bhai i dont mean to diss you or anything but there is no such thing as sports mehran
secondly you honestly cant improve performance of your mehran by putting on body kit and bumpers etc etc etc
mehran was meant to be a economy car but hey i am no one to advice you what to do .. hur aik ka dil huta hai and i aint gonna be in your way
you should get plugs, wires, intake etc to improve your performance and than go for the outer look
