Hi Lads. I have a 2001 classic wrx impreza wagon GF8 (Irish car). I just found out that one of the rear shocks is knackered. I have the choice of replacing both rear shocks or taking the opportunity to upgrade all shocks. The car is standard and only used for normal road use. I'm not interested in stiffening up or lowering the car. Any thoughts or experience in this area would be appreciated. Cheers.
