You couldn't by a E92 with a non-CF and non-moonroof. (so was it 45lbs over a moonroof? or a comparable standard E92 non-M3 roof?)
My understanding is that the 45lb weight saving of the CF roof is compared to a moonroof equiped car. Apparently the CF is worth about 15lb compared to no moonroof steel roof.
