Does anyone know the weight of rear seats?

I'd definitely like to know too.

Or if anyone has manage to swap the front seats yet. I wonder how much trouble the airbag will give. Might have to pull a good 'ol subaru resistor trick

My understanding is the front seats are HEAVY.
I want to swap mine out, and turn them into office or living room chairs. See if I can get the power functions working even heh. Heated+cooled + 12 way power adjustable office chair.
 
Does anybody know the weight of the spare tyre with its wheel?
 
Hi guys. Used to work for a performance automotive manufacturer and was in several meetings where adding mass dampers (weights) was discussed. Consider this, not only does the NVH engineer need to convince the chief engineer and program management that spending extra money on these parts is worth it; but, they also need to convince the weight, the fuel economy, and the vehicle dynamics engineers that it is worth it as well. In order to convince them of this they need a massive amount of hard data. These mass dampers are there for a reason and should stay in place. Just because a customer doesn't notice them doing anything doesn't mean they are not doing anything. What if I told you that trained engineers are able to pick up on things most drivers cannot? Just because those drivers cannot detect them working does not mean that they are not working.

Additionally, remember that rotating mass is multiplied in terms of effective mass for acceleration. Moreover, unsprung mass is also multiplied. Mass savings at the wheels is probably 10-15% better to remove than elsewhere. Do keep in mind though that the larger the radius the more important inertia the mass adds. Reducing mass at the center of your brake rotor (by going 2 piece) doesn't play that big of a roll in reducing rotating inertia. It does still help with reducing unsprung mass.
 
______________________________
I'll add one more thing: while putting the widest tire that will fit on the car is a great way to increase grip, if mass reduction is the primary goal, just put on stickier tires. For example, you can have more or similar grip with fairly narrow Cup 2 tires as you can with the widest possible P4S rubber.

Bumper bar? Is ours steel? I hate to mess around with safety of the car but if g70 bar fits and pulls decent amount of weight off its worth considering.

That is the best i have right now. They are 18 inch. But this wheel comes in 19 inch size as well.
 
With 18 inch it is 225/45-18. For 19 i would guess it is 225/40-19, but not 100% sure

If you can live without spare tire, that is at least 30lbs.

Easy weight savings (Kia put unreasonably heavy wheels on this car)
After reading about people having issues with the stock brake pads, I decided to preemptively put in some z23 pads with under 300 miles on the car. I took this opportunity to weigh the passenger side rear wheel tire combo (61.4 LBS) and the drivers side front (58.6 LBS). This seemed kind of heavy so it got me thinking. The Michelin primacy tour A/S tires are not my favorite, in fact I feel they hamstring the AWD car compared to the 4S I have on my other 2 cars and offered on the Stringer in RWD.
The Stinger is my winter car, however I have a dedicated set of snow wheels and tires) so I can get away with a more aggressive tire for spring – fall.
I took a look at an “affordable” wheel tire package. I decided to go to 18” wheels for a little more sidewall, however similar weight loss can be achieved with 19’s.
I looked at the tried-and-true Einkei RPF1 in 18x9 with a 35mm offset weight: 17.3 LBS and in 18x8.5 with a 30mm offset weight: 18.3 LB (yes according to tire rack the narrower fronts are 1 lbs more).
Looking at a set of 4S tires that should work with the AWD system I went with 235/45/18, 23LBS and 265/40/18, 27 LBS
Weight savings: one rear wheel tire combo (17.3+27) =44.3 LBS
Stock combo: 61.4 LBS
Rear corner weight savings: 61.4-44.3 = 17.1LBS
One front wheel tire combo 18.3+23=41.3
Stock combo: 58.6 LBS
Front corner weight savings: 58.6-41.3=17.3
Total weight savings: 17.1+17.1+17.3+17.3=68.8LBS!
I think I will be ordering this soon
I am sorry for taking up so much room with the numbers but I didn’t believe just how much weight can be shaved!

Lighter hardware? My one concern is if some of the bolts replaced are grade 8.

Crazy they don't just tell you what the actual weight reduction is. Just weigh the kit, and subtract that from the stock hardware you have left after doing the replacement...

They say the kit is ~130 pieces, assuming half of those are washers, that's ~65 bolts.
GR5 Ti weighs 4.4 g/cm3, the heaviest steel alloy is 8.0 g/cm3.
I have some bolts on my desk, they average ~20g each.

65 steel bolts =~1.30kg, x(4.4/8)=0.715kg Ti bolts.
Savings= ROUGHLY 0.858kg, or 1.29lb

Probably why they don't flaunt the weight reduction...
