Edwin, I really prefer stock wheels also. I actually like the way the original 1990 wheels look. But I also really like the A-molds on the car now, and I love Dymags. Plus, this keeps the originals in nice shape.
I'm not sure if these ever came on a Callaway SuperNatural car. They mostly used OZ wheels like this (seen on one of the two amazing twin-turbo LT5 Super Speedsters):
It's possible some ZR-1's had the Dymags. Callaway did a lot of custom type stuff, so every car was somewhat different. I don't know.
I believe the Dymag's are a few pounds lighter, but the A-molds I have now are pretty light too, lighter than the original wheels.
The guy selling them is offering them for $3000 shipped. Dymags from Callaway new sell for I believe $1800? That's for the 17x9.5" wheel the TT had. It's hard to say how much the 17x11" was. I heard MidAmerica used to sell them for $950 per front and $1150 per rear, but not in gunmetal, just in the original "aluminum" color. Plus, these have matched center caps, the centers on the original Dymags was the factory machined look since the non-Callaway wheels were a machined face. I always thought it was odd to have the center not painted to match the Dymag.
Anyway... it seems like a fair price, Dymags are fairly hard to find. And he has the Low Tire Pressure Warning Sensors mounted to the rims already.
I'll have to think about it. I'm not sure I'm ready to drop $3k on cosmetics, though I do need new tires anyway...
