Another BBS RS question

[alexbaby88]

When refurbishing a set of RS wheels, the center is painted and the lip polished. Any clear coat or lacquer on either?

If dismantling I understand there is some sort of o-ring between the lip and barrel. Where can I find this o-ring?

I have been advised not to dismantle unless absolutely necc.

[Madhatter]

depends. clear coat for a machined surface, a highly polished surface usually wont take clear very well so quite often it can simply be polished metal covered by wax to help protect it against corrosion.

some wheel manufacturers might use gaskets, but most these days (including the majority of people who repair/restore them) will use a silicone based sealant.

True, balance and warping issues can occur. There is no real reason to pull them appart unless they are damaged. If restoring them and painting centres, clean the wheel then spray the wheel the colour of choice, dont mind about overspray on the lips. Then hit it with your choice of clear and let the whole lot cure.

Then you can go back, mask up the centre section and spin up the wheels, strip the area of paint and polish the surface with sandpaper and grit polish or compound block as needed.

The older style BBS racing wheels use a spacer ring with "O" rings. The center piece bolts to the outside of the halfs. Not used or should say, "should not be use on street"

BBS in Georgia will refinish them but for big dollars.

Can the nut/bolts be reused if taken apart?

I have a BBS RS002 dated 03.84 When i took it apart there was no gaskets or o-rings. Only thing that i saw was alot of silicone. And there was a tire on it that did hold air.

Can the nut/bolts be reused if taken apart?

Yes and no. They have stretch tolerances they are essentially aircraft grade hardware. They can be checked for stretched.

It's quite a easy job to take them apart, putting them together is even easier.
I see no reason not to take them apart if painting them. It's lot easier to work with the wheels if they are in 3 pieces.

There's silicone-sealant between the 3 parts. Easiest way to put them together is to bolt them (remember loctite on the bolts) and then to put sealant to "big seam". Let it dry 24h and the another layer. 2-3 layers do fine. You'll know what i mean when you have the wheels on your hands.

I recommend using new bolts and nuts, at least nuts. What's the point in repainting the wheels and then using old, dirty bolts and nuts (you can't clean them very well, lot of little corners).

I built these wheels for my E30 cabrio last winter (8,5 + 10x17"):

What are the bolts supposed to be torqued to?

The "BBS RS & RM refurbishing" - thingie is worth reading :)

ZOMG XD

Are you running adapters? I noticed in your other pictures you have 4 lug suspension, but there is no RS in 17" that is 4x100.

That is a great site with some hot-ass thumbnails

Thanks, they are pictures of my project (should be ready next summer) :)

I've ET 14 both front and rear. Rims are 17", originally 5x120 but now 4x100 ;-)

I bump to ask how you changed from 5x120 to 4x100. Adapters? What'd ya do?

WOW. those 17" RS's look amazing. cant wait to see some finished pics of yer cabby.
