How do you win races in Racing Live?
To win races in Racing Live you have to get 5x the parts, and crew, of your level.
For example, if you're level 5 then you'll need 25 of each part, and 25 crew.

There's a variety of cars you can max out on, but I recommend the Clio and Evo combination; there's no upkeep for these cars.Own only one car with upkeepSkill points: the points in speed should be equal to your levelHandling: should be as much as possibleFuel: Enough for the top street job, one timeIntegrity: Don't spend any skill points in thisFocus: 10-15
These parts cancel each other out:
Stage I turbo kit, Stage II supercharger, and Stage III twin turbo.Dual exhaust and performance exhaust
Bulletproof windshield and lexan windows
Remember, you only want the advanced part, for example:
Stage III twin turboPerformance exhaustLexan windows

Hope this helps :)
