PCD on Z4?

Can anyone tell me what exactly is my PCD (I think its called that) is on my 2005 Z4? Its the 2.5SE model if that makes any difference.

If PCD is incorrect I mean the bolt pattern/distance thingy... :roll:

I am looking to put some 1 series M sport wheels a mate of mine has spare onto my car. I think the part number is 261M.

Thanks in advance.

Pitch Circle Diameter. It is the diameter of a circle that would intersect the centreline of all 5 bolt holes. PCD is 120mm on the Z4
 
Equally important is to know the offset, backspace of the rim to see how far in/out it sits relative to the original rim.
Rim diameter to ensure it clears your calipers (you don't specify your model, but unless a 3.0Si 17" min)
Rim width for compatibility. 8J, 8.5J if you have a staggered set up.
 
Sorry to be a boring git but could do with an answer pretty soon as I have to make the decision to drive 130 miles to go get them :driving:
 
Can't help as I don't even know which model Zed you're driving.

Post on here rim size in inches and offset and I'm sure someone will tell you if they'd fit

Personally I'd not be fitting narrower front rims than standard on the car, albeit it only 1/2" less
 
Cheers Cj. My Z is a 2005 2.5SE model, I dont know what else to put really?

The wheels that I am looking at are as follows

2 x 215/40 R18
Front - 215/40ZR18
7.5J x 18, Offset 49, 5 stud, diam. 120,
Part No 7 891 050

2 x 245/35 R18
Rear - 245/35ZR18
8.5J x 18, Offset 52, 5 stud, diam. 120
Part No 7 891 051
 
That's exactly the information that is needed to confirm.
Certainly the 18" that you're looking at would fit any Zed. 17's would fit yours.

Tyres are narrower than a stndard staggered set up, but not much

Offset is all you need to investigate now to see how far the wheel is in/out relative to your current rim. That will tell you if it will touch the suspension or protrude out the wing.
 
Those sound like 1 series wheels - with the offset and tyre profile.

They will fit, but you will need spacers to push them out and they will be sunker within the arches, more then stock... Also as CJ points out a they have a lower rolling diameter then stock - so will knock out your speedo out slightly (but imo not a problem) and will make the gap within your wheel arches look bigger.
