just to point out - any kind of electronic aids are banned in drifting, full stop.
you could invest millions of pounds on a "drift computer" but you couldnt programme it to work within the realms of chance, which is really what drifting is. The human brain might not be able to function as quickly on a mathmatical level, however, a computer cannot match reaction speed when it comes to feel.
I believe the drift box will give you GPS speed and slip angle, but then that only applies to your location on the planet and not the particular corner you might be going at... ie. drift box says 50* but the angle against the apex of the corner might be greater - backwards entry style...
besides all this, you have a cossie, you will fail at drifting anyway
