20011 aluminum wheels question
Are the 2011 factory aluminum wheels (painted, machined or chrome) forged or cast wheels?

The wheels that are made by Speedline(my Z06 spiders are) are low pressure cast in a permanent mold. About 30% stronger then wheels that are gravity cast with the same dimensions. I don't know if all the current OE Corvette wheels are made by Speedline though.

My understanding is that the only forged GM wheels for the standard-body Corvette, were the 2008-2010 Gumbys, chromed or polished. All others are cast, but i don't know which casting process(s) they used. Not sure about ZO6/GS.
In theory, forged should be stronger/tougher. But I've seen C6 wheels locally that hit a pothole big enough to damage the tire and dent the rim but the owner simply bought a new tire and had it mounted. Rim has not shown any evidence of cracking or further deterioration. I wouldn't do it that way, but it's not my car.
