[Z06] 2001 C5 Z06 Considerations
The Best of Corvette for Corvette Enthusiasts
The 2001 and early 2002 M/Y Z06 Alcoa forged OEM rims :
17x9.5 #9593803 & 9593804 fronts weigh 19.6 lbs
18X10.5 #9593805 & 9593806 rears weigh 21.4 lbs
The early/mid 2002-2004 M/Y Z06 Speedline spuncast OEM rims:
17x9.5 #9594808 & 9594809 fronts weigh 19.2 lbs
18x10.5 #9594810 & 9594811 rears weigh 21.0 lbs
Bowling Green continued to install the Alcoa rims onto the 2002 M/Y Z06 till supply ran out.
2004 Z16
The rims that came on the Z16; fronts #9595433, rears #9595434 I could not find recorded weigh.
The 2001 forged Alcoa rims are slightly heavier than the Speedline spuncast rims used from 2002-2004.
My answer to your specific question is that the 2001 Z06 is a milestone car for GM. Even with the stigma of disinformation and urban legend and the fact that the 2002-2004 Z cars are slightly more refined, the 2001 Z06 will hold its own in the market place.
My 2001 Z06 is a great car ( that I have upgraded with 2002 Z06/LS6 parts). I don't plan on selling any of my C5s ( two 2000 FRC and 2001 Z06)ever, so resale isn't a factor for with these C5s.

My 02-04 Speedlines coming lighter than virtually all the posted weights, they vary to, but between front to rear they come in generally .7-1 lb lighter. (For instance, the rear 18x10.5" Speedlines are almost as light as the front 17x9.5" Alcoa's)
All that to say, in my experience, the 02-04 Speedlines are closer to 3/4-1 lb lighter per wheel than the Alcoa (which is more than the posted specs I've always seemed).
It would be interesting to know what the actual load ratings are for the forged vs spun cast.
The 01's get a (unjustified IMHO) bad rap, and the prices can/do reflect that in the marketplace, but it's a great way to get into the C5Z06 world and for less $$.
Exactly. The difference in value between now and the future will pretty much be the same between an '01 and '02-'04. It is worth slightly less now, and will be worth slightly less then. So there is no reason to worry about buying an '01 due to poor resale.

"The ’02 Z06 wheels are a tiny bit lighter and made by a different supplier using a new process but they carry over the "old" look."

"We like this because we can get better throughput, which we need to be able to build more Z06es, and we’ve been able to take some mass out. A set of Z06 wheels is .7 kilos (1.5 lbs) lighter than 2001 forged wheels. That’s a tiny amount of mass, but it’s in the right direction. In 2002, the painted (base) wheels and the Z06 wheel will use this cast-spun technology. It really is the next, new technology that’s the best for making a Corvette wheel."

















mine has almost 100,000 on it going strong
