I installed on my car early this week a new set of M580 20" wheels from
GetYourWheels. They're powder coated in Brushed Stainless, which is a cross between silver and gunmetal. getyourwheels was an enormous help with the order and my hat's off to him.
The wheels are shod with 245/40R-20 Pirelli Cinturato P7 All Season Plus XL, which will be the basis for my experiment with sound deadening foam to line the tires. Once I get a enough baseline sound meter readings without the foam, I'll receive another set of the same tires lined with the foam from the manufacturer in Brussels.
I can use the 20" wheels year round but I will put my OEM 21" wheels on the car when the cold weather fades away in the spring.
Here are a few photos of the wheels. I think it's a more aggressive look than the turbine wheels and I'm pleased with their high quality, finish, and appearance.
GetYourWheels was great to deal with. Stays in frequent touch about the order and shipping. The service could not be better.
Thanks!
