I am looking to get some new endlinks and bushing. My question is whats the differance between 19mm and 21 for the rears? Also for the front 30mm and 32mm?

 

The 21mm bar will add about 188% roll stiffness if I remember right, so there will be almost double the roll resistance that you had before in the rear. Be careful though, roll resistance in the rear can cause the backend to slide out very easily. You might want to stay with the stock rear bar, like I have. I would recommend a 35mm front bar though. HUGE difference over stock.

So 19mm in the rear and 30mm is close to stock?

 

Those are the stock sizes, yes.
