie: rims with a centre cover cap.

The reason for this is because the 'collar' is too large to be used on exposed hole rims and would require the lug hole to be huge, but in rims with a centre covering cap there's alot more room to play with in this regard and the final look dosn't matter as it's all covered up...again I'll post pics of my Momos so you can all see what this looks like

And as with all aftermarket rims, because they're made to suit all types of cars the centre hub hole is oversized and they employ a 'CBL' or more commonly known as hub locators to centre the wheel - this is not something that's done by the lugs on any wheel, they're usually plastic rings but some of the high end rim manufacturers (Momo etc.) make them in aluminium

thanks for the info guys.

Im gonna check out what the legalities of using these bolts are
