Are You Cracking Dba Rotors?

[MrStabby]

I just took a careful look at djr81's rotor photos - on my as yet uncracked DBA4000s, the slot is NOT machined all the way to the edge like it is in those photos. It stops a few mm short. Perhaps they updated the design?

[djr81]

Photo of yours?

[Ant97GTR]

djr...they don't make 5000's for the rears which is why I was considering 4000's

Also had a look at greenline and nengun and for the life of me I can't find mu or endless rotors for the rear of a 33....am I going blind?

[djr81]

No you are not.

Sorry for the bum steer. I thought they did. Dodgy memory.

I think the reason is that the handbrake works on the inner drum section (or hat if you like) So no one makes the hatted rotors for the rear.

They dont make any 5000 series at all for the povvo pack 32 R's either.

Except for a mob called Biot who appear to.

Hmmm so you can't get rear rotors from greenline/nengun and the RDA's and DBA's crack with track use....

Whats options am I left with to replace my worn stockies then?

Sorry about the poor quality but you can just see it;

You can get plenty of rotors, just not hatted ones. Check the usual imports mobs. Endless/Project Mu. With the way the dollar is going lately they will be practically giving them away....

The Biot stuff looks well bling if you can get your hands on them.

Maybe AP or Brembo do one also. Big $'s, but.

Actually looking at the difference between djrs and mine it looks like they may just machine the a 324 to bring it down 296 - look at the way the vanes go all the way to the edge on the 296's and are smoothly machined, where as the 324 still have the cast finish and stop well short of the edge. Perhaps they further machine poorly cast 324s to make them saleable as 296's....

Reckon you may be onto something there.

Notice also how much wasted rotor face there is on the inside of your rotor.

just because nengun says so doesn't make it true. I have bought from project mu scr pro rear rotors for BCNR33. yes they are 2 piece and have the drum built into the hat.

[djr81]

Maybe we need a group buy happening to bring in a shedload of hatted rotors.

Looks like every man & his dog has problems.

[Snowman]

They aren't the same size as discussed here but backing up Richard I have 2 peice rear Alcon rotors with the drum built into the hat also.

LOL...for the rears im thinking std Nissan with some home made slots machined into them

Im all for the fish hook or long curved slots like the G4 as there are less likely to be stress concentrators.

Im just going to sell my car and get a Mk 1 Escort. Single piston sold rotors are less complicated and up to the job when you have a 650kg 180hp car

Lol Baron....I wasn't suggesting that to be the case....I just need to find someone who will supply me the rotors here in Oz.....does anyone know who I could contact?

[32R]

These guys may be able to help.. http://www.racerindustries.com.au/

[Nemesis]

Well guys I'm running Project Mu SCR rotors and Endless SSS pads all round on my r33 gtst... no cracking as of yet, the rears work fine but the fronts screech/squeel something cronic. Any theories to why this may be?

Sorry to bring this up again, but from where did you order them? I can't find anyone who either lists them or is willing to admit they can supply them...

[MrStabby]

More DBA gheyness, crack in the usual spot. Obviously doesnt matter that the slot is not machined to the edge.

I've got the G4 330mm kit now.

[Roy]

And DBA are not talkign to me now, perhaps they dont want to lie as their investigations may have revealed that my installation was in no way at fault

Anyway, if they dont do something to stop the failures or at least properly educate those installing them then they are going to continue to lose lots of business, shame really. I woudll rather run used std Nissan rears then anything DBA, and its not because of money, just confidence in th :(e std product doing a better job then anything dba sell

[Beer Baron]

yeah I'm off the DBA wagon that's for sure.
