A friend of mine just bought a 2010 camaro with 21 inch factory rims. It came with a 18 or 19 inch set of standard rims (5 spoke). I am considering buying them off of him. Question I have is - will it fit my 2006 GP base model? I am not sure if the bolt pattern will be the same or not, but I am guessing the bolt pattern should be the same. I know the GXP models come with 18 inch rims, so if anyone knows anything about it or if it's possible, please let me know. Thanks in advance for any info.
