I have never heard of that option avalilable on any roadcar before!
The Agera is equipped with the absolutely latest ABS technology and is based upon, a very lightweight and performance
oriented, racing ABS system. The system makes it possible for the ABS function to react to differently depending on
performance mode. Furthermore the ABS braking system operates on massive 392x36 mm and 380x34 mm ventilated
and drilled ceramic discs, for unparalleled braking performance and zero fade regardless of track or road condition."
