dthe holes and slot were originally designed to release pressure and gases back in the day, however today the material our brake pads (i think. my buddys a track guy and brake/suspension guru so i dont actually remember exactally why they dont work to release gases, just lettin you know so i dont sound like a pompus *** :P) the slots and drills basically only allow a little heat to escape and really help in the rain. i have baers and theyre slotted and drilled and talk about a difference in stopping power! i drove a friends gt down the 1/4 mile and about **** my pants when it wouldnt stop!!

Slots and holes are for the coolness factor
only. Baer Decellerators would have been
my choice IMHO.
I would avoid eBay non-name-brand rotors.
They cause all sorts of problems.
You could have gone name-brand
for the same price you paid on eBay.
Did you properly break in the pads and rotors.
If you just put them on and went, thats
why they are squeeking.

I did what the instructions said to do.
drive at 35 mph and brake at 50 % to 5 mph without stopping 3 times.

Then drive at 45-50 mph and stop at 75 % strengh to 5 mph without coming to a stop 3 times.

It's not really a squeak. I swear it sounds like I have a sparrow at the front wheels chirping soflty while rolling at about 5 mph

Looks like there is a heavy chamfer on those holes.
Maybe thats it?
