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

It's kinda tough to remove weight from these older cars since they didn't come jam-packed with safety features, electronic gizmos and sound insulation like newer cars; the weight is all in "necessary" components like the mechanicals and the body itself. I've taken a similar approach with my Duster; it's been lightened with modern aluminum wheels, aluminum top end on the 360 and most of the interior trim has been missing since I got it. That weight reduction has been basically offset by swapping in a B-body 8 3/4" and welded-in 2"x3" steel box tube subframe connectors. Which is actually good in a way because it at least shifted the weight more towards the rear so in theory it has better weight distribution but I haven't actually confirmed that with scales. My car is a constant work-in-progress I do amateur road-race stuff with (time trials, open lapping days etc.) so handling is very high priority, right now more so than power it already has more than I can use on the small track I race at.

The car does have factory undercoating but I have no interest in trying to remove it (effort vs. reward ain't worth it to me lol). It's all at the bottom of the car and is evenly distributed over the whole underside anyway so it doesn't affect the center of gravity a whole lot, could be argued it's almost somewhat of a benefit.
