Hello, 
 
You can not exceed the maximum steering sensitivity. But you can increase the sensitivity by changing mouse dpi settings:
On your computer, open Control Panel, and select View by Small icons or View by Large icons. Click Mouse to open Mouse Properties.  Select the Pointer Options tab.                                                                                                                                      In the Motion section, drag the slide to select a pointer speed for your mouse.                                                   Uncheck the box next to Enhance pointer precision. This is optional. Pointer precision causes the mouse pointer to move different lengths depending on how fast you move your mouse, which is negative for gamers. So we recommend to disable it.                                              After selecting a properly pointer speed, click Apply and OK to save the settings.  
With all respect,
Gainer
