i removed my spare tire, trunk carpet, car jack and tools, trunk paneling, rear seats and hardware, antenna motor, rear tweeters , rear speakers and hardware, front carpet, sound material, passenger seat, door paneling and system 10, glove box, center console + around the shifter and e brake, under dash driver paneling, hatch paneling and small window panels.
i didnt remove the soundroof paneling since it will get hot and it will block some of it away. i was hoping to drop 100 lbs with all this gone in my GTS.
Next is to replace the glass in the hatch and rear windows with something lighter.
