I haven't played with R8 too much, but I thought there is something weird with speedometer. Now I drive with production cars just for fun and never use any HUD and there is indeed something wrong. Simbin have either very stange sense of humor or they are on weeds or something. On the left is texture and on the right real R8 speedo. See those number? But the real speedo is strange too. It's not linear from 140kph? Looks like the only solution would be to modified the texture for max speed of 280kph.
