Remy, who scored on his debut against West Ham United yesterday, admitted that even the slightest of problems can affect his game.
"When I'm 100% I can do very good things, but when there's something not quite right in my head, something's bothering me, it becomes difficult," Remy told the Sunday People.
"My profile as a player is that when I've got a small problem, things become difficult.
"It might sound pretentious but the physios say that I'm like an F1 car. Whenever I've got a small problem, it's straight into the pits."
QPR beat off stiff competition from Newcastle United for Remy's signature.
