Its the dealers and the manufacturer that call it that. If Toyota calls a camry an ES then that what it is. Unless we can't trust the manufacturers or the dealers, or all the information that can be found online that says its an M4 clone..

 

AND internet firearms experts.

 

My car is at 90k. I'm wondering the same question.

Should I go with the oem arms or get the Daizen kit?

 

I just replaced my upper and lower. The only problem I had was getting the Damm bolt out. But everything seems to be working fine. Don't pay 600 DIY

 

Both, new arms for the ball joints and Daizen for enjoyment
