1.) In single player make it to the group called Loose Cannon.
2.) ts the only checkpoint event in this group - Event 4.
3.) Pick your car (i tried the twins Skyline GT-R NISMO Z-tune first but i felt like it had to must grip since this is a curvy course. I retried it with the Carver's Viper GTSR has a little more drift than the Skyline)
4.) You have to beat it in 20.0 sec for the 5 primary lights. dont worry about fans or the fan gates just go back after u 5light the event.
5.) You CAN HIT LIGHT POLES and lightly slide into guardrails ( i did by mistake a few times. this shouldn't cause any damage at all.) just keep an eye out on your cars damage if u see it go from a bright green to a light green u've take damage and you've failed it.
6.) just keep racing till you beat it. try to grab the nitros and as many stopwatches as you can. I saw the stopwatches more useful than nitros due to the hills and curves
it might take you a few tries just keep with it and you'll get it. i thought it would be hard to get but i was wrong.
