Will,
The car is Laslo Antal's of Queensland Australia, he is a professional photographer and you can find more pictures on his website at
www.wildpantera.com.
The flares are glass fiber and George told me they are actually a set of original factory GT4 flares. Mr Antal is using a 14" wide wheel in the rear to fill them out and it certainly looks the part.
Just a small point to clarify, but the home page you mention is that of PI Motorsports, and although PIM do fund this web board, PI (the club, with our own ' Amiable Ambasador & Persona of all things Pantera', George Pence as Director) is actually a different entity. Yes confusing isn't it!
