My 2012 already had the factory rails on it, so I'm looking for a crossbar solution that's beefier than the 100lb Mazda bars. Holo is your 460R solution using the roof rail mount points or do they clamp on the factory rails? What's the load rating you're getting? I'm thinking of heading down to the Rack Attack brick & mortar store to talk to the sales guys in person and get their recommendation.
