I have a 2007 G35x and just got the Stoptech BBK part numbers are for the RWD model.
Everything fits EXCEPT the caliper brackets, on my AWD the bracket holes are farther apart.

Any ideas or suggestions if there any any universal brackets I can get?

I looked at the stoptech website and they dont have anything specific for the AWD so I dont know if they will have any info when I speak to them.

Any other AWD owners make the BBK upgrade?
