have noticed of late that my 2002 bug wrx wagon really like to loose the front then step out badly on correction. tyres aren't new but well legal tracking is a little off but should i be looking for anything else.

really caught me out last night on a swooping long right dropping then going up hill steeply and the front understeered then bit and threw the back out. put foot down and gave some opposite but slid back out on opposite side on a near blind bend. changed pants

 

please give a complete list of suspension parts, setup and geometry spec. tyre pressures as well.
