Living outside of north america and trying to get info on repairing my Mars has been impossible. So in case this is new information to anyone, Oakley U.K. still offers a tune up deal for Mars. Gotta ship them there, and have a U.K. contact to receive them for you and forward em on, as the U.K. office won't ship outside of Europe. Tried Japan, U.S., Canada, malaysia, Hong Kong and China, and this forum, all no dice. So, 12 year old pair of mars tuned up and tightened, new set of linegear lenses and I am happily sorted.
