Looks like McLaren are planning a big change to their car this year. Watching/listening to the Beeb coverage, looks like the Macca's are testing vision comparisons for the drivers, should they build a car with a much higher chassis.
In fact, the Friday sessions really are getting interesting with the level development the teams are researching for. Great stuff!
All of the Friday’s sessions have been revealing I have caught them all. It's 3:00 am and I’m looking forward to a cracking FP2
