    Interesting problem for Mercedes. Similar attempt at innovation hurt Lotus last year. Anyone mind explaining the benefits of pull rod over push rod? Why was it abandoned for so long and what has changed to make some teams consider it again?

    Red Bull's been using pull-rod on the rear since 2009. The use in the rear is different than what Scarbs reports for the front. In the rear, it's to make room for the diff and the diffuser, so they can have the best aero shape. Scarbs talks about Red Bull's use of it, as well as more generally, the advantages and disadvantages of it:

    http://scarbsf1.com/blog1/2011/04/07/red-bull-pull-rod-suspension-detailed/
    http://scarbsf1.com/blog1/2010/10/1...t-is-looks-like-how-it-benefits-aerodynamics/

    The year that Brawn won the championship with its double diffuser, the Red Bull was pretty notable in how wasp-waisted the rear of its body work was --- it looked like it went down to a point at the rear, and was much more elegant looking than the rest of the field. The RB car was also the only car that could keep up with the Brawns.

    It's "pull", because when the wheel is in bump (ie. hits a bump and moves up), the rod pulls on the suspension. Push rods push on the suspension when the wheel is in bump. Both work just as well for controlling wheel motion. It comes down to packaging which one you use.

    Thanks for that A Y! Good suspension tech reads.

    He fails even when he's not racing.

    Ha, saw that before. It befuddles me because bumpy surface or not, he was the only one (asfaik) to have that problem.

    I get the whole safety thing but why now? and why only during practice? *at least it's only during practice*
    Drivers have been going flat out through there...
    I wonder what the driver's take on this and if it has any impact in the opening laps of the race.

    From how I read that press release, it sounds like they cannot use DRS in Eau Rouge in the race, but during practice they can normally use DRS anywhere on the track. However, for safety, they are not allowing DRS during practice either in just that section.

    The concerns were raised last year: http://www.bbc.co.uk/sport/0/formula1/14615926

    It was never allowed through Eau Rouge during the race, though, so no impact on the opening laps. Personally, I'd prefer that they reduce the maximum angle of attack on the wings and free up the underbody then get rid of DRS. At least KERS can be used by the driver whenever he chooses and in defense of position if necessary.

    I dont understand why they make a big deal out of eau rouge anymore, its a flat corner. Tighten it so there is a lift, lets see some real bravery in that corner again.

    I also dont understand the point of DRS during anything but practice and race conditions. DRS is to facilitate passing, not improve quali lap times. It should be a moot point.
