will BBS CH's work on da z?
 

...just curious

YES

Works pretty damn well IMHO ;)

Too bad those aren't CH's on the Mine's car :icon18: . Regular CH's are cast and aren't as good as the forged (lighter and stronger) version.

These are forged wheels and the offer fitments specifically for the Z.

However, If you really want to go for the look and the performance and you dont have a big brake kit in mind you can go for the classier IMHO RGRs. These are forged and are at 18 pounds for 18" however I have heard from the M3 board that they do not fit on the car with a brembo BBK. You would need a 13mm spacer which would put the wheel too far out the fender. I am not sure if this is the case with the Z and the stoptech or other BBK out there, and am not sure if they even work with the track Brembo's. Very good looking fat lip mesh wheel for a 1 piece forged.

To get the diamond silver as shown you would need to find a grey market importer of BBS japan wheels like www.wheelexperts.com The can get you any size or finish you need with a little waiting involved. You would definitely be one of a kind with Japan Spec BBS on your ride.
