Sauber : Push-rod(because they use same engine and gearbox)
Renault Lotus GP : Pull-rod
Redbull : possibly Pull-rod?
Team Lotus : possibly Pull-rod? or more?(Gascoyne is very proud of their suspensions)
Mercedes, Force India, Mclaren, etc : possibly Push-rod?
Interesting. R31 has pull-rod suspension like last season’s Redbull. I don’t know actual benefit of each suspension configuration. All I know is pull-rod has aerodynamical benefit and push-rod is more flexible(for setting) but I’m not sure. Is it correct? What do you think about team’s suspension choice after Redbull dominant season?
I don’t have an indepth knowledge, but I do a little about Red Bull’s system. They used rear pull-rod in both 2009 and 2010. This partly why in 2009, although Red Bull didn’t have a double diffuser to start with, they were able to improve dramatically (with respect to Brawn) in the second half of the season.
Rear pull-rods allow a greater degree of flexibility when it comes to aerodynamics, particularly the diffuser.
McLaren traditionally (for the last few years) use a much firmer suspension than, say, Red Bull or Ferrari. They’ve used push-rods for the last two seasons (at least), so I’d guess they’d stick to it again for 2011.
Agree with Ichtyes. From what ive heard the pull rod suspension helps you lower your suspension closer to the ground and lowers the centre of gravity. The pull rod however, doesn’t work well with very high nosed cars.. so if Red Bull adopt the pull rod system expect their nose to be similar to the one they were running last year (even similar to the Lotus Renault’s). Ferrari has a push rod system which is a little more flexible and configurable and is more apt for a high nose car, as they seem to be running this year
