I would go to running the servo flat when the bite gets on the higher side.the bump toe in should relieve some of the excess steering and mellow the car out on entry. Maybe going to 6 degrees of caster also. 40 wt. oil may help quite a bit also to create a little more resistance in the shock helping to keep the car from rolling as much. I try not to glue tires unless it is 100% necesary. I also run my tires at 1.7 rear and 1.625 front for higher bite and a nice radius on the edge. Let me know how it goes. Give me a buzz when you are at the track running and we will get it going the way you like bro
