I'm confused about which part number is which for the BILSTEIN front shocks.
I was told that the w0133-1608545 is the regular shock and the w0133-1608647 is the heavy duty. The fast lane has them labeled as the opposite but the price for the heavy duty (545) is less than the 647. Anyone know which is which?
