Ive got a bilstein pss. My question is, does it matter between driver side and passenger side on FRONT SPRING ONLY? But when looking at the model, i noticed that the stamp on the springs for my front is the same on both sides.. pls correct if im wrong, i think it does not matter which side is which because they both have the same model on the front...pls let me know...im not sure if the driver side is supposed to be a little higher to compensate for driver...thanks much
