Total improvement was ----------------------- nothing!!!!!!!
Nothing in 60', 330' or anywhere else.
Might be some help in a lightweight car with a low torque engine, I don't know, but no one I have talked to ever said they picked up anything except a lighter wallet.

That being said, reducing unsprung weight had to help suspension. With shocks and springs seeing that much less weight to help them work better in keeping the tire planted. May not show up on the ET Slip as HP to the wheels is increased only very slightly but car may have an easier time getting down a marginal track which could show up in win lights.
