here is my collection... 

loaded sgti (NA engine) turtle at a sharp corner... suspected his car oversteers, bang the longkang, and flip his car over like this...



turbocharged wira understeered into the same corner, hit the railing....



thus, conclusion is wira tried to overtake sgti from the inside... but understeered, hit the sgti rear end... send the sgti flying backwards first into the ditch.... and the wira understeer into the barrier....
