lighter/faster rolling/less grippy tires.
beyond that...not much.
chasing weight is a losing game if suspension isn't dialed.
really need more info as to the specifics of the situation= what is missing?

again, don't have the specifics of your situation but testosterone replacement therapy, steroids, mild amphetamines can also bring the magic back(your particular needs may differ)
