That's where this car shines. It starts at around 2750lbs. Many cars cant dream of that weight these days. Wheels, exhaust, spare tire + tools and (heavy) battery delete can get you down another 100 easily. I cant think of a downside of losing too much weight in a car

Wrong ... Blanket statements are never good.
From a purely physics perspective, weight loss on a car is good.
From a practical standpoint, weight loss is not as important as weight distribution, especially with modified suspension. If you go with a fuel cell and lighten the car by ~60lbs or more in the back of the car, ideally you'd want your suspension spring rate and dampening to match the changed weight distribution.
Your suspension should also provide a degree of squat/antisquat based on the weight... and this is all towards your ultimate goal.
So, to answer the original question:
Yes, lighter items are great for going faster, but there's a hidden drawback. In general, losing weight on unsprung parts yields benefits.
