Hey everyone! Nick from ResoNix Sound Solutions here. I wanted to show a solution that I have for something that I see and hear a lot of 911 owners, especially GT models complain about: unwanted rattles and resonance. 911's, believe it or not, are probably the one car model that I get the most inquiries about regarding reducing unwanted rattles, resonance, and gravel noise. Maybe tied with Tesla Model 3/Y and Ford Broncos for the most inquiries, but, whatever.. The point is, this is a commonly asked about problem and I finally got my hands on a brand new GT3 Touring that I was able to document exactly how I would go about reducing unwanted rattles and resonance without taking away from the enjoyable sound of the engine and exhaust of this car at higher RPM's, and without adding too much weight.

We ended up using:
1 Full Box (40 square feet) of ResoNix CLD Squares Sound Deadener
(2) Sheets of ResoNix Fiber Mat 25 Sound Absorber
(3) Sheets of ResoNix Fiber Mat 45 Sound Absorber
1 Box of ResoNix Guardian Sound Absorber & Noise Barrier
1 Roll of ResoNix Butyl Rope Sound Deadener
1 Sheet of Resonix CCF Decoupler 3S Rattle Decoupler

These products were used in the doors, rear parcel shelf/quarter panel area, and the wheel wells. In total, we added approximately 40lbs and had a drastic difference before and after. On to the build log
