lol so just say toe arms with a lockout kit. the lower spring perch also needs a lockout kit if you get the upper control arm so its not just 1 thing.

The ones I linked are the most likely to drift under hard cornering. While the uppers are also bushings, they are less prone to drift. No reason to do those until you install the lower and re-check your alignment after a few track days.

the ones you linked are toe arms and yes i agree, get the lockout kit for those so you dont lose your toe alignment. the upper cant drift. both the bolts and that arm are solid. theres nothing to move.

getting the upper arm moves the camber adjustment to that arm and it will now be adjustable. you 100% can have your camber also move and lose alignment as that eccentric bolt is located on the lower spring perch arm that inboard. buy purchasing the upper arm with lockout kit, you install the upper arm and remove the OEM lower spring perch bolt and lock that out.

you now have a locked out car and camber and toe will adjust via the new arms. theres 5 arms back there. you only need to replace 2 of them and replace the lower spring perch eccentric.
