If u have got the standard 296mm front rotors u might want to upgrade to the 324mm front rotor (since u are changing them anyhow), that kit about half way down , it uses caliper adapters on the normal calipers , i heard the same thing about drilled rotors
with the torque split controller it is worth noting that it turns the car into a full time 4wd u lose the attessa , ie where u have no power to the front wheels through the corner and power to the front as u leave the corner , just to give u something else to think about
