How can I improve my lap times on f1 2010 PC version?

Hi guys, I'm using keyboard,auto brake off,traction control medium, abs off and I'm struggling to drive the f1 car....I'm a pretty good driver though, nailed Grid or Nfs series....but f1 is way different.The main problem is the cars spins horrible when taking agressive an apex....especially Monza and Monaco...for instance my Best time on Montreal is like 1.14 , and at Monza 1.22 .Playing in the career mode on EASY, I never won a race.....my best time was like 5th.......tried different car setups......but no succes...
