Losing weight

[blinkwatt]

The first thing I would do is remove your battery and replace it with a Braille or other lightweight battery. They weigh 10-15 lbs depending on which one you get, that can save you 30 lbs or so.

How much are the Braille batteries? Do I need a custom mounting kit?

After that, weight savings gets quite expensive. Going to a single set of high-flow cats and headers can save another 25 lbs, and give you a few extra hp, but doing so can result in CEL error codes if not done correctly (I know this from experience).

Changing the cats is a no-go here in California on the non e-gas,the e-gas folks can get away with it.

The easiest weight saver would be to remove the plastic box, above the engine if your car has one, that should be 20+ lbs, then you could remove the speakers, floormats, passenger seat.

If I were to drop that kind of money I would buy at least headers,those will easily make my Boxster faster compared to GT3 seats for the price. I would be iffy about buying them anyways,too many people said they aren't comfortable.

I was in your position a while ago. I took out my seats and was going to take out the carpeting and center console. When I got them out I saw the carpet is under the shifter housing and E-brake, while ive taken them out before for my short shift, i didnt feel like it and left the carpet in. The is the carpet behind the seats, thats about 7 pounds, carpet above the engine, another 10, front and rear trunk carpet weighs like 1 pound each, not worth it if youve ever felt how light they are. The wood under the rear trunk carpet is an option though, a good 10-15 pounds there. Run center console-less, buy a light weight ebay wheel, new battery. Im buying GT3 seats next month hopefully, Ive finally saved enough, now im just waiting to save up back up cash so im not stretching myself. If you are adventurous, take out all your carpet and drive around. See if you like it.

Dude Jon did the car feel different when you removed the seat and such from the car?

i drove w no passenger seat, and engine covers no diff in speed, but i was almost deaf.
you need to loose a lot of weight off the car to notice any kind of diff

You are right. They are not very comfortable for daily driving. A lot of GT3 owners have removed them in favor of other seats so there are quite a few good nearly new ones around for cheap. They are light weight though.

2800lb / 201 hp = 13.9 lb/hp.

2700lb / 201 hp = 13.4 lb/hp

2600lb / 201 hp = 12.9 lb/hp

* Boxster S - lets say 2850lbs / 252hp = 11.3 lb/hp
* 2.7 non s - 2800/217 = 12.9 lb/hp

Thus, loosing 100lbs is like gaining 7.4 hp. Yes, you should notice this, but.. how exactly are you expecting to see the benefit? Fuel Mileage? Cornering? Acceleration? I imagine that unless you are in "ideal situations" you might never notice the difference.

I know others have a list of ways to save weight.. but even saving weight can get expensive...

Seats an easy way to loose weight.. your seats likely weigh 50lbs each. Lightweight race seats are about 20lb each (save 60-70lbs)

Mufflers - could save 30lbs here

Wheels and tires - could save 10lb/corner = 40 lbs

Remove all unnecesary trim pieces/radio/speaker

Lightweight battery -10-15lbs?

Spare and toolkit - 20lbs?

Do the base non-option OEM seats really weight 50lbs? Can someone confirm this for me?

I was just looking at different seats anyway

only weight 19lbs. That may be something to consider.
