Sheesh, what a long name these things have. I'm going to install some OEM cabrio strut tower support rails tomorrow. I know (or think, at least) that there's hardware in place in my engine bay already (2005 R53). But can anyone tell me what the thread pitch and approximate bolt/screw length is? I'm guessing M8x1.25? Save me from pulling the things out in the cold right now... I'm enjoying my warm cup of coffee.

 

For anyone else who's curious... My car did NOT have any hardware, nor all the holes. I'm missing one of the lower holes on the driver's side. Is this normal? The hardware, in any case, is all M6x1.

 

And again... Turned out I'm not missing any holes. It's all good. I needed a massive extension and universal to get around some of the wiring on the driver's side, though! What a pain... But they're in! I installed 5mm head M6 bolts with fat washers under them, for what it's worth.

 

Thanks for posting the details. I have a 2003 (no holes) with the front disassembled & am considering fitting these

 

I had a 03 MCS before and had them drilled to fit. The 06 GP was easy, the screws that came with the cabrio bar went right in.
