sorry doogs probably should have mentioned that what I suggested is probably more for stiffer springs.
 
I run on mine 1mm total out front, max castor, neg 1 per side. rear 3mm total toe in, neg 1.5 per side. its quite nice on the street. I have 2.3kg front springs and 4.6kg rear springs with 18mm swaybars both front and back.
 
so to answer you question I run neg 1.5 on the rear instead of max because the body roll is not as severe with stiffer springs so the camber change on body roll is not as great.
 
I found tyres wore very very evenly all around. front end grip was fine. more just lost it due to super**** spec front tyres.
 
 
For track/weekend I would deffinitly up that front toe to 2mm total out and I wouldn't personally run more than neg 1.5 on my suspension setup. rear I would probably leave about 3mm in and would up the neg to 2/2.5 per side




Thanks for the input, good food for thought.
I fitted Kings all round to my car recently and it already had a set of 4-way adjustable shocks.

ohh you didn't. I am so sorry.  HAHA
 
King springs are absolutely horrible in these cars. each AW I have bought lately have all had 17" wheels and kings springs and the ride is absolutely atrocious. they bottom out, they bounce badly and the draft angle on the car is not right, kings make it sit lower in the rear in the 4AGE and the 4AZGE is alot worse due to the extra weight in the rear end. Plus they also aren't held captive when at full droop.
 
But this is all personal opinion. I cannot seem to drive the car fast around corners with king springs fitted, I always found I would bottom out and smack guards. I could go faster around corners with even the stock springs fitted
 
I think general consensus seems to be good off the shelf ones are Eibach or RSR. I could not afford these I got some custom made stuff, alot of dicking around taking them in and out like 3 times getting them reset, but happy with the result.

I recently replaced the Kings in my AW11 with APEX springs. Massive improvement and the car sits level now as well.

I have heard people's criticism of Kings before, but these turned up at a price I could not refuse. Coupled with the shocks the car currently has it has been a vast improvement over the original springs. My only complaint at the moment is the lack of rear roll stiffness due to not having a rear bar fitted.

I found the easiest way to battle understeer was to have the front ride height lower, raking the car to get more weight over the front end. I have standard swaybars, and used to have tokico illumina shocks and cusco springs 4k front and 6k rear. alignment was 2 toe out front .5 camber and 8 deg castor with a 20rca adjuster. rear was 1mm toe in total and 0 neg.
