The news follows a season where the Ford versus Holden rivalry roared back to life, thanks in part to the Blue Oval’s official return with the new Mustang.
After eight years in the Tickford family, Mostert had been targeted by WAU not only for his driving skills, but his highly marketable personality.
Regardless of his status as one of the category’s most popular young stars, the 2014 Bathurst winner acknowledges he will lose some fans from the switch.
I’ve had an incredible chapter of my racing career with FPR/PRA/TIckford Racing, made life long friends through the journey which for me is the most rewarding part and I wish the team all the best and looking forward to the challenge of competing against you! #Mozzie55#VASCpic.twitter.com/goFZKCe4rq
“I have had a some awesome fans over the years racing with Tickford Racing,” said Mostert in a video posted on his own social media channels.
“I know that the Mozzie fans, I might lose a few along the way as there is a much bigger brand in the Ford oval camp that you guys support, but I just want to say a big thank you to you guys for supporting me over the years.
“Its been an up and down rollercoaster but for me the fans make our sport and we truly have some of the best fans around the world.
“Thank you so much, I’m looking forward to seeing you at the track even though you might not be going for me anymore.
“I just seriously want to say thank you for all your support."
