Yeah, they are rear calipers on the Porsche for a reason.... but I've never been a fan of mixing and matching bits when it comes to brakes. I'd rather buy a purpose made kit for the car, such as AP, Stasis or Revo. You'll get the power and the pedal won't change. Even the much praised MK7 PP with 340mm kit has a longer pedal, and that's OEM parts. I really can't be doing with soggy brake pedals!
