Sometimes those "ultra light" wheels are to flimsy for street use -- I'd be cautious. They may not have the strength for high lateral loads or if hitting a pothole.
The MT wheels do look nice, though.
You might also check out Centerline "Convo" series wheels. They are street legal and weigh in the low 'teens of pounds .
Louis Lopez runs them...I have a set that are going on when the motor goes back in. I think I have a picture of his car with them if you want to give me your email.
