[869] 11 June 2011 - Mercedes MGP W02 - revised rear suspension
 
In Montreal Mercedes are evaluating a revised rear suspension set-up. The pick-up point (red arrow) between the top wishbone and the upright is higher and further inboard than before, in order to give a lower roll centre and better camber change. The team ran a comparative test during Friday practice and, if the data compares well, they plan to run the revision in the next few races.
[870] 11 June 2011 - Ferrari 150° Italia - Montreal-spec brakes
 
Montreal is one of the hardest tracks on the calendar for brakes. All the teams have brought special ducts to improve cooling and have used more durable carbon discs. Ferrari have followed McLaren's solution and also cut back the aerodynamic drum around the brake. They ran something similar in Monaco (see inset), but here the disc (a Montreal-specific one made by Brembo at Ferrari's suggestion) is almost completely exposed (main image).
[871] 11 June 2011 - McLaren MP4-26 - Montreal-spec brakes
The Montreal circuit is so demanding on brakes that all of the teams bring more hard-wearing discs and special ducts to improve cooling. Although McLaren are using the same discs they used in Monaco, they feature very different, cross-shaped openings to better dissipate the huge amount of heat that is generated on the Canadian circuit.
[872] 12 June 2011 - Williams FW30 - low-downforce rear wing
Along with Renault, Williams were the only team in Montreal to test an extreme low-downforce rear wing on Friday, but then not use it for qualifying and the race. Their design had a spoon shape in the central section to increase downforce.
[873] 12 June 2011 - Renault R31 - low-downforce rear wing
Like Williams, Renault tested an extreme low-downforce rear wing on Friday in Montreal, but then opted not use it for qualifying and the race. Their heavily-sculpted design was an evolution of one tested but not raced in 2010.
