using the gear ratios of a US Carrera with a G50 and the stock 225 50 16 tire height the top speed should be in the neighborhood of 150mph (149-155) depending upon whether you hit 6200 in 5th or you can get closer to the rev limit. The euro cars have slightly taller gears, I think, so may top out between 153 and 158. For you to have been at 130 in 4th (not 5th) at only 5800 rpm's sounds like your speedo was reading a bit optimistically like most of them do.
