Power on steering

[jcb]

I am after a bit more power on steering out of my mid motor'd 22. Mid corner rotation on hair pins is fine as is entry steering, but it's tending to push and wash out on faster sweepers and chicanes. Its the first time I have run the car on dry astro having mainly raced on grass / dirt and a lot in the wet so I've nearly always been chasing rear end grip. The set-up I finished on is shown below:
Any suggestions welcome,

Front Suspension
Toe: Out 0.5'
Ride Height: wishbones level
Camber: -1'
Castor: 5'
Kick Angle: 25' - Brass
Oil: 40
Piston: 3 Hole 1.45mm tapered
Spring: blue
Spindle Type: kit
Shock Limiters: 2mm
Shock Location: 2-middle
Bump Steer: 1mm
Camber Link: 1 - 1mm washers on tower, 1mm washers on hub

Rear Suspension
Chassis Configuration: Mid
Toe: 4'
Anti Squat: 2.5'
Roll Center: HRC
Ride Height: Driveshafts Level
Camber: -1'
Wheel Base: Medium
Oil: 32.5w
Piston: 3 hole 1.55mm tapered
Spring: pink
Shock Limiters: 0mm
Camber Link: 2-2 (2mm under tower ball stud and 1mm under hub ballstud)
Shock Locations: 2-inside
Hex Width: +1.5mm

Tires: Schumacher Yellow mini spikes on rear and Schumacher Cut staggers on front (not the low profile ones)


My initial reaction is that I could reduce the anti-squat or maybe try the 10 degree front blocks and go back to the standard width rear hex's.
