On the 2011 GT: how can its weight be reduced by 150-200 pounds?

Lunatic

with it being a track car only or streetable.....?

Overboost

Order it with the least amount of power options possible (manual seats, no heated seats, no electronics pkg., etc.), pull the rear seats, spare/mobility kit, trunk carpeting. After that, look into going with a lighter wheel, which can shave off weight pretty dramatically. If you're not driving anyone around, pull the pass. seat too.

With a new exhaust you can probably save 10-15lbs, ditch the stock seats for a set of Cobra Misano seats



These save about 25lbs...

Lightweight wheels..this can save an easy 20-25lbs (you will feel this as it is rotational mass).

You can also go to a set of Girodisc rotors, these save 18lbs of rotational mass (see above)

You can also go to a light weight battery ala Braille, this can save an additional 25lbs as it is half the weight of the OEM battery, not to mention this weight is in the front of the car (although close to the firewall).

All in all there is about 108lbs of reduction, but 43lbs of it is rotational and this will make a big difference. Mean while the car is still very much a street car.

I know if you move to a 1 pc. driveshaft this can be an additional 30lbs saved..don't know if the 2011 has the 2 pc. driveshaft like the GT500.

Street car - no track..., unless things change.

If it's not going to be a track car then what's the great importance of a small weight reduction?

200 pounds in a street car won't make any real seat of the pants difference, nothing you could feel.

Lighter wheels and tires can easily take off 30+ lbs, a smaller lighter battery can take off 20+ lbs (the one I have in my Bullitt was 25 lbs less than stock), Exhaust can save 15+ lbs, an aluminum driveshaft can save 25+ lbs, lighter suspension components can take off 20+ lbs, running without a spare tire and jack (if your car has one) is worth around 30 lbs, lighter 2-piece brake rotors can save 15+ lbs. All of that adds up to 150+ lbs, and you'll still have the full interior in the car. If you want to remove all the sound deadener under the carpet, that should be worth another 20-30 lbs, but will increase NVH a little bit.

i disagree, you're telling me that you can't feel the difference in handling and "off the line" sprightliness when the fuel tank is dry compared to when it's full?

15 gals = 92 lbs

i can definitely feel less body roll in my 2003 GT when low on fuel
i can definitely feel the acceleration is more subdued with a full tank on the Jetta (less so in the Mustang)

im doing the same thing you are talking about.

1. buy an omega 920 dry cell light weight battery. it weighs 14lb vs 65lbs for the stocker.
2. buy a steeda sway bar support or a granitelli radiator support. steeda=13lb savings 25 lbs savings for the radiator support
3. remove the strut tower support
4. remove the rear end damper if it has one
5. aluminum drive shaft
6. all aluminum suspension components where available
7. aluminum flywheel
8. aftermarket lightweight exhaust
9. light weight bogart wheels AND lightweight tires
10. cloth seat, spoiler delete. no extra options.

those are the things im doing with mine when it gets here.

If I can reduce weight 150-200 pounds, then driving with a passenger only puts the car back to its stock weight, and I drive with a passenger quite often. By the way, 200 pounds off a 3610 pound car is a 0.055 (five and one-half percent) weight reduction.

assasinator

200lbs IS equal to .2 at the track and on autocross its worth more per lap.

everyone else top out at 12.6 @111 well the lighter car will top out at 12.4 @ 113. that matters to me.


every hp you add with bolt ons is magnified by lighter weight. and those nasty 2010 SS guys have a more difficult time winning. consider this:

THESE HP ARE ASSUMING BOLT-ONS ARE ON EVERY CAR.

4060 lb (with 200lb driver)SS with 500hp(460rwhp) = 8.12 lbs/hp
3860 lb (200lb driver)premium with 450hp(395rwhp)= 8.57 lbs/hp.....SS wins
3605 lb (200lb driver)base weight reduced 450hp(395rw)= 8.01 lbs/hp ...light weight base wins by a mile.


the SS needs 506hp. and if the light weight gets to 475hp with BOSS 302 intake and bigger cams, the ss needs 534hp (470rwhp) just to be equal.

there are not 470rwhp camaros EVERYWHERE out there. there are some, but not that many.

Remember, 43lbs of my weight reduction plan is rotational mass..you will definitely feel this. The car will feel much lighter on its feet.

Well, there is always the hole-saw weight reduction plan...

Ministang

65 lbs for the stock battery? Where did you get that weight? That is about double what a stock Mustang battery weighs. I weighed the stock battery in my '01 Bullitt when I put a lighter battery in a few weeks ago. The stock battery was 36 lbs, and the Odyssey PC545 dry cell battery I put in to replace it weighed 11 lbs. I have an Odyssey PC680 battery I'll be using in my '08 Mustang that weighs 14 lbs, I'll weigh the stock battery when it comes out, but there is no way the stock battery is nearly double the size/weight of the one in my Bullitt.

Adam

He is incorrect, the OEM battery does not weigh 65 lbs.

conv_stang

if you don't mind spending the money to get there. the aluminum suspension replacement parts listed above will not only lighten the car, but are far stronger and replace the weak and flimsy stock parts. Which will not only reduce weight, but will also allow the car to hook even better on the track. or handle the turns.
And the lighter wheels, brakes, aluminum driveshaft and even light weight fly wheel that reduce rotational mass will allow the car to accellerate even quicker. That allows you to have a stock appearing mustang with a full interior, ac stereo etc.

assasinator

hmmm looked it up. you are right. you win a cookie.odyssey pc535.

Ministang

Ummm, your post makes no sense. If you looked up the weight of the stock battery, tell us what it is. What kind of cookie? What about the Odyssey PC535?
