brake upgrade

[StatOmaN]

Im gonna get a vt brake upgrade, just wondering does changing to twin piston and changing the lines mess with the abs? is there a diff pressure?

I dont think it has any effect on abs...the sensors at the wheels will still tell the actuator to work when lockup is sensed and change pressures to suit.
