An article I found on Racer.com says F1 is set to ban FRIC suspension systems. The gist of the article is that Mercedes is using a FRIC suspension system, which was originally used by Lotus/Renault way back in 08. Mercedes have since perfected it and this could very well be the reason for their performance this year. F1 wants to ban its use before the German Grand Prix, but without adequate testing time, it may be a bad idea. Teams will vote if it should enacted prior to the German race, or at the end of the season.
