The seat bottom is basically null, a few lbs at most, but the seat back and cross bracing behind it are considerably heavy (around 35-40 lb) plus, as mentioned, without a rear seat, you are free to remove rear seatbelts, tether/anchor locations, and various other bolts and brackets. In total, you stand to lose a solid 50+ pounds from it all.

 

The fenders are aluminum as well. I learned this recently.

HAHAHAHHA (err no , too many carbs)

 

Diet? 10lbs ez

 

The exhaust idea would be nice but doesn't titanium brake or crack easy If something hits it? Example if you're on coils and hit a bump?

 

I think you are thinking about carbon fiber. I'm on coilovers set just below stock height. We got rough roads and i never had a issue with it breaking or cracking.

 

Titanium requires special equipment to weld, so it's possible if you got a real cheap titanium exhaust the welds might be crappy and break on you with rough driving.

 

Just go custom aluminum you can buy the pieces off the internet and have it welded by someone else just as light and waaaay less expensive.

 

Take a poop before you go racing.

 

I completely gutted mt 350z and regretted it. I saved weight but lost traction and it was loud as hell. Drop the basics (spare and jack, stuff in the trunck.) When you talk about serious parts removal from experience this time Im just going on a diet. Best thing is when I want to go back to my "stock" weight I can just eat more pizza.

 

The only weight savings on my car is the removal of the spare tire and jack.

I had a CF trunk but recently put the OEM trunk back on.
