Be advised they are of a much softer alloy, are prone to bend and crack easily. I know because I and others, JWise, have been wrestling with these issues on the sets we purchased used. I'd stick with the stock Cup II GTS wheels. They are strong and fit without concern.

With that said, I am looking for a second set of the 18" Mille Maglias for my other car. I'm willing to to buy them despite the issues stated above. I know I will need to have them trued, cracks rewelded and painted/powdercoated. These I would use for easy driving.
The OP didn't say anything about Cups. Based on the sizes he quoted, they are the Turbo Twist type as used on the 993, 993 Turbo (hollow spoke type) and early 996s.

I have never seen 18" Cups (ie. 5 spoke alloys like the ones shown lower down). I don't think they exist. Mille Miglia produce replicas, they don't as far as I know do any Porsche designs in sizes that Porsche themselves didn't do. Offsets maybe, but not sizes. ETA: Bugger me they do:

Also, FWIW, I've never had any quality issues with Mille Miglia. You guys do know that a lot of the factory-fitted Porsche wheels are made in Italy?

I've never understood why the vast majority of posters on here seem happy to fit wheels with the wrong offsets to the front of the 928.

Probably because short of having $3000-$5000 3 piece wheels custom made, there ARE no other wheels that match a 928's offsets. I understand it's a supercar, but of all the cars I've owned and all the forums that I've belonged to, this is the only one that's worried about matching offsets to the letter. 2 BMWs, RX7s, Fords and Dodges, the question is "Will it clear, and will it rub". Here it's like "Oh, it fits and works, but the offset is off by 5 millimeters so I wouldn't use that on my car! (Yes, wheel offset is in millimeters, so the difference between a 60 offset wheel and a 50 offset wheel is 1 cm.)
