Does anyone know the exact weight difference between the 05-06 stang compared to the 07-09 stangs? I know that the 07+ stang have more steel to accomodate for the gt500 engine.

 

I heard about 50 lbs. of extra. Anything that makes the chassis more solid and more squeak free is good in my book especially if you plan on keeping it for many years to come like I plan to. Mine is noise free and makes that solid "thump thump" sound going over railroad crossings.

 

I think the anniversary emblems are the reason for the 09 gaining 50 lbs.

 

I was just looking at the 09's the other day and thought they were slightly on the larger side. I was trying to pursue a friend into a S197 purchase. I think I gave him the stang bug...haha

As for the weight gains in 07, does anyone know where the extra beefing was added. I remember reading something about Ford adding some extra spot welds throughout the car.

 

Straight from the Ford Sourcebooks...

GT Coupe Manual Trans:

• 2005-2006 = 3,356 lbs
• 2007-2008 = 3,483 lbs (a gain of 127 lbs per Ford)

GT Coupe Auto Trans:

• 2005-2006 = 3,540 lbs
• 2007-2008 = 3,532 lbs (a reduction of 8 lbs per Ford)

In 2005-2006, an automatic transmission was a 184 lb penalty over a manual transmission. In 2007-2008, an automatic transmission was only a 49 lb penalty over a manual transmission. This leads me to wonder if Ford did some dramatic lightening to the automatic tranmission itself in 2007 to offset some of the extra weight of that reinforcement?

I've weighed my '07 GT at the truck scales on I-5 nearby. They are rated to be accurate +/- 20 lbs. It weighed 3,480 lbs with just a 1/4 tank of gas, so with a full tank (12 more gallons at 7 lbs per gallon), my car topped off with fluids would be about 3,565 lbs. That's about right considering that 3,532 is for a base '07 GT automatic coupe, while mine is well optioned car with 18" wheels, comfort package (heavy dual power seats), shaker 500 stereo, etc.

 

That sounds about right, I took the delivery sheet for my 07 GT manual with the actual as-is weight. I compensated for a full tank of gas and the calculation came out to roughly 3450 lb.

 

I weighed mine (an '07 auto) at the track with 1/2 tank of gas and no spare or jack and it came in at 3692 lbs. I weigh 190lbs. so thats put the car at around 3500. I believe the floorpans welds are beefier along with possibly stiffer subframe. Looks like no need for subframe connectors for a street driver. Anyone else have any info?

 

Holy why are there so much weight gain in the 07+ manual stangs? How much does the shaker1000 subs weight?

 

The 07-up Stangs had some extra reinforcements to handle the 500 hp from the GT500 and to accept the 5.4L DOHC V8.

 

shaker 1000's were not standard in the 07'sd so it does not matter.

 

I know the 07 don't come standard with shaker1000s but I was just curious as to how much it weights.

 

I weighed my '08 premium package GT shortly after I got it (only options are spoiler delete and the 3.55 gears), and on my Longacre corner scales, it came to 3491 lbs with full fluids and gas tank, and no driver.

FWIW a spec sheet I have from Ford from back in 2005 shows the Shaker 1000 as adding 73 lbs to the weight of a Mustang and the Shaker 500 as adding 14.9 lbs.

 

That is probably about right. The two front 8" subs are not that heavy (along with the four single channel or dual two channel amps to drive them), so 15 lbs sounds about right.

When you add two 10" subs, the enclosure and four single or dual two channel amps to drive them, I can see where that would add an additional 50 lbs over the Shaker 500. I haven't pulled out any Shaker 1000 10" subs, but in generally, those things are HEAVY and that enclosure can't be light either.

 

What does the Ford sourcebook say for a 2005 GT premium coupe, with manual trans and shaker 500, along with stock 17" aluminum wheels ?

 

It doesn't. It only lists the weights of a base model before options. The closest it lists to your car is a basic 05 GT Coupe Manual (deluxe, not premium) with the standard 17" wheels at 3,356 lbs. However, keep in mind that in '05, the only difference from deluxe to premium is leather seats and the Shaker 500, which is a negligible difference (15-25 lbs?).

 

The pdf I have of the weight spec sheet from Ford for 2005 lists the 2005 Premium Coupe as having a shipping weight of 3375 lbs and a curb weight of 3506 lbs.

 

I took my car to the local truck stop to check the weight last Thursday. It's an 07 manual premium non IUP and no shaker 1000 with optional 17's, a 1/2 tank of gas and no driver: 3480 lbs.

 

WOW ! I wasn't expecting a curb weight of 3506, for a 2005 GT premium coupe. That seems really heavy for an 05, as Shawn had his 2007 GT premium coupe weighed, and it came in at 3480 lbs.

 

Curb weights are figured with a full tank of gas, and on a Mustang, a half tank of gas weighs approximately 50 lbs, so if Shawn's weight with half tank of gas was 3480 lbs, add another 50 lbs to reach what its true curb weight is, and it comes in at around 3530 lbs.

 

Well that would seem more like it. Gas is frickin heavy. Well I'm headed down to Tillmanspeed for my custom tune in a couple of hours so when I get back, out of curiosity, I may empty my trunk except for what she came from the factory with.(spare, blah-blah) And I'll top off the tank.. Then reweigh. Truthfully I was surprised, almost to disappointment at 3480 lbs because I like road hugging weight on my car. I love a big powerful car!
