The official wheel of Gran Turismo, the Logitech Driving Force GT is designed from the ground up to provide an exceptionally realistic Playstation3 racing experience. Its advanced forcefeedback technology recreates bumps, crashes and traction loss with jaw-dropping realism, while the 900- degree wheel rotation accurately replicates the steering dynamics of many real cars. A comfortable 33 cm (11 inch) rubber-overmould rim provides a slip-free grip;the 24-position real-time adjustment dial (a first on a force-feedback racing wheel) lets you fine-tune brake bias, traction control and other settings on the fly for unprecedented control over your car's performance characteristics;and the fullsize accelerator and brake pedals deliver instant response.
If you are looking for a wheel for GT5, this is the official wheel and the cheapest I could find. A good, cheaper alternative to the G25 and G27.
