B4 hooking on carpet

[stuey]

Hi, I am having a problem with my B4 hooking on a small high grip carpet track. It looks like the front is rolling too much, and the inside rear wheel is lifting up leading to a hook into corners. I am using half worn yellow minipins with the following setup. I got to this after going from 35 to 45wt oil on the front.
Front: 45wt
Piston 2 Blue spring
Shock inner on tower outer wishbone Link 1A, 1 washer under balljoint
30 deg caster blocks
Rear: 30wt
Piston 1 Silver spring 1 washer inside
Shock inner on tower outer wishbone Link 1B, 1 washer under balljoint
Short wheelbase 1 deg anti squat, 35g lead in rear of car on NiMh cells
Cells split in middle position.
It did improve slightly after going up on the front oil, but I think either I need a geometry change or soften the rear roll to make it more even with the front.
Thanks for any advice
