Spend a bunch of time at AXs and experiment
I would check your alignment first. Excessive F&R toe in will cause resistance to turn in. Stock settings are very good for a sometimes AX car.
You didn't mention your tires. Tall, limp sidewall tires are not condusive to rapid changes in direction....they ride nice, tho.
Tire pressure is black magic. First you have to know what pressure gives the most grip. Willy nilly changes in pressure are absurd. You have to experiment is a logical manner to find what effect these have. Changing pressures off the ideal for fine handling adjustments are OK for a given specific reason *after* you know that all else is well.
Thses are my opinions and they are mine
