okay well i know what each is and i wondered a few different things...

First... is there any difference between say... Brembo Blanks and whatever brand my local auto parts warehouse stocks?
This is as far as quality... stopping power etc.

2nd... I know what slotted, cross drilled etc are and i wondered if there is really that big of a difference from one to the next and how much difference between them and blanks?

what do you all recommend?

finally, are there any basic brake upgrades for example changing my rotors from LS to 94+ GS-R for a bigger rotor diameter? what goes into this... just rotors and pads or do i need to upgrade my calipers as well.

Thanks for any help anybody can give me.
