How light can we make an S2K....now?
I was just wondering, with the aftermarket performance accessories already available, how light could we make an S2K?
Let's say that someone wanted to keep a certain level of luxury (like A/C, and full interior), but wanted to make the car as light as possible with what is available now.
The car weighs approx. 2,650 with a half tank of gas...
The wheels would go first, correct? At least 20lbs could be shaved there. The fat exhaust would be next, and the Amuse would save another 42.5 lbs. That's about 70 lbs easily shed right there! does anyone know what the Ti control arms weigh? The Mugen sway bar weighs less as well... What big items am I missing?
I was just wondering how much it would cost, and how much we could reasonably shed without too much effort or loss in comfort. I think we could get the car to 2,550 lbs...or less quite easily.
Now I'm wondering about the effect on performance a negative 100 lbs would give us... Maybe a 10th in 0-60? Maybe 3-10ths in the quarter? The handling would certainly improve...
Help me out here, is this a worthwhile endeavor for the money? How much weight could we save with just aftermarket performance accessories alone? Could we make a Type-R ourselves?

Let me tally this up...
Savings...
Wheels: 20lbs
Exhaust: 42.5lbs
Header: 10lbs
Spare: 20lbs
Brakes: 30lbs
Suspension: 20lbs?
142.5lbs...hmmm...
(and a 40K S2K...haha)

A Spoon or Mugen header will save you 10-12 lbs.
After that, you might think about lighter seats. I'll bet the stock Honda seats weigh in around 35-40 lbs easy (Honda Civic seats weigh about 30 lbs without leather). A good lightweight racing seat will weigh in around 15 lbs (and give you better support and lower you to make the stock roll hoop more effective). Another 30-40 lbs there for about $1000-$1500 if you do both seats.
Call it then a total of 120 lbs for the header/exhaust, wheels and seats. That would be equivalent to adding 11 hp to a stock 2700 lbs car (spare, jack, tools, etc. weigh closer to 40 lbs, which would be worth another effective 3 hp and get you near your 2650 weight). If you actually managed to gain 10 hp from the mods as well, you'd have a car that accelerated like a stock weight car with another 25-27 hp!

There are few things you can remove without incurring cost,
You can remove the steel bumper support which the tow hooks are built in. Those things weigh pretty hefty. I had to remove the rear one because Mugen SS2200 rear bumper and exaust cannot be installed unless it is removed. I am sure you can do the same with front.
For others I guess you need to spend money for swapping with lighter parts.
Somethings that I can immediately think is:
J's Racing sells lighter replacement windows made out of lexan(or plastic?)
Amuse Ti header 5-7lb
Lighter battery from Feel's, Spoons.
Spoon's lighter aluminum suspension goodies such as upper,lower control arms.
You can also try more adventrous mod like Spoon's lighter pistons, flywheel, ATS's carbon clutch system.
Kinda wish we can do things like in the video game where you just click and do it for you automatically for weight reduction.
Well in the distant future I am sure people will all do everything in virtual environment.
You may want to also watch out where you taking the weight off from. While reducing overall weight is good, taking off too much from rear portion may give you unpredictable handling problem.

[B]Sheding the spare and associated tools, installing light weight wheels, light weight calipers & rotors, aluminium shocks, CF racing seats and aluminium brackets, a Ti exhaust and lightweight exhaust manifold, a CF intake and a gel battery will leave your car 100kgs (220lbs) lighter (and your bank account substantially more so...).
Any lower than this and you'll need to start replacing body panels by CF.

Leave off the optional hardtop - 44 pounds
Don't forget to take out the tools, etc. - couple pounds
Diet - how low can you go
