I was going to say supercharger is your best option. Can I ask why if your dad has just bought it are you colour changing and adding after market body kits? Dimma in my day was for the 205 gti and honestly I thought they looked crap. As as said amg usually means big engine big torque. The only way to stand a chance is to charge it. Then when you are street racing you can kill yourself and any unlucky person who happens to be in the wrong place at the wrong time at a greater speed. Unless you want these mods for a track day which I doubt.
All this money. Buy an m5 if this post is real.
