After a decent run with Toyota, Comas spent the 2004/2005 seasons with Masahiro Hasemi's privateer Hasemi Sport team, running non-factory Nissan 350Zs in GT500, including inheriting the team's only win (co-driving with Toshihiro Kaneishi) thus far, on the evening of 18 December 2004 at the "All-Star 200" exhibition race on California Speedway's combined oval / road course after the unofficial winners were penalized 60 seconds on their finishing time for a pit window infraction. Unfortunately, the race was a non-points scoring event and as such does not count towards the drivers' or teams' official win record.
