ground control set-up with 275 front and 325 rear springs give hardly any squat, but is stiff. i also have 275-40-17 front and 315-35-17 rear, which will give the car a stiff ride anyhow. i have heard of people removing the rear swaybar with springs over 275 to help with your goals.
definately move the front struts to the rear and install the mr2 front struts as suggested. koni's are too stiff, tokiko's seem to work out the best, kyb will have you utilizing their warranty as long as you don't mention the car is lowered.... and if your wondering, this car does not drift at all. which is just the way i set the car up for how i like to drive.
