Has anyone installed the stock W204 17's on their w203? I would like to know where you may have bought the spacers/bolts and what specs I need to get?
I wasnt able to find anything really conclusive with the search but if anyone knows of a past thread that has the right info let me know please
Thanks guys

that works for the spacers (a lot more expensive than i thought) thanks
but the bolts I need should have a larger seat but the same 12mm thread according to another thread.

Wardsweb

I use 15mm spacers from H&R and 12mm x 1.5 x 40mm R13 lug bolts to fit both the seat on the wheels and the thread on the hubs. I got them from RAD USA Direct that is now http://otisincla.com

Thanks, I actually found the european site for RAD and they told me I should get the r14? But everyone here says the r13 is the correct one so now I'm stuck between the two :s
Are you absolutely positive about that r13?
I also bought 10mm spacers because the oe offset for the w203 wheel is et37 with 7 or 7.5 wide (depending on optional wheel or not) and the wheel I have now is 7.5 with et47. So do you think that will do?

Thanks for the help

C-class (W203/CL203) have two bolt sizes:
-long- M12x1.5 thread, R12 ball seat, 39.9 mm shank, 17 mm Hex (for OEM alloy wheels)
-short- M12x1.5 thread, R12 ball seat, 20.6 mm shank (for winter "steelies")
W204 have one bolt size:
M14x1.5 thread, R13 ball seat, 26.7mm shank, 17mm hex (for OEM alloy wheels & winter "steelies")

Can someone please help me out?? I have the stock 2009 c300 wheels and want to put them on my 2004 c240. I have purchased 10mm spacers for the offset but don't know what size bolt I should get? Any help would be greatly appreciated. Thanks.

Personally, I don't see why you're doing this, but make it easier on yourself and do a stud conversion. You'll never have to worry about lug bolts again, and it's pretty simple. It'll also save you money on not having to keep buying different lengths constantly.

Thanks for the response tommy, but can you tell me how I can do a stud conversion? Thank you.

I could just tell you to search, but that wouldn't be nice.

A stud conversion is a set of headless bolts that you tighten onto your hub like you would lugbolts (blue loctite applied to each). Then you need to get lug nuts that work with your setup - tapered (most aftermarket rims) or ball seat (MB rims), and you're good to go. you can then change rims, spacers, etc. as much as you want without need of worry about anything except fender and brake clearances.

I got my set from Rogue Engineering here in Jersey (same thread is used on our cars and most BMWs), but others have gotten theirs from other providers. About $70 - 100 for a set.

Thanks Wardsweb. This is good information.
