I've gotten a few books on performance driving techniques and the like. The thing is - to me - this is the type of situation that is best learnt by someone SHOWING it, rather than TELLING about it.
A friend of mine owns a race car (currently a Van Diemen Formula Ford). He is a few years older than me, but has been racing for the past 15 or so years. On numerous occasions, he's showed me techniques while riding in the passenger's seat. Many more times still, he has driven my Ferrari and showed me ways of driving it a little harder. I've driven his Formula Ford and I can appreciate that this isn't something you just pick up in one sitting, but takes years of practice.
Granted, this is my experience. I'm sure if you word your articles correctly and include many photos, it could shed some light on some of the lesser-known techniques of high-speed driving.
