What Are You Doing/Have You Done To Shed Weight?

Rims are a significant amount of weight and effect everything.
Caveats are:
Super light flex excessively and or fatigue under hard use.
Can lose the weight gains by using much larger tires.
(I've posted a table of tire and rim weights I've used over in the wheel sub forum)

Aluminum intake. Some pulleys, although that's pretty minor weight savings.
Slightly smaller battery. That's about 10 pounds off the nose.
Removed the aftermarket A/C. No extra sound deadner or insulation. Manual steering.
Mini-starter.
Tried the K-H brake booster and didn't like it. Not sure that would be a weight savings, but its gone.
Drums to front disk was probably a wash since the '67 came with the smaller drums.

Weight and weight placement effects braking, steering response, cornering, as well as acceleration. Its very under rated in the hot rodding circles, maybe because it doesn't drive magazine and product sales??
