Disc Rotor

[Wing]

i am planning to upgrade my brake disc, but i don;t know if i should get the DBA Longlife Slotted or Longlife Gold, which one has better performance???where can i buy them and get install it, and how much is it???:shake:

I have heard of DBA golds giving a little trouble in the cracking department, however I have driven 51 jay's R33 with standard discs, good fluid and a set of NA-r (I think that's the code) Endless pads - cold. This set up would have to be good for at least a 400hp car used for sprint circuit (unlesss your car weighs two tonne).

Just a set of Slotted rotors with endless pads (even when they are cold) would be nearly over kill (even for track) unless you have an unlimited budget for brakes.

If your using them for the track, stay away from cross drilled as they are prone to cracking. Slotted works best.

However if it's just for the street, either one will do. I've had a set of longlife gold on my WRX and they we're a treat with bendex ultimates.

cross drilled on the track prone to cracking ? why does the porsche cup cars use the standard cross drilled discs then, also most other performance cars come with cross drilled rotors ?

[red900ss]

Because Porsche and Brembo know a thing or 2 about cross drilled brakes.

dba do not recommend their cross drilled discs for track work.

Wing, check out the dba 400 series rotors. I'm getting these next week and there are some others on the forums who already have them.

There was this group buy thread last month, you could see if they'll still do the same price.

Yeah I got my 4000 series through the group buy. They are a nice looking slotted rotor. I have put new bendix ultimates with them. Can't wait to test them on the track. Next track day is not till August though so I will have to wait. They do look very cool though.

Nismoman - Brembo rotors are way better build (and way more expensive) and maybe no slots (just cross drilling) is different to taking chips out of the rotor at all angles.

Wing - Slotted rotors with good pads and good fluid ($30 a bottle) works great. Braided road legal lines - even better. If youre using slotted you dont really need cross drilled. Im talking from experience with the DBA slotted rotors you are referring to.
