Just another detail that trackers will appreciate. Aggravating to lose your wheel balance after the first session and then be running on "square" wheels. Once again kudos to GM from a person who understands and appreciates what they did with the Z/28.

I know what you're saying but I remember reading something about the Z/28 wheels being knurled. It was posted here a while back. I guess they could have changed from knurling to blasting if it was cheaper.
