Mapes-VO spent all 4 days improving reliability and had the top two times over the 4 day session. Stealth GP became the first team to maximise their BHP and reliability according to the allowances allowed in the 2003 rules.

EIRE missed day 4 of the session ? a day marked for reliability testing ? this could cause them problems in their fight for Drivers and Constructors Championships as all their main rivals (SCUM, Mapes-VO, Phoenix F1) have better reliability.
