Simon McBeath's book is worth reading, especially if you're putting together your own package.

Thanks, bought the book, so now just need time to read it!
Sounds like the widest possible, so 70” is the go...
Any recommendations, GT predator around 800, any others people are running and recommend on a 3.8RS tailbase?

This is a very cool discussion, gentlemen. My track car is an early NA 944. With so little power, it forces me to focus on my driving. But now, you've got me thinking about some basic aero improvements to reduce drag.

Jack, you need to invest in some Kiel probes for your wing. :)

The 944's are better aero than a early 911, especially a wide body. A wide body early 911 has the aerodynamic efficiency of a small refrigerator...

In that case, I'll keep whipping the driver. :D
