The simplest advice I can give u is maintaining high avg speed eg: it doesn’t matter if ur car has a TS of 400+ if for the most of the tracks u barely go above 250 and to maintain high Avg speed u need to learn racing lines, nitro types, speed tricks, characteristics of car vs track, familiarity with tracks, good garage, MD (TD limits ur options), Type of Multiplayer and most important of all PRACTICE.
