Quickest way to win GTA V races
Good for those who can't be bothered to win races for performance upgrades.

There is a track called 'Lost and Found'. It is a relatively short track clocking in at 1min 20sec of completion. There are straight aways and tight corners.
The best features of this track are the bumpy roads. There are critical moments where you you must let go of the acceleration or you will start to slide (likely spin out).
You should be able to master the track after 4 races -- you will get a good feel of the quickest racing line.
Out of 20 races. I won 17. Two lost due to mistakes, one to another racer that knew the track as well as myself.
You should keep opponents to 3 or 2. The first couple of seconds are critical. Don't damage your car either.
