380/lipo
Well yeah it would take more then just tires but mostly it would be a
softening of everything rather then a total redesign of the suspension. Softer tires, lighter springs, lighter oils, ect ect. With the smaller rear pod it would give more options for weight balance with what little weight there is.
Tire wear/tweak
Tom there has been a bit of a change in the thinking on tweak. Previously the tweak adjustment adjusted mainly for an imbalance in weight in the car. Lately drivers balance the car first so that tweak settings are then nuetral. As for tire wear I'm more along Tom's lines. Suspension should be adjusted for handling not tire wear. Tire wear can be an indicator of where suspension could be adjusted but not always. You will always have some imbalance in tire wear because there will always be 1 turn more to one side then the other. In other cases sometimes it is necessary to accept coning to get the handling characteristics you want out of the car.
