G27

[[TC] Viper]

Shifter and wheel are much more robust on the G27 with smoother movements.
Also this is a great selling feature for me.

"Pedal Geometry Changes

Although SimHQ raved about the G25’s pedals in its 2006 review, the one area for improvement revolved around the geometry of the pedal faces. With all three in the same plane, it was very difficult to effectively execute heel-and-toe shifting. What was needed was to set the throttle pedal back a bit, so that a driver’s foot didn’t touch it until the brake was slightly depressed. Again, Logitech’s engineers were listening, and on the G27 the brake and clutch pedals moved forward with the help of a 13mm spacer block behind the pedal face, allowing for more natural and effective heel-and-toe braking."
