Yes stock endlinks work, but they always seemed cheap to me. I'm leaving my stock endlinks on in the rear and upgrading my front ones to Rallitek's. They are the same as factory, just better materials. I'm also stock height still so it depends on if your lowered. I think you only need to put a rear endlink on if you've lowered your GT...not sure about that though, might want to research it. Personally I'd be replacing OEM endlinks with new F/R Rallitek's if I was lowered.
