Noob question...
Are new sway bar link assemblies (e.g. http://www.whiteline.com.au/product_detail4.php?part_number=KLC144 ) essential when upgrading the sway bars or are they just a "nice to have"?
Is there an incremental improvement if they are added at a later time?
In other words, if I just initially upgrade only the sway bar will there be a significant beneficial difference (and no downsides)?
