Fortune Auto E Series (W211) (2002~2009) 510 Track Series Coilovers

When the Fortune Auto engineers designed the Generation 4 Series, they made it a priority to revise the jetting for more accurate damper control. The engineers also increased the adjustment range. Every click in the adjustment range now has a very profound effect on damping force and each click is very audible and distinct. We responded to our clients' comments regarding the lack of audible distinction in the clicking mechanism. Our desire is to constantly refine our products using the valuable feedback from our clients, so we have addressed this issue with our Generation 4 shocks.
