Rotors

[chockz]

Hey guys,

i'm need to upgrade my rotors as my they ain't dissipating heat fast enough for track use. I was recommended to keep my calipers, but upgrade to slotted disc brake from DBA.
Anyone done that before? Or anyone has other recommendations like use (DC2R or some other brand rotors)

thanks

DBA are fine for us budget users,
but u can go higher and higher just depending on your budget,
eg Project mu, wilwood etc etc.
dba will be fine with the right combo of brake pads

[blk_shadow]

for budget use, probably just go with dba slotted and ebc green stuff pad

[chockz]

yeah u guyz know any particular model?
i was thinking it was worth getting a 2nd hand DC2R rotors ( i don't even know if they match???)

i was thinking of getting mu secret ..hmm...i will think abt it when the track day comes..anyway..how much roughly is a DBA or RDA rotors?

so it sounds like your getting brake fade after a few laps on the track.

IMO your going to have a much better result with higher quality pads.

So out of interest what pads are you currently using? And how many laps do you brakes currently last on track?

Really you upgrade rotors to gain more bite (braking force), its not until you increase rotor diameter does it make a decent effect on how long your brakes last (increasing diameter also increases braking capabilites). Another good option would be to upgrade your brake fluid (to what i dont know).

BTW, pads are cheaper than rotors

What pads are you using now for track? What brake fluid?

Upgrade as in same size rotors, but with slotting?
Won't help with dissipating heat.

If you're staying with OEM size rotors:
1) higher spec pads - make sure they're bedded in properly.
2) remove the backing plate/dust shield. Will need to wrap ball and toe links
with heat reflective tape.
3) brake ducts. You'll have to DIY these yourself.
4) Get an adjustable proportioning valve (need a twin circuit model $$$). Honda has to set brake bias very much to the forward wheels
so in bad conditions (wet), fronts lockup first. On a track your rear brakes could quote easily take more of the bias.

If you're going larger brakes, either get a brake kit from WIlwood, Brembo or Ap racing and
pay $$$ or install integra dc2r brakes.

1) dc2r rotors, will need to be re-drilled to suit your pcd. 1996 itr rotors are 4x114.3mm and
make it easier to re-drill without overlapping an existing hole if instaling on 4x100 pcd.
Doing this may spoil the balance of the rotor (Thank Yonas for this tip!).
2) 17CL15VN ITR caliper and caliper brackets. This caliper also came on other vehicles
which will lower the price dramatically.
3) pads. Lucas are my pick. Ultimates have a few fans. If tracking car then step up to
Ferodo 2500 ($$$). There are of course MANY others. Lots of threads on Ozhonda.com
about this very topic.
4) 1" master cylinder off ITR. 15/16" may work and a bolts on to existing civic booster.
1" MC has different bolt pattern and requires ITR booster.
Apparently 99+ ITR MC is the MC of choice because the hard line configuration is
the least different amongst the 1" mcs.
5) possibly a 4040 propotrioning valve.


Here's a link to a web page with lots of OEM parts brake upgrade. I'm assuming a civic vehicle
here.

There's a dc2r setup going on ozhonda, but I don't know anything about kit or seller.

RDA (taiwanese made) is cheaper than DBA (jap made)
I think RDA is roughly below $200 for a pair

[Zilli]

ive got second hand ITR rotors for the front that can be redrilled, and also ITR pads all round that i can do for a good price for you, see my for sale thread mate

damn, i always thought DBA was an aussie brand...

i guess u learn something everyday...

[nigs]

DBA = Disc Brakes Australia.... =\
Though the rotors are probably no longer made in AUS.
Same goes for RDA. They're no doubt made in China.

IMO, RDA rotors are fcking weak sauce.
You really do notice the difference in build quality.
Price wise, DBAs will be nearly double RDAs.

Shame I haven't been able to hammer the shiet out of RDAs yet.
I'd give some feed back but alas brakes are teh borked.
GG aye.

Great post

Actually you can buy 4x100 pre-drilled 282mm sized rotors. I'm using some Taiwanese branded Exzess.
