I know I know the six sounds great in a 914 but I would like to calm the noise a little inside the car.
Is it possible to fit 5mm thick sound deadening under the backpad? I already have the factory tarboard ? in place so not sure if theres room. |

I knew a guy with a 2.7 and webers maybe PMO's doubled up the glass and it made a difference . But as Nathan said make sure there is no vibration in the glass itself
