[FONT=Times][SIZE=7][COLOR=red][B]I Bought a 93 325is about 3 months ago and I'm looking to upgrade the brakes and rotors. I've been looking at Zimmerman cross drilled of brembo cross drilled but I have no idea which one is better. Any helpful info?

Cross drilled is alright, but look more into slotted rotors. Cross drilling rotors actually wears down the integrity of the metal thus causing cross drilled rotors to become prone to cracking. It has been proven that the vented and slotted rotors are also more efficient at cooling than plain cross drilled. Just my two pennies...I would go with Brembo none the less though...

I heard that too.... cracking around the actual drill holes.
Still, I'm sure Brembo disks are up to a fair amount of punishment whatever their design!

For the past 15 years, they've been making performance pads that exhibit nearly no outgassing, which is what cross-drilling aims to fix. Slots and holes both decrese surface area, and actually hurt braking, if outgassing isn't in the equation. If you're using shitty pads, they'll help. If you're using good quality pads, there is no reason or justification for going cross drilled today. You'd notice more of a difference using directionally vented rotors rather then radially vented ones, if anything. If you feel you MUST get something that looks fancy, go slotted. Cross drilled tend to develop cracks and eat up pads like a Rosie O'Donnel at a candy shop.
Read a bit more about it first, let me see if I can dig up a link or two for you...

so, what do u think are GOOD BREAK PADS??? pagid??
Worst thing you can do is get your pads from Autozoo or pepboys; stay away from shit like Raybestos, and other autostore over the counter junk. Basically, you really do get what you pay for. Daily driving, go for OEM. Best balance of quiet, clean and fast stops
If you don't mind noise, and meybe willing to shorten the life span of your rotors a bit to shave a few feet off, try the afore mentioned EBC, or any other "performance" pad (There are liuterally hundreds of them, google?)
