Before you do all that- what's your swaybar situation? If the car has no rear bar, first add a rear swaybar, & maybe upgrade the front bar to a larger size. There's probably a sport susp Corolla model that has this, if yours doesn't those would be excellent. The difference this made on my Neon years ago(went from std front bar, no rear, to ACR/RT OEM full front & rear setup), was wonderful.
