G27 setup for rfactor f1 2010 mode

[noe173]

hi
i am new to Rfactor and G27 which i started using very recently. I am playing F1 2010 mod.
what i need is some good setup for the G27?
For the G27 software you can create a rfactor profiler with have loads fo setting:
like wheel rotation, steering - Throttle - Brake deadzone & senstitivity.... Force freeback... etc
Apart there are also other setting in the game to set.
Any help for car to brake better, and be lessnwheel spin when pressing throttle? ... maybe i can shave some time from my best time...

Thanks for you help in advance
