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...
I need a rebuild a RB25 motor. Could you guys lay down which machine shop is ok in dealing in RB engine in things like reboring the liner & porting the head?
