I've got a G27 and a Sportif seat lol. Love it. Back to me banging on about the new physics. The cars handle totally different. The slightest change to the suspension setup makes a noticeable difference. Same with tyres. The drifting with a steering wheel was impossible on GT5. So much easier on GT. Rallying is awesome too, just make sure you have ASM turned off. Really, really enjoying it.
