Actually, the red lipstick is to distinguish which assemblies are Kubica's from Petrov's.mith wrote:I think it might be there to distinguish new front wing from the old one (it's on the back and without that red line) as it's quite easy to mix it in the rush. BMW Sauber mixed wings in one of the last year's races.
Looks like the drivers will be running different wings in Bahrain..
