Reviews of OEM Audi brake caliper

I just put the audi 2 piston calipers and SS lines on the front of my 2.0. Also put ATE super blue in. Haven't done ther rear conversion or lines yet. What I have noticed is that the pedal goes further before it starts to clamp, but when it does..... its almost like driving a hummer, if any of you have you know what i mean. Any ideas on the reason for that change?

I only ask because Ive been running this set-up for 2 years now. And its a minimal change, if not the same, effort to push the pedal...But the car is alot more controlable when braking than it was with the G60 set-up. Personally I like it better than most high performance set-ups for braking and feel...but it could stand to lose a few hundred lbs from the calipers.
