For those thinking of using wheel spacers:
20mm on back and 17mm on front are definitely the way to go. They give just enough presence without being over done. Do not go less than 20mm in back or you will not get the right look.
The handling is also greatly improved. The hub centric spacers & extended bolts are required.
I found a great resource for them as well $$$ if anyone is interested.
They are easy to install and well worth it!
