I got a quick question. I have heard that LX's are lighter than GT's but a big margin. Other's say that they are not. How much lighter are LX's versus the GT's and is it worth removing the GT's ground affects and replace them with LX one's just to lose a few pounds?

Thanks

My GT weighs 2700 and form personal experience the ground effects don't weigh that much.

What did you do to the car to get it to be under 3k pounds?

Well, I got my car weighed today. 3240 without me in it. This is without any smog,a/c, no front sway bar, no fog light bracket. I forgot to take out my spare tire and jack. I also had two turbines with BFG drag radial on them. So I am assuming that the tires and jack adds about 30 pounds. So I'll say 3210 without me, with me in the car, 3370.

Greygoose, how the heck did you get your GT to weigh in at 2700? Did you change your front seats? Take out the rear? Tubbed? Let me know what your trick is. I would love to take off just 300 extra pounds! That's 3/10th's right there alone.

The biggest differences in weight are between coupes and hatchbacks, not LX vs GT, and even then, it's not THAT much. A hatchback GT and a hatchback LX weigh almost exactly the same as long as the options are the same, and a fully-optioned coupe weighs exactly the same as a stripper hatchback.

You've removed more than that to get to that weight. I'm certain the rest of the removed items will eventually come to mind...like maybe you forgot to mention the stereo, speakers, a/c & heaterbox assembly under the dash, fiberglass seats, etc for instance?;)

Ok let me think

No door panels
No back seat
No radio
No speakers
Alum driveshaft
Fender liners
Fog lights
Fog light brackets
I think thats it

Ahhhhh! Now that's more like it! Have you removed the door reinforcements yet? 15lbs each from what I've read IMHO....

I have basically removed everything that you have except for the front bumper support (how much does that weigh?), fender liners (how much can these possibly weigh?). I have centerline wheels which are not that heavy. I have aluminum heads and driveshaft. What did you put in place of your backseats? I also have heard that they really don't weigh that much neither.

Thanks for your input/help.

And no calibration certificate on that scale. Ford's published weight figures for a 93 GT are 3144 and it's not markedly different from a 91. I don't see 444 lbs of weight savings on that list. Frankly I see maybe 50.

Yes it is quite hard to believe, but hey, you can't say it's not possible. I weighed my car today at a local truck weigh station, electronically done.

Are you high? The weekend I went was a week right after FFW at Silverdollar raceway.




The front bumper itself is almost 30lbs
The fog light assembly and everyting is an easy 20lbs. So their's your 50lbs

Coupes are lighter...

If you take a GT hatch and a LX hatch, with the same options/rims/etc, the difference is the ground effects. They weigh between 30-50lbs max (I've had them off before).

The coupe is lighter because it doesn't have the heavy 70lb hatch/window. In its place it has a light-weight trunk lid and rear window.

After owning a 87GT hatch, a 92LX hatch, and a 93 coupe, I truly believe that people make way too big a deal when it comes to those "dramatic" weight differences. My fully loaded 87GT T-5 car weighed the same as my fully loaded 92LX hatch AOD, 3250lbs. The tranny offset the weight of the ground effects...

You take any of these given factors, it still more often than not will come down to the driver in a race, rather than if you have ground effects, or a hatchback. Those are just excuses that inexperienced drivers make themselves feel better with...

I will admit, that you take a Fox vert, fully loaded with AC, and it will weight a few hundred pounds more than a no option, no AC, T5, fox coupe...

So where's the other 394 lbs? Your car does NOT weigh 2700 lbs.

FWIW I don't care if the scales are "electronic" or not, the problem is accuracy at the far ends of the scale's capability. It's the same reason if you want to find out how much your muffler weighs on a bathroom scale, you stand on the scale with the muffler and without the muffler and note the difference, which will be a different (and far more accurate) number than if you just put the muffler on the scale. Most people get their cars weighed on truckstop scales which are intended for vehicles weighing upwards of 100,000 lbs, putting a 3000 lb vehicle on the scale is like measuring a feather on a bathroom scale. Or they weigh them on portable scales that are subject to all kinds of things like leveling and particularly wind...I weighed my notch on one of those so-called "certified" "electronic" scales at an SCCA race and it came back 4,000 lbs. Riiiight.

There's just certain things that should trigger your BS meter and one of them is a 91 GT weighing 2700 lbs and it's still got all steel body, an iron block, etc etc etc. No damn way in hell that thing weighs 2700 lbs. I'd be shocked if it really came in under 2900.

I got an 88 Notchback LX that weighs 2750 without me inside and a 1/2 of gas. FULL stock smoke grey interior, no AC no smog, holley carbed 302, HCI

But ye 2700 defo achievable lol, can't imagine what my fox would weigh fully stripped

Oh I agree with you completely that it is in the driver as well. But weight reduction is huge as well. Power-to-Weight ratio. I was just curious what other ways can somebody take some weight off a car without doing drastic changes. Like I said above, I have done what most have already. A 2700 pound 5.0 is extremely light without it being tubbed.

Those are my .2 cents.

OK, so now, with FULL DISCLOSURE, you're getting closer to that being a realistic number, even though some of your weights look like aftermarket parts vendor hp estimates LOL.

Now the next question is WTF you're only running 12.67 with that motor in it at "2700 lbs".
 
#23 ·
That is a lot of weight reduction. This may sound dumb but, what is "Convo Pros?" I didn't know the back seat weighed that much.

BOOM!!!!!!!!! I even forgot to add the difference from the stock EFI intake and mass air to the lower and carb.

1st time out with this set up and couldn't get the launch down. First time on DR's I would either blow them off and bogg like mad. Also the carb hasn't been touched It wasn't running that great that day.

What the heck; I'm curious if this calculator works or not....;)
My (before) car=3,000lbs at the same certified truck scale I always use,(the DMV sent me there when I came in from the military with an "out of state vehicle")

Dog bone 12lbs(I measured 8lbs)
Front sway bar 20lbs(what I measured + the end links)
front bumper 30lbs(8lbs for bumper+10lbs for mounting brackets by my scale).
Complete a/c 40lbs(I never scaled:( )
Superlites on the nose only 20lbs(I never scaled)
Alum D/S 8lbs(sounds right)
Alum heads 20lbs(sounds about right)
electric fan 5lbs(versus fan & clutch)
aluminum rear bumper 23lbs(8lbs versus 30 for steel)

Equals -155 lbs

I scaled at a cert. truck scale at 2,850lbs & the track at 2,860lbs....

Seems like fairly close numbers to me....;)
