“I'm so excited to be getting back behind the wheel of a race car at Zandvoort,” said Brown.
“I have tested with the team in our McLaren a couple of times now and I'm so ready to head to Zandvoort to see what we can do.
“It will be nice to return to modern day racing, having focused on my historic racing for the last few years.”
Dean added: “I'm excited to be taking part in the GT4 event in Zandvoort, it's one of Europe's great venues.
“The GT4 European Series is also incredibly successful and they are attracting huge grids, so well done to everyone at SRO.
“It's been a long time since I last raced a current United Autosports car so I'm really looking forward to racing the McLaren GT4.
“Zak and I have only really competed in historic events over the last few years, but we have been pretty successful, managing quite a few podiums together over the last few years.”
Along with his roles with McLaren, United Autosports, and Walkinshaw Andretti United, Brown is an avid car collector, and has an extensive fleet that includes the Supercheap Auto Bathurst 1000 winning Holden Commodore driven by Garth Tander/Nick Percat.
