What can be done to keep the car under me and not spin when I have to let off the gas to avoid trouble in front of me. Four bar car with 90-10, 5th and 6th coil. Car is good otherwise.
Thanks.

maybe try reducing wedge. try to keep the car straight and don't hit the brakes too hard.
most importantly though is try not to get off the throttle abruptly, the car will sort of drop down and unload, doing all sorts of weird stuff. i learned that the hard way.

Only running 90-120 lbs of bite depending on conditions. I know I'm getting off the gas too fast, maybe if I brake more while getting off the gas slower? The car seems to come around before I really get on the brake. I don't really want to change wedge, because I finally have the car good entering, through, and off. I seem to need the 90-10 to get the car to respond to the brakes. Any other ideas?

check all the basics first.
i have found sometimes that the right front brake may jam on, particularly if you have turned it off part way through a race when the temperature is up, and have never turned it back on. my problem didn't arrise until 2 weekends later.
other than those few things, i'm not too sure, i've never really had an ongoing problem like that.
hopefully sdhnc29 (steve hendren), go24 and 2nd2none can help you out on this some more.

The car drives great getting in through and off the corners, you just have trouble keeping it under you if a mishap takes place infront of you and you are trying to avoid it? Is this correct? If so:

1) Dont be behind cars who spin out infront of you

2) What LR shock package are you running? You can stiffen Comp. so the car wont slam down so hard.

3) Revert back to suggestion #1

How old or how long has it been since you've rebuilt your brake calipers? Like Rocket36 has said with the RF brake can also be rusted up pistons that are sticking.

Is the track dry/slick when this is going on?

Well, some rules are hard to live by. ie..2nd2none's rule #1!
Hopefully we'll get there someday! I'm happy to have a driveable car finally with the competition we have now!
I'm thinking more and more that maybe I should brake before getting off the gas so much. The car seems to start spinning before I even touch the brake. The brakes are not the problem- don't have any calipers dragging or slow to release. The track is dry slick. I did run out of 5 valve shocks for the LR, and last week had to run a 4 on the LR. Should I run a 6 or stay with the 4 until I get my 5's back?

this is very strange... 4bar cars generally turn to the right when you get off the gas.
