Awesome work from our Victorian cousins.... bravo

[Harry]

Hmmm, there is something on that RDA Rotor concerns me, the way the slotted was done, it gives me shivers.

The slotted groove was all the way to the edge which it is the start of stress point and it will crack the disk then all the way to the mounting hub.

I read it somewhere that it happened already, I think it was Hugh.

you probably read it right here in this thread...

It's been ages. I have been wanting to whinge about how much my new RDA slotted rotors squal with A1RM pads in them :X

Also this happened to one of them :O Warranty is being looked at now :X

caused by the slot extending to the edge of the rotor, which creates a stress riser. the slot should end before the edge, and the end of the slots should be round.

oh, I picked up a set of Evo VII wheels on Friday night too.

Now just trying to decide whether to go the cheap route and use the pair of half worn Bridgestone 215/45s I have and buy another pair to match, or get a set of Kumho KU36 like I had on my previous Supra...

also thinking about painting the wheels dark metallic grey. I think that would look better against the pearl white. powderoating would be better, but costs more too.

That's why I went for the DBA 4000 series rotors, who have a different slotted design to the RDA (crazy photos).

http://www.dba.com.au/4000series/default.asp

They held up quite well in yesterday's run, although I don't think I was pushing it as hard as Scottie or Skurfer since the route was unfamiliar to me.

Kitty, I'm glad you liked the photos

[Harry]

the small slot on them runs to the edge as well. plenty of reports of them cracking on tracked Skylines.

[BuzzPuppy]

*heh* that's pretty full-on. I guess I don't push mine that hard Harry.

[eyeballprawn]

I've heard the DBAs have cracking problems as well.

Ha, I was too slow.. what Harry said!

So what options are there for durable slotted rotors then? Are there any?

[Harry]

these slotted DBA's and RDA's will be fine for 98% of people. Even reasonably hard street driving doesn't punish brakes like track use does. So don't be too worried about them if its street use.

[mookers]

My RDAs keep warping though And I don't punish them...

Well how big is your wallet?

The next step up after the DBA and RDA is Project-Mu. SCR Pure Plus6 if your running standard brakes, or SCR if your using Evo Brembos

Hey people, Wes (Trounced) should have them ready right now. I've sent everything to him and he advised that they would be very easy to make for us.
It's just hard to get in contact while the forums are down.
I'll shoot him an email to check up on the progress of them.
It's been a while since I sent him the design so i'd definitely think they would be ready by now

Don't worry, I'm eagerly awaiting for a set of five to be ready too so I can get them sent over as gifts to a couple of the dudes in Japan.

I'll keep you updated this week.

OoOooOo I'd love one too Which would be nicer? Black or Silver/Grey for a more subtle look?

[Kenneth]

What is usually referred to as warping is actually a result of the pad compound layer that gets transferred to the disk. There is a thread on here about is somewhere, though not sure if it is in the members area.

The point being, it won't be your disks that are the problem, but that your pads are over heating and transferring material to the disk in an irregular fashion.

I'd be interested in the stickers too.. but not sure on what color to get since my car is green/black kinda thingy..

i dont think I want red since i already have too much red in there already..

We have another re-mapping success!!
SA member has sucessfully had a MH7202 ECU from a 98 Galant flashed and installed in his 2001 Legnum. Results went from 160 awkw @ 12psi to 178kW @14psi

ECU couldnt be flashed in the car for some reason (difference in harness between 98 and 01 maybe??) but the flash was done on a bench harness and then put in the car.

Owner is happy (wish it was me, but a friend of mine)

Thanks for the link Kenneth, that is a very interesting read (apart from all the INSERT INTO post VALUES nonsense... it makes it look like someone was trying to do SQL injection!)

I guess my pads and rotors weren't bedded in properly. The first time would be my mechanic's fault, as he said he'd done it for me after installing them. Then after they "warped" once, I had the rotors turned, but didn't realise I needed to do the bedding in procedure again.

They're not too bad at the moment, so perhaps like the article says (if I read correctly) I can find some spot and try re-bedding them to fix them up.

Of course it's not you. You drive a #@%! SUBARU #@%!...

RDA replaced my rear rotors for me and once they receive the broke one back they will let me know what happened.

I have heard people have much more trouble with DBA over RDA...

It was annoying but it's sorted now.

Mine still squeal like a bitch with A1RM pads... even putting on brake lube.

I'm thinking of taking it to my local brake place and see what they say.

All's well that ends well.

[Kenneth]

The INSERT INTO post VALUES is the result of a site crash and rebuild I believe... Thanks for pointing it out, ill go and clean it up!

Fixed up the post. *grumble grumble* damn pain in the backside it was too.

Someone has changed the maximum post length since that was posted. (no doubt because it was originally ridiculously long to begin with)
