Greetings -
I just purchased a 2007 BMW Z4M Roadster. I am replacing the stock wheels with OZ Ultralegerra 18 inch rims, painted black. The lug bolts that ship w/the OZ's from Tire Rack are chrome, so I ordered black lug bolts from Turner Motorsports.
Here is where it gets interesting....
The front rim offsets are nearly the same:
Stock: 42mm
OZ's: 40mm
If I use stock length lug bolts (the black bolts from Turner Motorsports) will the bolts be too long, or too short by 2mm? Do you have a black locking lug bolt in the appropriate length? If not, is there a plus or minus factor that allows a 2mm (too long or too short) factor?
-------------------------------------------------------------
The rear rim offsets are different:
Stock: 30mm
OZ's: 40mm
Tire Rack stated I need a 20mm spacer to ensure the wheel assembly is back in the exact same location as the stock wheels. Pls offer your comment on this. Also, do you have a black locking bolt in the appropriate length?
If you just have chrome, can you apply the black finish, so I have black finished lug bolts on my new OZ black wheels?
stock 18's:
front: et 42
rear: et 30
oz 18's:
front: et 40
rear: et 40
O.Z. Ultraleggera
Finish: Black Painted
Front Fitment
18x8
Offset: 40mm
Backspacing: 6.10"
Bolt Pattern: 5-120
Rec. Tire Size:225/45-18
Weight: 18.6lbs.
Rear Fitment
18x9
Offset: 40mm
Backspacing: 6.57"
Bolt Pattern: 5-120
Rec. Tire Size:255/40-18
Weight: 20.8lbs.
Thanks very much - my new OZ rims arrive appx 15 Apr and I want to install on Fri 16 Apr, if possible (with McGard locking lug bolts, of course) (:
Thanks very much - pls call and/or email to:
