F1 tuning guide

found a little tuning guide here this morning if anyone wanted to know how the tuning setups work

I could go on and on about the "tuning" in F1, but have come to learn a few basic things through being lucky enough to race with the worlds best F1 drivers:

a.  real life principals do not apply to many of the tuning parts in the game.
b.  the best tunes don't look all that different.
c.  never intermingle Forza4 and F1 2012 tuning philosophy.
d.  a fast an clean driver is far more valuable than a good tuner.
