I did a little experiment at Monza. On the main straight the Lotus hits 215 before I need to break. The McLaren is bouncing off the limiter at 221 well before the braking zone. Makes me think the TT cars are not equal. At Melbourne I struggled for an hour to better my time in the lotus. Swapped to the McLaren and beat it by 0.2s in only 2 laps.
Just had a few laps before work today. Seem to be loosing lots of time in the 3rd sector, as I'm gaining nearly 2 secs through 1&2 best time so far though 1.36.441
