Forward Bite

I read alot about "forward bite". Can someone explain to me what exactly it is and how to attain it if it's something I need to go fast?

Thanks,
Al

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.

Putting the power down..forward bite.

Finding the balance between forward bite and turning is key.

A little cross-weight may give you a little forward bite but to much
has a negative effect on speed.

Moving the left rear tire OUT will give you more forward bite at the cost
of less steering or turn-in.

Its the total package and is not just one thing.

Everyone has there own driving style on how they like there car to handle on the track.
I hope this helps..

It's Called Wedge. I Also Agree With What The Other Guys Here Say, It's A Fine Line. To Much Forward Bite Will Result In A Push Off Condition..

Don't worry some one will mention the infamous .010 shim soon. LOL

I guess if all this is accurate at some point a .010" shim would make a difference right?
If the forward bite is so critical would you want to keep adding shims / cross weight until the car began to push then back your adjustments off a little? Thanks for all the help guys.

PS If you are making these two adjustments would shims or cross weight be the best to try?

They are talking about running the shim under the t-plate. Some folks believe that a shim under the forward t-plate screw helps with speed up off the corner.

Speaking of t-plates, can you guys explain the differences between super soft, soft, medium t-plates?

In relation to trying to get forward bite, is a softer t-plate helping with forward bite, or taking forward bite away and allowing for more rear grip?

Hypothetically-will softer rear springs with thicker oil or vice versa yield more rear / forward bite.?

Also-would having a larger left rear than right provide better forward bite?

Alan a softer center spring helped me greatly at Easley with the center of the corner and getting off. I went to a green center spring (using 40wt. oil). The car immediately turned better and seemed to almost "jump" up off the corners.

Before, with the stronger gold spring, the car was digging really hard in the center and I was having to crank it quite a bit to get it to turn.

It will help a little but it will hurt your turn in worse. Stagger is mostly used to help free the car on exit, The larger the RR is as compaired to the LR will loosen the car on exit. Another example; I ran a B-3 buggy on dirt oval , I couldnt get it to turn comming off the corner under throttle without pushing like a truck so I put on a RR .140 larger than the LR and it fixed 75% of the problem.

Forward Byte...

Forward Byte is simple...it is the amount of grip, the car has traveling forward
Side Byte is the amount of byte the car has in YAW (CORNERING)

Not sure who posted the ? about t-plates but, softer t-plate equals more side byte which doesn't yeild forward byte

Stiffer t-plate will give you lots of forward byte but tighten the car up (TAKE SIDE BYTE AWAY)....it's very much a give and take thing...the more forward byte the car has generally the tighter it is...yes a free car is fast but if a free car spins the tires off the corner----it lacks forward byte---

Thanks for the info Robbie.

One other thing....

I see a lot of people here talking about the RF tire "gatoring". What is it and what causes it to happen? I assume it is a result of the car being really tight?

this is signs of a tight car on entry and in the center, Thats were the most force is put on the car or will let the RF slide across the surface.


Forward Drive, Is it always the rear of the car, I think if the fronts not Right u are chasing a loosing battle.
