Change the direction in which a character spawns?

Hey
Im making a mario kart-ish racing game and i got the characters to spawn just fine, except that they spawn in the wrong direction. So when they spawn i need to turn around for the lap system to work, and the stage is designed to work when driving a specific direction.
Any know how i can fix this?
The code is use is this

using UnityEngine;
using System.Collections;

public class CharacterSpawner : MonoBehaviour 
{
	public Transform player1Spawner;
	public GameObject playerPrefab;
	public Transform player1Camera;
	
	// Use this for initialization
	void Start () 
	{
		GameObject go=(GameObject)GameObject.Instantiate(playerPrefab,player1Spawner.position,player1Spawner.rotation);
		GameObject go2=(GameObject)GameObject.Instantiate(Resources.Load(PlayerPrefs.GetString("playername")),player1Spawner.position,player1Spawner.rotation);
		go2.transform.parent=go.transform;
		player1Camera.GetComponent<SmoothFollow>().target=go.transform;
	}
	
	// Update is called once per frame
	void Update () 
	{
	
	}
}

Use the desired direction instead of player1Spawner.rotation
