OK, I was wondering if anyone here has weighed the front passenger seat, the rear seat, spare tire, jack, etc. I am basically wondering how much weight I could take out of the car before dragging it with those basic items? What I'm looking for are actual weights.

 

Check out FC3S Pro, theres some part weights listed on there FC3S Pro

From personal exp. my NA S4 seats seemed to weigh about 30-35lbs each and the back seat weighed close to 25lbs. The spare tire i just took out and am guessing it weighs about 20-25lbs with the tire. The jack and tools dont weigh very much at all (aluminum/made in Germany )

 

Ooops, I didnt mean rear seat... lol. So it looks like by taking out the passenger seat, the spare, and the jack I would be shaving around 60 lbs. Also, I already have one of the rear mufflers missing, so that's another 5-10 lbs savings.. lol. I wonder how much an S5 16" rim weighs, the site doesnt mention the S5 rims I don't think..

 

Im not trying to be an ***, but do you own a scale?? Just pull the stuff out and weigh it.

 

that is what I was thinking, it'd take like 5 minutes.

 

The light weight jack and tools only came on the S4 cars. The S5 cars got the regular steel stuff as Mazda was trying to cut costs.
