Would magnesium Minilites differ in material thickness or geometry? Otherwise even a lighter Mg Minilite is not an ideal replacement.
The Teamdynamics rims do not look too bad, very functional and clear design without flourishes. I like them, could "work" on a P4SS, but a bit close to the bone concerning what a Morgan stands for, otherwise good value for money. Similar looking wheels are on my Elise (wheels from 2009 Exige Cup 260 series). Would be ok if I would use her mainly on track days.
Regarding the looks I fall in love with Turrino painted Alloy spokes but next week will see how much money they want, I guess very expensive...could find nothing in the web regarding prices, found only an old price competition "win a set of Turrinos" value 5000GBP. That hurts.
