Default EBC red pad and EBC slotted and drilled rotors vibrating

Hey guys so my brakes been bugging me for long enough to post something.
I had ebc red pads all 4 installed on all 4 ebc rotors the ones that are slotted and also drilled (not fully drilled more like dimples) and since day they have been installed they have been bit noisy. Which I understand would be pad going over all the groves.

But the part that gets me they vibrate quiet a bit the faster the speed that u stopping from and more force used to brake the higher the vibration. It's very different from the warped rotors i had them before so I know how they feel. The brakes specially when they heat up they stop like a mofo but like I said they vibrate a lot. The mechanic checked the pads and rotors all looks good so it's been over 10k now. Would be that they were not bedded properly ? I'm not sure if they did overheat at the begining I think I did some hard quick stops and they had enough time to cool off. Any ideas ? Don't want to replace everything as I feel I just spend $ on it not long ago.
Thanks.

you are feeling the slots. this is normal for slotted rotors, don't like it? don't use slotted rotors. My DBA2000's do the same thing.

Can't say I've ever noticed any pulsing/vibrating from my slotted rotors. Are you sure it's the slots in your rotors causing this?

I don't notice any vibration on my Powerslots / Hawk HPS pads. Just a kind of "woomwoomwoom" sounds when braking hard, but no vibrations, even when braking hard enough to get ABS to kick in.

Funny, I have the same issue, vibrates with light braking, but not on hard stops. I have those lousy Green EBC pads on though. I will be switching to the summer wheels and we will see how bad it is. I'll check the pads and rotors at that time. Just changed the rotors and pads, 8K so it would suck to have to switch them.

My slotted rotors on my 240sx never wobbled or made a sound, but the slotted rotors (racingbrakes sotted rotors and AXXIS Ult. pads) on my wrx shake and vibrate all the time while braking at higher speeds esp.

Ya know I paid more attn to it today and it seems only to be from one side

drivers front

I'm doing a full swap here soon so I'll inspect all parts and submit any findings if i have them

I've dba slotted fronts + EBC Redstuff pads on my daily

Not that on my race car I have OE rotors + EBC with NO issues or vibrations

this is defo something I can feel.... and it does seem to be that something is out of sorts....

Honestly doesnt concern me as I'm swapping rotors/pads over in a few weeks anyway
