Now i know that this seems ridiculous but the last couple of days ive been going out in my car as its nice weather, and whenever i go round a corner with a bit of speed the backend steps out and not just slides but its drifts. Then it snaps back round into place, im not lifting off while im going around the corner nor am i going at silly speeds. my cars lowered 60mm and it usually goes round these corners fine but for some reason its just gone a bit wrong lately. anyone got any idea what could be wrong with it?? my tires are all brand new by the way. an the tires pressure is fine shocks and springs seem of but not really sure how to check them!! anything else it could be?
