XRAY - Model racing cars

I've been running my FK on carpet with Foam tires for a few months now and have found a very fast setup. However, I'm realizing that the car may be a little better. During transitions the car feels slightly 'nervous'... perhaps twitchy. Its most noticable on left to right or right to left transitions but I've also noticed the nervous feel when transtioning from off throttle to on throttle.

Any clues as to how to make the car less "twitchy"?
My setup is..
Front Tires - Parma Cyan / 58mm / Paragon on inside 1/4
Rear Tires - Parma Magentas / 58mm / Paragon Full
Camber (-2) degrees on all four wheels
Front Links - Lowest outer hole on shock tower, 3mm spacer under link on knuckle.
Rear links - Lowest outer hole on shock tower, 2mm spacer under link on rear upright.
Caster - 6 degrees
Kickup - 0 degrees (middle holes)
Antisquat - 0 degrees (middle holes)
Wheelbase - Longest
Ackerman - Inside holes on the servo saver and ackerman extention plates on the Knuckles.
Toe - 1 degree toe-out in Front / 2 degrees toe-in in rear
Front Shocks - 30wt Xray Oil / 1 hole open / Light Red Spring / Outer hole on shock tower
Rear Shocks - 30wt Xray Oil / 1 hole open / Purple Spring / 2nd outermost hole on shokc tower, inner hole on arm.
Front Swaybar - 2mm
Rear Swaybar - 1mm
Ride height - 4.5mm front and rear
Droop - 2mm front 4mm rear
Motor - 27T Stock
Gearing - 128 Spur 36 Pinion
Parma Alfa Body

Almost forgot to mention.

Battery placement has left side batteries moved forward 1 slot.

The toe settings i think as i am discovering have a massive effect try less toe out on the front my 0.5 and more on the back. Depends how twitchy it is 3 if its really bad 2.5 is more advised.

Shift the weight back a bit with the batteries too

Other things to try are heavier dampening.

If none of that helps, you might want to lean in the shocks 1 hole. The outer holes give less side traction, but faster response.
