I want to order a Held suspension and I need to know a few things.

What is the track width of the Fiero and the track width of the Murcielago.

How much should the front and rear of the Fiero be dropped to achieve the correct ride height of the Murcielago?

I been going to websites that have conflicting information, I need exact accurate figures before I have a custom suspension made. I am thinking I am going to need 3 inches per side in the front and 4 inches per side in the rear, I have no clue about the ride height.
