The factory does not get involved with racing sports and GT cars but supports privateer teams that race them. They did this first with the 360GT where the factory official contractor Michelotto build the 360GTs. Michelotto also build the 360 Challenge cars for the one-make series. And now they will build the 575GTC (I think)
This year's successful 550GTs were built by British Pro Drive, a company owned by BAR principal David Richards. Another French company (I can't remember the name) also build the 550GT and raced them in 2002.
The factory is now forcussing on racing Maserati in the FIA-GTS and have employed Jean Jacques His, formerly Renault F1 engine chief to head the engine development of Maserati. I don't think Maserati will race against Ferrari because they are in different classes. 2004 will be very exciting, especially when Lamborghini enter the frey as wel.
