And here is the code if you are using the Timetrials resource - the following goes in tracks.lua:
{
title = "Davis Quartz Rally",
isEnabled = true,
showWaypoints = false,
checkpointRadius = 24.0,
checkpointTransparency = 1.0,
mapBlipId = 315,
mapBlipColor = 5,
start = { x = 2597.69, y = 2724.73, z = 41.42, heading = 285.98, type = 5 },
checkpoints = {
{x = 2716.74, y = 2731.56, z = 40.21, heading = 289.38, type = 5},
{x = 2826.96, y = 2784.53, z = 56.99, heading = 254.05, type = 5},
{x = 3044.20, y = 2839.35, z = 78.92, heading = 22.37, type = 5},
{x = 3071.47, y = 2985.91, z = 91.32, heading = 9.4, type = 5},
{x = 2935.37, y = 2920.21, z = 88.32, heading = 132.83, type = 5},
{x = 2687.61, y = 2957.61, z = 35.85, heading = 108.75, type = 5},
{x = 2632.82, y = 2895.39, z = 35.9, heading = 275.38, type = 5},
{x = 2739.54, y = 2914.84, z = 35.68, heading = 214.01, type = 5},
{x = 2709.44, y = 2822.34, z = 39.40, heading = 107.76, type = 5},
{x = 2628.59, y = 2847.20, z = 36.26, heading = 96.02, type = 5},
{x = 2575.03, y = 2743.90, z = 42.09, heading = 214.18, type = 9}
}
},
