I use a Driving Force Pro and I am currently #1 in the West by about 1.8s. I actually like the wheel but only because I don't know any better. What I really have a problem with is the brake pedal and the braking in GT5 in general. It seems like if I barely tap the pedal it applies full brake pressure. I might as well bind the brakes to one of the face buttons. =( I am losing so much time due to my poor braking and I blame the Driving Force Pro!
I am not sure what you mean by that. How does pushing the pedal down allow me to calibrate it? I would definitely love to be able to use the full range of the pedal instead of the 10% that it takes to achieve full pressure like it is now.
I did the bungie pedal mod and its amazing! The pedal feels so much better now and I have lots more control over the pressure. I made a quick vid to show how easy it is to perform the mod.
I'm can't break 250 and I'm using sixaxis. Will be getting a G27 for Christmas so we'll see how much practice I can get on it to work my way into the top 128.
