Hi all I need some help

I recently acquired a set of these.




I was wandering if anybody could point me in the direction of someone who sells new bolts them? Or someone who has the tool to take the bolts out? The bolts have ten splines, so nothing I've got will fit (Multi spline sockets have 12 & TORX have 6, Ive tried both). Also dose anyone know the dimensions off the bolts? I really don't want to cut them off but its looking more and more likely. One last thing dose anyone know were i can get new badges for the centre caps?

Sorry about all the questions I'm just desperate to get these refurbished & on the car.

Thanks Mike

Hi Mate, having been through all this myself recently I might be able to help.

First thing to say it post a shot of the nuts on the other side of the rim!

My BBS Style5s are two-piece rims and have a normal hex-nut on the back of all 34 bolts per wheel.

Once you have the nuts off you need to very carefully tap out the bolts if they're splined. It takes forever be warned!

The last set I did wouldn't budge. even with hammer blows via a wooden block. I ended up taking them to work and using a hydraulic press to press them out one by one. The most ridiculous bit of this was that it took between 1 and 2 TONS of pressure PER BOLT to move them. The corrosion product (some sort of oxide) has effectively bonded them in SO hard. When the pressure was high enough to crack the corrosion product, they flew out so hard they chipped the epoxy floor of the workshop. It was very precarious and I was flinching with every one - I had 130 or so to do !!! Once they were out I soaked them in viakal for a couple of hours and this digested the corrosion scale which was left on the splines. I then cleaned them up individually with a wire brush on a dremel / drill.

has that put you off yet?!?!?!

I do however have a complete set of Stainless bolts which I bought brand new from Persche and Partners in Germany they weren't cheap @ £160 for the full set including stainless nuts too!

Google ''Titanium Touch'' and send an enquiry asking what bolts you need if you want to buy new ones, you WILL need to liberate at least one of them though, so you can see what type you need.

Sorry to be the bringer of bad news. Buy the right set of wheels and you can have a seriously rewarding turnaround to be proud of, buy the wrong set and you have so many man hours on your hands to sort them out it just isnt worth it!!

Alfter you done all that you need to split the rim from the star, not always easy itself - even with the bolts out!

The use Nitromors to strip the lacquer form the rim and polish them. It looks like you have some pretty deep pitting in the usual area around the holes in the rim; this is a galvanic corrosion effect and is a fact of life unless you can effectively electrically insulate all the studs from the rim - not easy!!

You will need to get the rims machine-cut to remove the pit but don't remove too much material... The other option is to live with the pit and just polish them up as best you can!!

give me a bell through Pro-detailing if you want to know where to get the kit to polish them from...

Cheers - Nick.

Hi Mike,

the problem Nick is describing is limited to BMW Style 5 rims as the bolts have no torx or whatever head and can not be held with a tool.
The issue on your HARTGE rims is most likely that HARTGE is using the same type bolts/nuts as OZ does (maybe the rims are actually produced by OZ?). If so there is no way around getting a special set of tools to remove them. The cost is around £100,- for a set.

These are the screws used originally on the BMW RC Style 5 rims:

OZ did produce some of the hartge ones, not sure about these splities.

Are these 17" or 16?

Thanks for the response guys.

The wheels were made by O.Z . There 16"

This is whats stamped inside.





These are what the nuts look like.





I spoke to someone at birds who said my only option is to send them of to O.Z in Italy. I don't really want to do that as its going to cost megabucks. Dose any one know were i can get the tool from?

Thanks again.

that's BS. No need to ship them anywhere. You just need these special sockets - and a new camera for better pics
I cna check with my parts supplier what the exact price for such a set is if you like.
I may know another (cheaper) solution as well. Just send me a PM.
Cheers
Wolf

camara is awful (its a nokia 6230 ).

Ive been tempted to bash a socet over the nut on the back & wind them off that way, but A i dont want to ruin the bolt incase i cant get any new ones & B im a little bit scared.
