Strut boots...
 

Hello, my car (92 300E) has 112k on it, and im upgrading to bilstein sports because the car has started to wallow around turns and rocks back and forth for 15 seconds after a car passes on the highway.... anyway, do you guys think I need new strut boots? I don't know their lifespan or what they are made of, but I know I didn't order any new ones when I ordered the struts.... Can you even tell with mileage? Or well a visual inspection be needed? And if so... what do I look for?
