Circa 2005 caster is the most amazing thing drifting community has come across of. It improves your grip, steering feel and make you steer super fast during counter. But that was 2005 bro, when angle mods are still unheard off. With the angle mods we have now days and the way car is setup caster is no longer needed. Ill elaborate more on the front suspension geometry on a different post in few days.
But here is what waiting for you if you still think caster is the way. Torn out bushings and no grip. so yeah.
