The quality of RR is 5 star in my opinion. Respectable weight, very sturdy, rough texture. They screwed the mount onto the side panel, so there's no wobble (see photo). Not sure how the wind noise would be without the lowering kit, but from what I experienced so far, nothing out of the oridinary regarding noise.
