Help to find the following books !!!

Hello everyone, I'm new to this forum. After an extensive search for some specific books, I've decided to turn to a forum to see if, with everyone's help, we can find them. The books are about competition mechanics; below are the titles and authors.

If anyone has them or could provide a download link, I would be very grateful.

The titles are: Suspension in Competition Cars (Orlando Ríos),

Aerodynamics of the Competition Car (Simon McBeath),

Competition Car Preparation (Simon McBeath),

and Preparing Production Engines for Competition (Stefano Gilleri).

Thanks in advance for your help!
