The primary reason to get the "wet" fluid out is that it lowers your brake fluid boiling temp from around 600 degrees down into the mid 400s. (track temps regularly are in the mid 500s)
Road and track crashed the 09 press 370 during track testing from boiling fluid (OEM DOT 3 fluid I believe)
The short answer: Use good DOT 4 fluid and FULLY bleed out your fluid to ensure its "dry" 2 bottles will get it done if your are perfect, so buy 3.
I bleed mine at least twice a year (during track season) and its very easy.

Good stuff

I've only heard of problems arising with the ABS when excessive pressure is used. My research indicates that you should never go over 15 psi on any car, and some cars can't handle that. I've power bled the Z's brakes numerous times at 10 psi maximum. The power bleeder is far quicker and easier by myself than if I have a buddy to help pump the brakes
