You will need the 1.8 brackets as well.
No real difference on the street. In autocross or track you will notice a difference during hard driving/braking. The size difference in the brakes isnt that huge.

Fade is what it will help you on. If you don't track the car, and don't punish the brakes into fade submission, 1.8 aren't even necessary IMO. The pad is what you'll really notice.

What did you have before?
