What did you do to your 996TT today?

Brakes are up in the air. Not an S so, PCCB Brakes are too expensive for me. Any suggestions on lighter than stock brakes? I want to keep stock size or at least be able to keep my 18s for my wheels. May replace the hood with carbon fiber and a fixed wing since my hydraulics are shot, too. Debating on the seats as no one really rides with me.
Question.... to take the passenger seat out, anything special to do? Special procedure for anything electric due to airbto or any thing else. Just unbolt and unplug or more to it?

How are you liking the rennkit for the wing? Debating that as I don't want the stock hydraulics as they will keep messing up over time.

I am looking to replace some stuff on my 04 turbo. I would like to upgrade to titanium and aluminum bolts where feasible for minor weight savings. Has anyone done this and, without too much fuss, what opinions do you have? I understand some of the metallurgy issues and looking for opinions on that as well. Titanium is very strong with the right grade used and around 40 percent lighter.
I am not doing this all at once as I don't drive the car often. Aluminum is 60 percent lighter than steel but not going to use where structural integrity is a factor. Just looking to build as I go.
I have a convertible so, about a 200 lb handicap to start. currently put in 18 lb antigravity battery, Titanium exhaust with cats, light weight flywheel and clutch setup around 20 lbs., and back seat removal as well as nothing in the frunk. Lastly, put on HREs all around for lighter wheels and tires and Titanium lug bolts. Probably around 100 to 150 lbs lighter than it was stock. Does have a tune and turbos with supporting mods with around 550 at the wheels.
Thanks for future comments and opinions.

Yes, everything is gone in the front. Eventually, will replace most bolts on the car including trans bolts and bolts on motor where applicable so, will take time and money. Same for suspension and bolts that hold on panels. Once completed, I would guess around 50 lbs saved.
Talked to 2 guys who raced mx3s and said they pulled about 150 to 200 lbs of bolts out of those cars to race in the 500 dollar car races. Won't replace every single one but, no rust with aluminum and titanium and keep garaged and live just west of Atlanta so, no salt and only seen rain a few times since I bought the car in 2018.

I have to ask....why??? You're going to be wasting a ton of time and money and causing potential headaches for a few saved lbs. On a cabrio. What are you trying to accomplish?
I have also done all the basic weight shedding stuff - lightweight seats, steering wheel, 18lb HREs, exhaust, frunk empty, fiberglass/carbon decklid/wing, clutch, rear seat and belts, no rear fan, etc. Granted I have added a half cage. And my car still weighs 3300lbs. You really have to invest some money and time into ripping out the interior and replacing body panels with carbon to get below 3000lbs, which then transforms it into a track only car.
Those mazda guys probably just removed a bunch of stuff and threw it away, not replaced it with titanium bolts.
To answer your brake question, you could get 2-piece rotors ala Girodisc which will shed a little bit of weight.
And your seat question - yes just remove the seat. Make sure either your battery is unplugged or you don't touch the ignition while you're messing with the seat plugs.

Similar picture on the rx8 pages, they showed weight loss of a sentra or something like it and showed the stages. It ended up like the Porsche in the picture and did 0 to 60 in 5.8 and loss around 1000 lbs with barely a shell and motor.

I thought the hood was aluminum but read it weighs about 40 lbs.
I have the taller 1 thru 5 gears as I had to rebuild my transmission. It didn't want to go into 3rd shifting from higher rpms. One or more of the previous 6 owners didn't seem to know how to shift correctly. My old 06 rx8 had 150k plus miles and bought new and the transmission in it shifted excellent when I sold it. The only thing I don't like is having a nearly 2 ton car with light weight clutch and 6 puck with a 3.15 first gear. Once it is going, it is very fun though.
2 more questions. Any possible way to get the clutch to start catching closer to the floor? Also, should I do the switch to the gt2 or gt3 style clutch actuation? Can't remember which it was.
Again, thanks for the input. This is my first 911 turbo. This is my first Porsche period. I am looking for knowledge and weighing what is worth doing and not as well as the why. I know that everyone has opinions and a reason why. I am no different. I am customizing mine like others do. Sound doesn't bother me as I have 3rd, 4th, and 5th straight cut gears. 6th is normal at .75.
I like Mazda and Porsche. 2 winning brands in Motorsports. Porsche more so... there is no substitute. I will have more questions in the near future, too.
Thanks again for all the input. I live west of Atlanta in Carrollton. Hope to meet some of you in the near future. I love sports cars in general especially Porsche 911. Something about having the engine in the back always intrigued me.

I would think the buckle would need to slip through that hole to secure the driver/passenger...
