Why wouldn’t you?

Every pound of saving equals a better more direct driving experience. Isn’t that why you bought the car? That’s why you replace the wheels and brakes with lighter kits to reduce unsprung weight. The difference is night and day.

I agree with that.

Of course, many owners aren't going to remove interior upholstery pieces for lighter weight. For those of us going to the track, however, a weight savings of ~60# is well worth the effort.

Many of us could cut another 20# of weight by cutting back on beer, pizza, cookies. More work but more benefits! 😂

Something to consider. If you plan to have aftermarket bucket seats up front (the route I took) and pull the rear seats as well, you can't safely transport another human being in the car on the streets because of the default deactivation of the front passenger airbag systems once the original front passenger seat occupancy sensor mat is removed (US cars at least...). I ended up leaving the rear seats in for now because I know my toddler is going to insist on going for rides soon enough. It's also nice to have the rear seats for adults in case of an emergency.

One day, if and when it becomes a track-only car, I will be taking out the rear seats and adding some type of cage and more advanced harness system, but for now, it doesn't make sense for my needs when I can keep the rear seats and just use a Schroth Quick Fit harness at the track.

Didn't realize the seatbacks were so heavy; the bottom is so light it hardly makes sense to take it out if you aren't wanting to protect the upholstery.

And I know it is a little off topic here, but am I the only person imagining a nice custom fabricated auxiliary gas tank that fit where that rear seat used to be? I'm thinking a full-width 10-20 gallon unit would end up looking like you fabbed a flat floor back to the trunk.

Old post BUT with a US car will this throw any codes for the R seat airbags? I may do this to carry our 50LB dog on rare occasions and my road bike. I really dont use the back seats so why not, looks easy and I've meesed up my leather before when loading bulky items. Glad they have the folding seat back option but it's still a small opening in there.

Can see from the pic in the thread (post #10) there are no electrical connections for airbags. They are in the pillars and front seats.

My mountain bike fits just barely, but it's constrained by length from driver's back seat to trunk. Removing seats has no benefit in that case.
