Thanks.
No way carrying extra weight without function
Back seat is in place for hiding the audio (future plans) and sound isolation purpose. Though I'm pretty sure you will find no passangers on the rear bank, but it is still nice to have access to the battery area or throw a bag there. On page 3 you find pics about the Wiechers seat consoles i am using, they are designed to pop the seats forward so there you go.
I was told they were Recaros but can't prove that as i could find no signs at all. Bought them in Germany (from a nice BMW2002), maybe they are vintage Konig or Wiechers ones.
However they are bucket seats the back is still adjustable in a 0-15 deg. range that's why you can see the adjuster on the outer side. Might be useful during a longer trip. They weigh only 6 kgs each, way less than the previous Sparcos (recliner) did.
