I will chime in. I'm sure there are some hotshoes who know more than me.
Forward bite is the traction the car has coming off the corner. If you have good forward bite the car will look like it was shot out of a cannon when it comes off the corner. You definatly want it. How do you get it?? Thats the 64 dollar question.
If the car is free thru the turn that will help alot with forward bite coming off.
Depending on the track surface,(carpet, asphalt, 'crete) type of tires(caps, foams) will dictate what it takes to get it.
Keeping the left rear tire on the track coming off will also help in all applications.
IMHO forward bite is just as important as how well the car is turning into the corner.
Hope that answers some of your question.
