You just have to reduce the size of the first dimension (change it from 4 to 3)
like that

PHP код:

new Float:RacersRandomSpawns[3][3] = 
{ 
    {2630.0979,1824.9392,11.0234}, 
    {2630.3567,1716.6747,11.0234}, 
    {2597.3518,1897.6078,11.0312} 
}; 


You have to be accurate using two dimensional arrays,

if you feel the need to add more data into that array, just put it this way

PHP код:

new Float:RacersRandomSpawns[][] = 
{ 
    {2630.0979,1824.9392,11.0234}, 
    {2630.3567,1716.6747,11.0234}, 
    {2597.3518,1897.6078,11.0312} 
}; 


Don't bother defining a size of the array, and let the compiler calculate it instead
