Please post pics of the new 08 Split Spoke Wheels in CHROME.
I would really like to see em on a MR or Crystal Red Vette if possible, but on any color will be appreciated.
Hello
I have (1) set of Factory Reproduction C6 Sizes Factory Offsets 18X8.5/19X10 Chrome Split Spokes with center caps & lugs for $780.00 Delivered. Your stock TPMS will fit.
Regards,

Well that seems like a good deal but I went back and re-read this thread again and someone stated that GM never carried the split spokes in chrome is that true? If so, what was their price for them?
Yes, this is true GM Does not offer the split spoke wheel in Chrome.
The GM silver split spoke wheels are getting Chromed, and are sold for $400 - $500 more than the split chrome reproduction wheels.

Hello
Nevre heard of how chrome could hurt a wheel. As for weight the chrome adds about 2 lbs. I posted the actual weight back in November and will see if I can find them. If someone has stock wheel without tires let me know the weights and I will weigh the ones I have in stock.
GM won't chrome the OEM splits because they say there is not sufficient strength after chroming. I doubt the after market wheels are any stronger.

Aluminum alloys are susceptible to hydrogen embrittlement, although the face centered cubic microstructure means that the transport of hydrogen is slower than in high strength steels, and hence the crack growth rate may be lower. The cracking is normally intergranular. As with steels, the susceptibility becomes more severe as the strength of the alloy is increased. Any environments that can provide hydrogen can lead to SCC of susceptible alloys, ranging from humid air to salt solutions (used in plating)."

Your information is not correct. GM requires significant evaluation and testing before they will approve a wheel for production. They were worried about strength and possible failures after chrome plating these wheels due to the spoke design and dimensions. That does not mean they will crack, just that GM was concerned about the possibility and decided not to play at this time.
Just curious and not trying to be a smart a$$ but do you work for GM, on their wheel R and D team, or know someone who works in that area? I ask this as you seem to offer a lot of interesting info regarding chroming and GM's take on it. Or, is this just your personal knowledge on this?

I'd be surprised if there was any significant difference on painted vs. chrome OEM's since the paint is applied about .006 thick and plating around .004. All bets are off for repo comparisons to OEM.

The concern regarding hydrogen embrittlement for chrome plated wheels is minimal with current aluminum alloys, casting techniques, and plating processes. That doesn't mean your explanation is incorrect. However, I would lean toward the idea that the painted wheel tends to push customers toward an $1800 upgrade, while an optional chromed version of the split spoke would be a tough sell at that price.

Not to disagree but GM has been known to make bad decisions in the past, I'm sure you are aware of the polished C5 thin spoke rims and the major problem they had of cracking. All cracked Rims that I saw were stock OE polished and regular thin spokes.

Dang this info makes me afraid to go over a 100 MPH with these wheels under me.
