Style 42 split rim bolts

[d2d101]

Hi,

I have posted in the wanted section for used or new bolts to fit 17inch staggered style 42 split rim (36111094373 and 36111094374).
I checked and BMW doesn't have a part number for the actual bolts. The bolts have BBS stamp on it, so it makes sense there is no BMW part number.
Does any know what are they made from (Titanium??) and can they be sourced new?

Thanks

As an update I contacted BBS who were brilliant and replied quickly. The wheels were a private label commission by BMW which means they have no data and if they did have data they couldn't provide it. I have reached out to BMW UK.

I see a set of 100 (for 5 wheels) for £275.00 plus vat and postage!! They look like the correct ones but not totally sure they are the correct ones.

My dad's had these on his Z3, very soft .metal i found and difficult to get off when seized.

Never seen any advertised new for sale but I'd reckon BMW will have a modern replacement on their catalogue.

Personally ive took mine off. Alloy wheel theft ain't what it use to be and im careful where i park # Fingers crossed!!

You might be thinking of wheel locking nuts. I am looking for the bolts that hold together Style 42 BBS split rim alloys that BMW sold as an option on the Z3. Not sure if the bolts where used on other BMW split rims.

Try https://www.srrhardware.com I got bolts for RC041/2’s from them.

Best techniques to loosen them are:

If corroded - to heat the barrel hot as you can, chill the bolt head and smack whatever bit fits hard with a hammer to shock the bolt loose.
If not too corroded, smack the bit with a hammer a couple times.

As soon as it moves at all, stop, drown it in lube and slowly unscrew. If it gets tight, add more oil and slightly retighten. Working it back aand forwards will then get it out.

Do wear safety glasses and definitely earplugs, or defenders, the wheel will ring like a bell when you strike the bolt.
