No, the roof rack doesn't add much noise at all. The slats are aerodynamic so cut through the air pretty well. I will look at getting a removable basket for when we go camping.
Yeah. The black rims did end up looking good. Add a little more presence to the car. Everyone I talked to asked why I was changing the standard 18" rims which are very nice until they saw the black ones on it. Thankfully in Australia we don't have to worry about winter tyres
