Slip Angle :
The difference between the direction a tire is traveling and the direction it is pointing
Oversteer :
A cornering condition where rear tires operate at a greater slip angle than the front tires; the tendency of a car to turn more sharply than the driver intends while negotiating a turn.
Understeer:
A cornering situation where the front tires generate more sip angle than the rear tires; the tendency of a car to turn less sharply than the driver intends and compensated for by the addition of more steering input.
Double Clutching:
When shifting, rather than go straight to the next gear, the shifter stops in the neutral position, release the clutch, press the clutch change gears.
Syncros eliminate the "need" to do this. Some race trannys dont have syncros making this necessary. Also some of our work trucks have syncros that are worn out, and this makes it much easier to shift. Downshifting usually requires a tap on the gas though.
Fore-and-Aft Weight Transfer:
A load factor where weight is transferred from the front tires to the rear tires during acceleration and from the rear to the front tires during braking.
Most of this came from an info packet that came with some new tires I bought a while back. Hope it helps.
