Toyota stock front endlinks are not siutable for coilovers (even TRD
) or anti roll bars/sway bars.
The back stock endlinks might fail because of a stiffer sway bar.
From my experience, and I don't drive on flat smooth paved roads most of the time. I had a Tein endlink bend slightly ( I have the pic let me dig it up) on my HA's. I also had both front endlinks go bad about 3 weeks after install on my SS-P's. This is with the stock sway bars driving around on public roads and no track use.
Hotchkis are suppose to be the best. I'm now using Hypermotive endlinks, but for the cost and supposed benefits of a beefier and more well made endlink, I would go for Hotchkis.
I think the cost of both front and back will be around the same for Hypermotives front and the Hotchkis are more superior.
