FWIW I started a weight reduction thread here that shows how much the changes I made are worth:

I haven't updated it for my suspension changes, but since the parts were all one-for-one I'm assuming the difference is negligible.

Right but he said he already had a 1/4 tank so the most he could add is about 60 lbs with a full tank. No I don't typically run a full tank but I do start sessions at 3/4. The saddle tanks seem prone to going dry on one side when you're sloshing it side to side in a track environment so I don't want to risk a lean condition by running too low.

I never run with more then a 1/4 tank at the track.
I run mine 1/4 mile at a time, at this time I havent road raced mine and dont believe I ever will,( Cant afford the wear and tear for Road Coarses, Paint, Brakes tires etc etc)
Fords Official weight says 3632 curb, which is exactly what mine would have been with full tank.

Driveshaft im not to sure about yet, $700.00 is alot of money for something I might not get back results at track, (I didnt see any improvement from a OEM heavy shaft to FRPP Alum one on last car)

^ he's right, you'll feel the diff the first time you drive it, the alum DS weighs 17lbs and it's not only rotating mass, it's before the differential so it has to spin 3.73x faster that the wheels. expensive but worth it

The only weak point in this car is in the driveline,....its were they decided to cut costs to come in at a price point. The Tranny/shifter and drive shaft although adequate, it comes up short in quality and performance, the driveshaft although quiet and void of NVH,...it weighs a ton, is over engineered and limits top speed on the street Boss,...the shifter is just pure junk, the China made transmission seems to be hit or miss for most,....long term I think we will all be sorry. The only real BIG difference between our cars and the 302s/302r cars are these components (with exceptions made for pure track car stuff).... I decided to keep the MT82 ,...because of that the first thing I changed was the driveshaft,...followed closely by the MGW shifter,.....it has made a big difference in performance.

For reference, I weighed my '12 base GT (with no options) on my scales. The car was exactly as it comes from Ford (spare tire, jack, floor mats, etc) and had a FULL tank of gas. Total weight: 3608 lbs.

I had for many years a 1970 Boss 302. I added sub-frame connectors and built up a homemade Boss 362 cid Clevor engine, hence the sign-in, and even with the larger (351) engine block, crank, etc it actually weighed in at only 3330 lbs on DOT scales with a full tank of gas. It wore 16" cast aluminum wheels with 255/50-16 tires. I never weighed them to compare with steel rims. Without the subframe connectors and with the lighter 302 block and internals it would have been closer to 3250. They were not nearly as heavy as the newer models. One of these days maybe I'll see what my LS actually weighs.

the strut tower bar is probably 40 pound son its own. i couldn't believe how heavy it was on my 10, the only difference between the two is that the boss strut bar is curved. Also the factory mufflers weigh a ton. i would bet each of them are 40 pounds. one was heavier by the arm dyno than the flowmaster hush power muffs i swapped to.
how it compare to aftermarket bars?
