Atenza GJ / Mazda 6

ATENZA: OEM Roof spoiler arrived

I never had big plans in modifying the Atenza, but somehow the Optional OEM / Mazdaspeed (depending on the catalogue you look at) bigger roof spoiler has been floating around in my mind for a while, so when i saw a new one for sale for a good price i went and grabbed it:

i made a little test-mockup too. Before (Standard roof spoiler)

New bigger one. needs to be painted before installation, of course…

Now this is not only a styling-item but also an useful thing. Since i drive my car mostly on the autobahn from and to work this might come in handy. According to the 2015 japanese Shop options / Mazdaspeed catalogue it will increase aerodynamic stability and balance at highway speed and reduce the drag coefficient by 0,6% the front lift coefficient CLr is improved by 20% and the rear Lift coefficient CLr by 60%. this might also further improve the (pretty good, in my opinion) fuel economy, which comes as a bonus… we’ll see..
