My gamertag is "nedge 360". Turn10 have banned me from the Forza forums (and blocked me from twitter, no explanation for either) so if you need to contact me, do so via twitter @nedge2k

The calculations on this site are based on the 1.0.4 tuning guide by GTR CesarsWrath. I have modified them slightly in the following ways:

-Metric figures now calculated in the same way as imperial
-Aero load halved before adding to corner spring rate
-Stiffness modifier is now based on percentage (+/-10-20%)

Ride Height should be set as low as possible without the car or springs bottoming out. You'll feel the car bottoming out, for the springs, check the forza telemetry by pressing down on the d-pad and hitting right a few times.

Differentials should be set as follows:

5-20%  
RWD  85%
  5-30%
