Why do you want 300rwkw? If it's just so you can say "I've got 300rwkws" you could always throw it on a hub dyno in 3rd gear Should go close to 300rwkw.
I lost my license through accumilation of demerit points (Speeding offences) and then it's snowballed from there because I have just kept driving. 1xDriving suspended, 1xdriving cancelled, 2xdriving disqualified.
