Too much turbulence in the rear. Was actually thinking bout this a few days ago; a better, or rather, a REAL diffuser would make a huge difference by creating better airflow that would improve the pressure difference between the dead space behind the rear end and the air flowing towards the rear. M Performance spoiler sufficient?

Mud flaps would also help, maybe someone could design sporty ones
