The rotors are a down spec though so don't really like that idea :/
Don't really know , depends on what it is !! Lol
Personally id stick with the stock wheel, it was Designed by Audi's Quattro division so wasn't just chosen off the self because of it looked ok - alot testing went into making sure it was the right wheel for the S1.
Do you have any photos of them on your car?It's just a wheel, apart from size, offset and weight there is no difference to any other wheel that you can buy. The Ultraleggeras that I bought for my car are stronger, lighter and half an inch wider. Do your research and get size and offset correct and you will enhance the car's handling with them rather than hamper it.
Thank you for the piccies.
