I appreciate all the effort put into this video. This just goes to show you that GM did a great job making these wheels as light as possible. The 17" magnesium weighing in at 17lbs is still very impressive as a wheel and the Z06 wheel even more so. A 17x9 Rays gramlights 57cr weighs in at 18lbs! So all of the C5 wheels are pretty damn light as far as wheels go. The real weight savings come from not running, run flat tires. My wagon wheels with the OEM Goodyear run flats weighed in at 49lbs for the 17" and 53lbs for the 18".

You put a lot of effort into this. It sounds like the factory Z06 Speedlines are the lightest!

LoL...Like the Opti just hanging around watching you make the vid..great vid man

Huge surprise for me!

The stock wheels on my sport coupe 370Z were 19 x 9 & 19 x 10, made of forged aluminum and weighed about 23 lbs. I bought a set of Litespeed Racing forged magnesium monoblock wheels of the same size that weigh about 14 lbs. The difference in handling is quite noticeable, with better steering response and better suspension dynamics. The wheels not only lighten unsprung weight but also your wallet, to the tune of $3k each.

Ironic. I just bought a '99 FRC in Puter. I really think these will be noticed over time as the "first ones". No HUD, limited options, low production. Anyway, I like the wagons and trying to keep it stock, but the mags will look really nice. Great, easy going presentation. In a good way, can't believe I watched this full :30 vid! Keep up the good work!

That’s awesome but make sure you drive the car and enjoy it, these cars are so much fun and I hate seeing them sit for “investment money”

I use a layer of anti seize compound on the mounting surface of the hub with the wheel to reduce the possibility of corrosion. I think you could have gotten a better engineered wheel that would have weighed less. Specifically, having very thin spokes in the shape of I beams with additional cutouts in the spokes for more weight savings. My recommendation would be to use Michelin Pilot Sport 4S or Cup 2 tires for even more weight savings. My 370Z with 19 x 9 Litespeed Racing forged magnesium monoblock wheels with Michelin Pilot Sport Cup 2(240) tires comes in at 37 lbs total weight.

Didn't see where anyone answered your inquiry about the width of the Z06 rear wheels. They are 10.5 inches wide. Enjoyed the video. Thanks!

My 2K Coupe has the stock painted thin spokes, this is good as I think they are one of the best looking OEM wheels ever produced. I am in process of a stroked LS3 build expecting 650 rwhp but also want to keep it as sleeper looking as a Magnetic Metallic Red C5 can. I put rears on all four corners and I am thinking about having the rear ones widened 1" to squeeze some big meats in there. Great video, you got a sub from me.

This video is great and much needed testing! Now I'm curious about the C5 Z06 Speedline wheel weights vs the original 2001 only Alcoa wheels! Especially since they are made in the usa I believe and they're forged and weight a bit more than the Speedlines from what I've heard!

My 2000 C5 Corvette convertible 6 SPD Manual has the magnesium wheels MSRP $4500 discounted price to $3500 with the Goodyear run flat tires which were standard. Per the Corvette museum there were only 264 ordered. Which puts it on the rare list. Double coat of Millennium yellow and clearcoat option was $500 .. The double coating had only 255 ordered. Light oak convertible top and electric sport seats was a no cost option. These three options put the car on the most rare list with the Indy Pace Corvettes ...

The lack of popularity and gradual decrease in price of the magnesium wheels is identical to Quadrasteer with the GMT800 trucks. From $7,000 in 2002, to just $1,000 in 2005, it wasn't even available for 2006.

I bought a set of 01 Alcoa wheels for my 02 Z the other week, and they are noticeably heavier than the Speedlines that came with the car.

BTW, I have 2 sets of the Mag C5 wheels so I can have 17s and/or 18s on all 4 corners on my 383 LT4 Camaro Z28 (More on that later) Back in 2006 I ordered a set of aftermarket 18 inch C6 wheels and tires that weighed in at a total of 210 pounds all together. When I swapped on the C5 Mag wheels and tires, the weight came down to 150 pound in total. That's because I made sure that I ordered the lightest tires I can find that are in the ultra high performance all season category. Summer time or extreme summer tires would have been a little more heavier but my Z28 handles pretty dam good with the all season tires. Also to further reduce weight, I ordered up a set of titanium lug nuts (highly recommended just because they won't corrode not to mention there almost 2 pounds lighter then the chrome lug nuts)

If I install the C5 Magnesium 18s with 275/35/r18 tires, my wheel and tire weight would only go up by just 8-9 pound using General Gmax AS05 compared to my 18 inch C6 wheels. BTW the tires on my C6 wheels are only 255/40/R18s.

Also take into consideration that the old 295 tires on the Z06 wheels have decent ware on them which will lighten them up a pound or 2 depending on whoever owned them before and how many burn outs or just plain mileage the tires have been through. It's been awhile but I'll check out the tire weights on the old eagle supercar tires unless tirerack no longer carries them which means the info or specs are usually gone also.
