I recently went back to stock suspension setup with all new struts and springs and stock endlinks. And I always hated the way the oem endlinks in the front sit slanted like this ... / \ So when bolting them up to the stock FSB, that bolt wants to sit fairly horizontal but the end link is at an angle, as a result it makes the bushing deform and bend. Adding a spacer will help but still has that bend to it and over time might cause that bushing to fail.
I tried the Whiteline solid front end links but the result was just the same as in the stock end links. So I was searching for available endlinks and came across a Whiteline endlink for Subarus. But in this case it was a rear adjustable endlink with one end using a urethane bushing and other end a pillow ball type end where the pillow ball end can be angled to see fit.
These rear endlinks are Whiteline KLC182
There is a slight mod to these to make them fit. From one of the pics down below..you can see there is a black bushing that fits inside the bottom bushing. That piece is too long and the I.D. of it too big. So I made my own stainless bushing to fit inside the urethane bushing and also drilled the proper I.D. to use the stock bolt size. Once pressed into the urethane bushing (easily can be done by hand) ..this end link bolted right up.
Once I adjusted the length and made sure nothing was hitting or binding...I tightened everything up and have driven it for 4 days now and feels more responsive compared to stock front end links and I haven't noticed any noises or harshness from these.
Here are some pictures of the end result and also the stainless bushing I made (silver colored) next to the black bushing.
