<<<<has your braking performance increased alot with this set up ???>>>>

Hard to give you an answer. I haven't had a chance to put these through repeated hard braking, my main objective is to cool down the rotors.......w/the dimple and sloted rotors
I'm looking to disapate heat..............The Zinc coating has prevented rust......for a nicer appearence.

I use ATE Super Blue Brake Fluid , $9.95 a can 1 Liter

Good Luck w/ your choice

 

backing up what Stan said, Brembo will not sell you the
drilled rotors if you tell them you are going to race with them.

The slots are for racing ...
The holes are for breaking ...

(I made a rhyme!!!)
