An option to turn rumble off would be great (I couldn't seem to find an option for it on my ps3 menu, wipeout, or online. so im assuming it doesn't exist)
I just laid my dualshock3 to rest. The left trigger (my left airbrake) is a little loose, and thus, when it rumbles it clickityclacks like crazy and throws my whole feel off if I just touch it a little and stop it or if it vibrates against my hovering finger. I just came off an online SOL 2 with it and am now back on my sixaxis.
