Has any one upgraded to this set up? please let me know.

Baer part number 2261030

 

I do not have experiance with that setup, but you may want to look into the www.frozenrotors.com slotted rotors along with one of the upgraded pads that they offer. I have there stuff and cannot say enough about the improvement in braking that I have experianced for a fraction of the cost of the kit you are looking at.
