My problem is actually bottom teams. When I drive for one of the top teams and using custom setup it is great (on Legend). When driving HRT, they just seem to drive away no matter what the setup is. Even my teammate is pulling 1 second from me. I just can't get it... how can they drive an HRT so quick, faster through the corners (when I have 8-9 front wing) and quicker on the straight.
Have you tried Torro Rosso, FI etc?
