Another mistake by the manufacturer could be your gain !! One set of 20" Mesh8's are now available at the year end inventory adjustment pricing. This could save someone a lot of time and money. Already machined for a C6Z, and could also be used for a new CTS-V.....2009/2010. Please PM us if you are interested......20" only with any width to 13.5; staggered, any standard finish, full warranty, guaranteed fitment, all new parts. The centers are in the warehouse , not a figment of the imagination.
This is worth your time, if you want a premium product at a very fair price. A trouble free fitment, with several 100 sets of these sold over the past 2 years.
Thanks for reading.....
