If you are using the front anti-roll bar you may have to loosen it off. Take off small amounts at a time until the front stops pushing. If it is completely loose and still the front end pushes can you swap cars with me
Only joking, my car pushes at the front too now that the weather is changing and the grip level has increased significantly.
I like to run 1 deg of toe-in on the front wheels which would account for some of my push but I found that now that the grip is picking up I am having to run the front of the car a lot softer to compensate for the rear grip.
I run on foams so my options for changing set up where restricted more. I softened the front (something I hate doing). Try running a silver spring and work with the anti-roll bar to get a nice feel. If you still get push then try using a shore softer on the front tire.
My current set up for the twin solids is:
one thick spacer in front for caster
40shore foam tires
60wgt shock oil
front anti-roll bar at 45deg angle
37shore foam tires
40wgt shock oil
rear anti-roll bar at hard setting (as far back with the eye as possible)
floating rear body mount
I also run stock rear side pulley and alloy front side pulley
68% steering dialled in.
This is only reference as it suites my driving style but it may not be ideal for a different style. But it will give a good starting point.
