Here, you are looking at Superpro HD Rear Endlinks for your WRX, STI, or BRZ. 

Up until now most of the rear end links available for this application have either been spongy double urethane endlinks that didn't perform very well or overly complex adjustable length ball links that often failed, were difficult to install, and often had problems with noise.

Super Pro has solved these issues by designing a fixed-length hybrid urethane/ball link endlink. These end links will fit well with any OEM or aftermarket swaybar. They will also cope with the stress of a stiff 24mm sway bar without failing like some other designs do. If you want high-quality end links that will perform properly and not make noise these are by far the best option available.
