The stock bonneville silver crosslace wheels that are dark between the spokes are 17.4 lbs.
The gold centered crosslace GP wheels that are 8" wide (early 90s) are 22.4 lbs.
Both had valve stems too.
Just posted for any rotating mass **** to find.
Add others if you know them for sure.

Wow. I always thought my CL'* were 21 pounds. That'* good news. I know they're the lightest KNOWN OEM wheel we have here.

Yup... I just threw one of my very dirty grey painted 16x7 crosslaces on the scale and sure enough, 17 lbs is what it showed (doesn't show tenths).
I also set a gold edition 1997-2000 Grand Prix 5-spoke on (16x6.5) and it came in at 16 lbs.
The 2002-2004 Chrysler 300M SPECIAL 18x8 rims I have came in at 24 lbs.

Jeebus that'* pretty good..

I'm curious as to how much weight the gold coating adds though. I just picked up a set of those gold 16x8s with the intention of stripping them (I've read about how tough that is) and painting the center black. I'll be sure to weigh a wheel after I strip it. It might give an idea of how much if really any weight is added with the gold coating. I know on the older BBS wheels it makes a difference.

I can't imagine that gold epoxy coating weighs more than 3-4 ounces.

The silver painted one I weighed are like the gold ones only painted silver (same as Jason'* and Pat'* 93 SLE'*). It weighed in at 17 lbs (my scale doesn't show .xxxx'*), so if the crosslace you weighed in at 17.4 lbs was a polished face with the grey/blue metallic inset then the painted rims can't weigh more than a couple ounces

JDB weighed a crosslace for me once. Can't remember what color or weight though.
