Most of the RS stuff that the package comes with can be bought later, at your own pace, and it's more affordable that way. I don't have 19" wheels, I have 18" wheels and they currently have BF Goodrich tires on them. It's my intention to get a full set of 4 winter tires (mounted on wheels already) at a 17" size as they cut a narrower path through the snow and get you through it better. Those tires will likely be Bridgestone Blizzak.
I don't know if you had the right person that you sent the message to, but hey...from one Camaro owner to another...I don't mind hearing from anybody. Also, thank you for liking the look of my car Take Care.
