On a somewhat very wet track, front end pushed in corner if on braking. any suggestions on how to avoid this in the future?

A push under braking could be caused by a lot of things, but here are a few places to start..

More rear brake bias,
More crosswieght (pin the LR harder and the car will try to pivot around it under braking),
softer front or stiffer rear springs.

These are just starting points, there could be any number of things causing it. I'm guessing that you've probably taken crossweight out of it thinking it should loosen it up, and it will under accelleration but under braking it works the opposite, as I've detailed above. You may want to check your caster split across the front of the car also. If you haven't got at least 2.5 degrees more caster at the RF than the LF, that could cause it as well.

You also said that this happens on a "somewhat very wet track". If you mean it's ultra tacky, try going in the turn without brakes, just lift off the throttle. This will bring a car around pretty quickly. If it's wetter than ultra-tacky, it's not ready to race on. Tell your promoter to run more packing laps.

Hope it helps,

well, we arrived late due to work schedule. no practice. I thought the track could have been run in more but they were trying to get it in before rain. mods were first to race, then late models, streets, 4cyl. fried the ignition system last lap of heat race. car just seem to push but I half suspect is was just too sloppy and driver (me going into turn to fast) trying to pass another car and got tagged. but that's racin' I reckon. wished could have run the feature cause I really think that feature time the track was nice and tacky.
thanks for the advise.

Gnarly hit it on the head X. You can also put lighter shocks on the front and it will dive a little more and unload the rear a little more. I prefer adjusting cross, its easier to do, just add air to the RR or LF or take air away from the RF or LR. Just another way to do it. There are so many ways to unhook a car...just basically preference.
