In a '11? I know there is a spare tire back there. What else is back there that can easily be removed if anything?

 

Well thats about all I saw, the few times Ive popped my trunk. But running without a spare is like asking for trouble. Simliar to most people who go without health insurance, call it ironman syndrome, eventually its gonna bite

*Unless were talking track here, and then yea you could, but that steel wheel, may actually help keep the rear planted*

 

my spare/jack was the first thing to go out of my 95, about 2 months after i bought it.. drove for 15 years never had a flat.. if i did.. o well that was AAA is for, and/or can of fix a flat

then all the sound deadening behind all the panels and under the carpet/seats lost about 100# of weight but HEARD EVERYTHING on the road..

 

Well on all GT's with Brembo pck, there are no spare tire to remove.

 

And......No spare in the V-6's.

 

I've had three flats out on the road in 23 years of driving. One was 200 miles from home and I had a spare with me and changed it, another was 12 miles from home, spare was with me and I changed it there, and the most recent was 10 miles from home, spare was at home in the garage, so I had my wife bring out another wheel/tire (not the spare), a cordless impact, and a real jack. The flat was changed in about 3 minutes, and I was on my way.

I have AAA+ with 100 miles of free towing, and will typically leave the spare tires at home for at least a couple of our cars unless I'm going on a trip of more than 50 or so miles from home. FWIW the spare tire, jack, wrench, and associated hardware out of my '08 weighed 40-45 lbs total IIRC.

 

On Kim Kardasian the junk in the trunk has gotta be over 40 lbs!

 

no spare here either. I think it was about 30 pounds for the spare and jack.

 

Don't know the weight, but the odd 18" spare tire wheel has a VERY unfortunate "CHINA" stamped on it!!

First the 6MT transmission, and now the spare wheel? What ELSE on my car was manufactured by Chinese children, Mr. Mulally?

 

But doesn't some weight help to keep them tires from spinning so much ? On a track well I understand, me I like knowing I have a spare/jack/ & small J.Daniels encase lol

 

I race a truck lol Im sure I can handle a well balanced car.

 

You had me at "junk in the trunk".

Less weight is ideal, but for off the line, if you have the weight it's better over the drive axle. Random note: According to the GVWR sticker my car can weigh a maximum of 4600 pounds with cargo/passengers and can carry 700 pounds in cargo/passengers, so based on that it weighs 3900 pounds. About as much as a Camaro, but that assumes this is relatively accurate (I doubt it is, though I expect my car to be heavier than most with these options, the EP especially).

The fix-a-flat kit with the Brembos/V6 weighs only 5 pounds if my scale is right, not including the Styrofoam case, but I figure that's not even worth the bother.

 

No, 3900 lbs isn't close at all for an accurate curb weight for your car. Should be a lot less, right around 3600 lbs based on the weights for other 2011 GT Mustangs I've seen so far.

 

My $.02, is that unless you're 1/4 miling or tracking your car, leave it intact.

Really, the 50 pounds tops that you're going to shed isn't going to make a snowball's difference for 99% of your driving. If your car weighs 3600 pounds and has 412hp the hp/weight ratio is .1144444... hp/lb. Drop 50 lbs, and you've got (412/3550=) .116 hp/lb, a 1.3% difference or 0.1s in a 1/4 mile.

 

I think you meant .01

 

You mean in the quarter mile?

All things being equal 1.3% difference in hp/wt ratio would translate into (12.8 stock time x 1.3%=.17s minus drivetrain losses) so about .1s
