For sale is a set of KLC 166 Whiteline Rear endlinks. I have had them on my car for the last month (~1k miles). Looking to get $90 for them. Link for fitment here.
I like the design of the Kartboy ones and thought they would perform better on the track(recently installed them) . These whiteline ones were the best ones the vendor had when I bought my sway bars. These do have a little more noise over the KartBoy ones, but they did very well on the street.
