No, don't upgrade Nitro, Suspension or Exhaust. You should upgrade Top Speed to 5, that is, try to go to 5554-5252. Increasing Top Speed from 2 to 5 will give you +85 km/h. Ranking will be 1698 and it's a rather high rank for a top speed of 506 km/h but I think that at your current rank (1439) and speed (421 km/h with TK) your car will never win any race in MP.
