Good driving books?

[Mr Flat Six]

Hey guys I'm pretty new to the world of sports cars. I've had bikes for almost 4 years and have read a lot of books that helped me along the way. My skills riding a bike are the way they are with the help of these books along with many miles of personal experience. I'd like to become a better driver and will be trying autocross and driver's ed in the near future(hopefully sometime this year). In the meantime, I was wondering if anyone had any books they'd recommend on driving and maybe the mechanics or physics as well. Especially if there is anything for mid engined cars such as our Porsche Boxsters. Basically a book like A Twist of the Wrist but for cars.
