Default is this calculation correct?

okay i did some research and i found that the curb weight of my 94 civic ex coupe is 2,231lbs wet.

i want to find the weight of my car as it is now with me in it. here's my calculations

cf hood
before : 35 lbs
after : 13 lbs

spare tire
before : 20
after : 0

jack
before : 5
after : 0

floor mats
before : 10
after : 0

rear seats
before : 10
after : 0

now i also have other variables i need to factor in but i can't find the weight...

- gsr motor with 18g turbo

- completely no carpeting and sound deadening tar (maybe 15-20 lbs?)

- passenger and driver corbeau clubmans

- no driver side seat belt assembly (probably 10 lbs)

- no rear seat belts (probably 8ish lbs)

- no rear interior plastic pieces


if someone can help me find the weight i need to find, that'd be really helpful.

TIA

Why not just pull through a truck stop and get weighed, instead of guessing?

That I don't know.

You could also try a scrap metal yard - they typically have truck scales.

the heavy duty scales are often off by 100 or so lbs.

and i can't believe floor mats weight 10lbs.

I would imagine the ones that weigh many tens of thousands of pounds could be, but the scale at my local metal scrapyard accurately weighed me alone, so I trust it.

Not sure where you're getting your numbers but that seems VERY light for an EX. MSN lists the curb weight for a 94 EX coupe manual tranny as 2,443 lbs.
