I removed the rear seats, brackets, seat belts. All the rear interior panels, scraped off the asphalt like soundproofing, removed the sound deadening pad from under the carpet. took the soundproofing off the firewall.
I put the front seats back in the car though, The soundproofing was 45lbs rear seat and interior panels were around 70lbs. I covered the bare metal with thin carpet using spray adhesive. It doesn't look that bad but makes the car drive way better.
- I have to admit I took the spare, jack & tools out (-28 lbs). I put them back in for highway trips. But local driving, meh.
- Now that the SG is dialed in, I was going to stop filling the tank up (actually, since I fill up so infrequently, I was going to syphon out what's remaining, down to about 1/4 tank) (-36 lbs). But I haven't done this yet because it's been raining for about a week.
- And I've been toying with the idea of taking out the passenger seat (-29 lbs)
Which would mean a grand total of... -93 lbs (Edit: = -5.1% of total vehicle weight)
Coyote: you're a crazy man. Is the 45 lbs of sound deadening you're talking about just the stuff on the floor under the carpet?! Front and rear?
Also, in my car anway, you'd be further off leaving the rear seat in (6 lbs cushion, 16 lbs backrest = 22 lbs) than the front seat @ 29. Plus gain an extra seat - important if you're concerned about your "PPW-s" rating (passengers per weight of seating).
