With interior out of the Ferrari I can fit a Hushmat acoustic/thermal liner. Invented to improve the audio response of vehicles with ‘large’ stereo systems, it works pretty well on older vehicles to remove rattles. Basically it’s self-adhesive rubber sheet with a reflective coating on it. It reduces vibrations inside the car, makes everything sound tighter and reduces heat. The 308 interior requires a total of 55 sq ft for the bullhead, floor and doors.
