Just weighed my base 10r80 GT Mustang S650

[Q6543]

For anyone that’s interested… full tank fyi.
That’s alot lighter than I expected, pleasantly surprised!

All this 4100 lb talk seems misplaced from the s550 crowd

They see Dark Horse weight, and assume the GT is the same.

We are faster and same weight as the S550. Sorry to the haters.

Nice! I would love to do this. Especially after a few weight saving mods.

 

[Q6543]

I could definitely get this car under 3500 lbs without much, slicks, skinny’s, brakes, battery, 1/4 tank.

Dang. Base GT is the right starting point if you want speed.

get the whipple and enjoy.

3740 isn’t light, even with a full tank, but it’s better than expected.

Thanks for sharing.

Keep in mind that is a truck scale calibrated to weigh rigs at 30-80k pounds. I am not sure I would trust that weight as the margin of error that low could be as much as 3-5%.

Agreed, I doubt it's calibrated for passenger cars. Ford lists these weights for the automatic-transmission (10R80) variants of the S650 Mustangs:

Model	Weight
Ecoboost Fastback	3588 lbs.
Ecoboost Convertible	3741 lbs.
GT Fastback	3832 lbs.
GT Convertible	4012 lbs.
Dark Horse Fastback	3993 lbs.

Ooof, no body shaming here...
I'm proud of my big booty V8 convertible coming in hot at a whopping 2 tons.

What all is done to the car to get it 90lb under the factory weight?

A lot of people do it with a truck and trailer, then remove the car from the trailer and weigh it again.
