I was testing something diff so i went with the DBA rotors. Ran them for about 30k and never did any track days or mtn runs. Been working too much . Any way i went to change my pads and i had the rotors tested to see if they were still good. Being that they are slotted you cant realy turn them. Got the numbers back and one was right on the threshold and the other was way out of spec. So i pulled them off and went back to the cross drilled zimmerman (sp?) .

Just a little FYI if your looking at the DBA rotors.

 

hmmm thats not good.

I have the DBA slotted rotors, probably 15k miles so far and havent noticed any problems. Iv allways heard good things about them, how were they out of spec? Worn too much or warped whats the deal?

I just want mine to last untill i get a BBK

 

mine were warped out of spec not worn down bad at all. I was realy excited to have them on the care, but not now. like i said i never even did any hard breaking on them either. leaves me a little skeptical on them.....

 

ya thats strange. The OEM brakes have a bad reputation for warping, it is a kinda heavy car afterall. But iv never heard bad things about the DBA's before and i know a bunch of people over on AZ run them. They come highly reccomended as the one of the top aftermarket rotors in every aspect except price. I wonder if its another part of your braking system that could be causing uneven stress on them?

Iv done plenty of hard braking from over 120MPH too, i dont feel any vibration like theyre warped. Like i said ill check mine out in a couple weeks when i start taking my car apart

 

my radar went off at 142 mph and it scared the **** out of my wife...lol.. the braking that ensued , that is.. i do have everything oem, but rotors and pads are 1 month old...

 

i know very strange . that is why i went with the DBA in the first place. ill see if the zimmerman warp early too. if so ill check the calipers.

 

as well as hoses

 

brembo blanks are the way to go. maybe if you're doing 100+ all the time like you crazy foos then maybe slotted or crossed drilled are the way to go but brembo blanks do the trick and arent horribly expensive

 

if i were doing it now id go with JHM. Im buy alot of **** from Jason, hes good people.

I the slotted rotors make a big difference in the rain especially. I wouldnt buy drilled though

 

I have steel braided lines all ready and running the super blue fluid. I have always had slotted rotors and this was the only bad set i dealt with. usually i run the brembo as well but i wanted to test others.
