I finally switched to Driving Force Pro, which will finally let me drive the FBM properly. I have a good time, but still need to figure out how to drive the cars.

Anyways, I'm kind of clueless how to make it into 900 degree mode. How do I do that?

to switch between the two modes you hold down the Select + R3 buttons on wheel (bottom) and the click your right trigger thing at back.

try the settings in my sig. i find it easier to drive if i change my dfp's steering range in the profiler for each class rather than leaving it at 720.

I have another question. How can I bind a button on my wheel so I don't need to use the keyboard to cycle through all the menu (tire, suspension damange, brakes+suspension adjustment, fuel/tire pressure options)?

TIA

You could record a keystroke and assign it to the button you want. As in, first select the button in Profiler, select keystroke, new keystroke. Then record the keystrokes you want. Work out how far down the list the option you want it and then do the following:
Press record
Press F12
Press the down/up arrow as many times as it takes to get to the list item.

I haven't tried it myself; but it works in theory!

Main problem is that different cars have different amounts of options, I believe. Watch out for that!
