On the 8th gen the weak link was not the stock endlink but the mounting point on the rear lower arm. The reinforcement brackets started being included because people were breaking their frame mounting points, not their endlinks.
If you have the $$ get the moog endlinks but if you just don't have it all at once, don't worry about it. Ive been running my stock endlinks for almost two years with the 22mm bar without issue. I have an 8th gen coupe.
That said, on the wifes sedan, she is getting the moogs cause her car is heavier and she drives like a beast.
