Select the Thunder Challenge or Lightning Challenge at the game
mode screen. Complete the various challenges to get new Thunder
Plates. The Plates are awarded randomly from game to game --
winning a certain track with a particular driver will not unlock
the same Plate between games.
Make sure the race is set on ten percent difficulty. Then, cause a
crash on lap four. If done correctly, there should be a caution.
Go into the pits, and ignore that fact if no one else also enters.
You will probably be last, but there will soon be another caution
and the leaders will come in. Stay out and do not pit. After the
stop, you should be in first or second place. You will run low on
gas, but you will not run out. Block and you will be able to win.
