We are running a 4-bar/J bar car and decided to make a few changes to the car for last night's race.

In the past, the car has been fast, but a little loose getting into the turn and no side/forward bite coming off the turn. (Partly due to the driver's right foot.)

We had the car on the scales the other night and we figured that we would experiment with adding more LR bite to see if we could make the car use the LR more off the corner.

I don't know all of the weights/spring rates, angles, etc...but we basically went from 75 lbs. LR Bite to 115 lbs.

What happened in practice was that the car was still a little loose in, but now when he got on the throttle, the car straigtened up and was a push-monster from the apex on. (He almost had to stop the car to get it to turn.)

In the feature, it was a little better once he learned to let the car drift around before getting back in the throttle.

We were thinking of compromising and backing the LR bite down to 95 lbs.

I read somewhere that when you add LR bite, it will make the car tight in, but should help with drive off the corner. We had the opposite results.

Any advice???

(PS-This is a fast 1/2 mile track with 1 tight turn and one sweeper...)

Unless you drive in straight and with alot of front brake, more lr bite will loosen entry.

Your results look to be pretty standard per adding LR bite. Looser in, tighter out.

You might try to add some rear steer with that much LR bite to help it come on out of the corner. Maybe try moving the LR lower bar up one hole.
