EDIT: RC041 not rc010.. doh!

Will the bolts from the RS's be ok to use on these. I know they're not splined like the RC bolts. These are available and I can't find any for the RC's.:)

Can you post up a link for the bolts please Stu, I know they have to be splined where they press into the wheel, but just want to see them first...:thumbsup

New bolts are a must when these wheels are split. The problem with them is that they corrode into the wheels and need hammering out, which takes fookin ages...:hihi

Give these guys a ring and see what they recommend http://www.justmatz.co.uk/

TBH I was just going to use the RS bolts as they are only supposed to be torqued to 20nm IIRC

Cheers for the link mate, I'll get in touch and see what they say.

I defo need some new ones, just been faffing about with the old ones and 18 of them are totally fecked. Been googling and it seems some people have used them (RS bolts) but can't find anything recent (maybe they all died..). I can't see a problem with it, it's not like the centre can move anywhere and the bolts must be strong enough. Mmmmmm.

Those bolts were all I could find as well. Im gonna use all new chrome ones, I dont want to reuse the bolts as they need to be hammered out. Also saves the bolts rusting after all that work on the wheels. They are just so bloody expensive...:frown

I've used this place before for all BBS stuff. They've been very good so far with no problems.

Their price for 80 bolts at todays exchange rate come out at about £97 plus shipping. You will need to check the price against what they charge for the conversion and shipping though.

There is no point in using non splinned expesnive BBS bolts where spline bolts are fitted. You may as well just use any flange head bolt to do the same thing at a fraction of the cost. You won't get the same bolt head style, but if you look on eBay someone is doing the same with button headed non-spline bolts for the Style 5 BMW wheel which also use the same spline bolts as the RC040's as a cheaper alternative to the expensive BBS style bolts.
If you do go the non spline way, make sure you use some good thread lock on the nuts because if the nuts do come loose the bolts will just fall out very easily.

Surely these would have to be high tensile? They are holding the weight of a large car and the accociated forces that go with it. :)

What you also have to think about is that non-spline bolts wont be a tight fit. You could take the nuts of a used set of RC's and getting the center to come out would take a beating with a big hammer and a block of wood.
Now imagine you replace with bolts with only a clamping force to hold the rims together. Add in the fact the RC's use a lot less bolts ( 20 rather than 34 per rim I think ) than RS and Style 5's and you might now be able to imagine that if any of the nuts start come loose you can be in for a big problem.
Being able to fit different bolts doesn't mean it's all OK. The truth is I don't know and nor does anyone else really. You are on your own here, so if you do go that route make sure you those nuts have no chance of dropping of.

Good point. However the splined part of the bolt only goes through the rim, not the centre and it's not a tight fit on the holes on the centre by a long shot. The wheels are probably so hard to split because they've not been apart for years. If the nuts came off after them being apart, even with the splined bolts, they wouldn't stay together anyway. I may go for some high tensile bolts. The only problem being that I can't find any that are plated, apart from zinc plated which I think would corrode after a time. :)

was reading somewhere todasy cant remember where but stainless should be ok as long as it is 8.8 tensile or whatever ... and as above the reason they are so hard to split is nothing at all to do with the bolts as you remove the bolts before splitting ????

Yeah, I seen the same on wheel-whores. Can you find any s/s bolts that are 8.8 or above? I can't! :)

Nice one, let us know the results. I've been looking into this, an 8.8 alloy steel bolt has a tensile strength of 828N/mm2. A stainless steel A2 grade bolt has a tensile strength of 700N/mm2 and the A4 grade of stainless is 800N/mm2. Both are below the alloy steel bolt. I've also that read that the s/s bolts are suitable for bodywork etc but not load bearing parts of a vehicle..
I'm gonna get some 10.9 high tensile bolts and nuts with a button head and see if I can paint them before fitting, do them up, then touch up any paint I've buggered up in the tightening process..
With regards to the wheel-whores thread saying you want M7 bolts, yes the original thread is M7 but M8's fit snug in the holes without rattling about, plus they're more readily available than the m7's. The bolts and nuts that I'm looking at getting are £41 all in for 80, would be better if they were plated though...:)
