Its my first time playing GT5 and I have a t300rs. The problem is the weak force feedback. On tarmac the wheel rolls free with a very small vibration on kerbs. There's a way to increase the force feedback ?
I use the good ol Logitech GT Driving Force Pro that was designed for GT4 & GT5. In the option settings I can make it rock and roll right off a table when the settings are in the upper most positions. You can find one reasonable I'm sure on the Bay if you still continue to play regularly.
