TRC off... maybe u pressed a button or something something that switched your traction control off. If so, just press it again when ur done drifting like one guy said...
If VSC always on... dunno, maybe u screwed the Vehicle Stability Control and it needs checking...
Any of you use Works product before? I am thinking to get a set of cam pulley. Anyone can give some comments? If you do not want to post here, can PM me.
