Rumour has it that Fiat are no longer putting the M-jet wheels as we know them on the M-Jets any more, they have replaced them with the 1.4 wheels that come standard on the 1.4 Starjet sporting and 1.4 T-Jet sporting. The t-Jet can be remapped but due to it being a new(ish) engine the map has not been developed much and GSR/Red Dot are trying to improve the map. Correct me if i'm wrong peter.
