Wilwood/Strange 4 Piston Calipers soft feeling pedal

So I spent the day on Saturday working on the brakes for my brothers drag car. He installed all brand new Wilwood up front and Strange in the rear, 4 piston calipers with 4 bleeds on them. Also a new Wilwood M/C, which was recommended by Wilwood for a 4 disc set up.

We bench bled the M/C, then the brake system. No air what so ever coming out of the lines. Took the car for a drive down the road the car stops fine and it will lock the brakes if we push hard enough. With the pedal about half way down. He also tested the 2-step and it held the car @ 3500 rpm. However what throws us for a loop is we are both able to push the pedal right to the floor. It never gets that solid feeling. He called a race buddy that has the same set up and his car is the same way..

I guess Im just looking for opinions from people with a similar set up, to find out if your brake pedal feels or acts the same.
