For $220 each, they would have to be the DBA 4000's slotted

These are rated higher than the standard DBA's of course which would be around the $100 each.

I don't know the answer to your question exactly (looking at getting rotors too) but at least DBA have different codes for better quality brakes like the standards, 4000 and 5000's

I don't know if there's differences with the RDA's ??

There's RDA's for an R33 on ebay for $349 which is a significant saving for me over the DBA 4000's but are these the same ratings as the 4000's or just standard rating?

How can you tell? It doesn't say nor do i know how to tell anyway.

Just seems to be RDA rotors, one type, that's it???

Anyone know?

I've searched long and hard on the subject and no-one mentions if there are different levels of performance brakes by RDA. If i go and buy a set, will i just get standard rotors? Or are their standard rotors already performance rotors?

Similarly i can get standard DBA's...slotted even but they're still not 4000's unless i specify 4000's.

So whats thre go with RDAs? Does anyone know what I'm talking about?

Can i get standard slotted and performance slotted?

I want performance slotted rotrors but have no idea how to tell

Hi Birnie,

Gotcha now,

Afaik RDA make only one type of disc. The whole 'performance disc' thing is what DBA uses to market their discs, as would any company wanting to get an edge. Just like 'kangaroo paw' that DBA swear by. They have different characteristics but it's up to you to decide - perhaps considering the experiences of others if you wish - what's what and what works for you. The RDAs seem to have a very good rep, as do DBAs. You can call RDA and ask them straight - even say that you're comparing with DBA and see what they tell you for interest sake. Call DBA and ask them what, and when, you'll notice as a difference in performance between their standard and performance discs.

Thanks mate.

Might give em a call tomorrow.

Why didn't i think of that! 

Get so caught up in the internet sometimes, you forget how the real world operates.  Pick up the phone and talk to someone dummy!

Haha....

Haha!

Let us know what they say.

In dba rotor catalouge there are standard,slotted,wiper slotted and cross drilled and slotted.Then they step up the 2 peice rotors.

Yeah, I've got a copy of the glossy fold out page showing the standards, 4000s and 5000s, explaining the paint colours and all that jazz.

That's sort of what i want to find out for the RDA's too.

Maybe they'll send me something in the mail. Fingers crossed.

I put rdas on my r32 gts4, did a trackday at qld raceway, they worked perfectly well, stood up to my bendix ultimates good. QLD raceway is pretty hard on brakes.

One thing different about GTSt/GTs4 brake rotors vs GTR rotors (besides thickness) is that the vents/vanes in a genuine nissan rotor is directional in a GTR(e.g. L & R) and GTst/GTS4 rotors can go either side of the car.

I don't know if DBA's are directional but my RDA's weren't - not that I noticed, brakes worked perfectly well- on trackday and my mags(not the discs) were over 100 deg C, my tires were between 65 deg to 85 deg c too. I could not complain about the heat performance of my brakes - pads or rotors.

I only got the std ones for my car, they were $75 each in Brisi this feb. It was $125 for slotted as they just slot the std ones for you, it gets done by the factory I'm told.

definitely worth a try.

DBA 4000 series slotted rotors are definately directional for all cars.

When you say non-directional, does that mean the slots go straight out from the centre of the disc? Because if they are at an angle, they are directional. The "sharp pointy end" of the slots (at the centre) should point in the direction the wheel spins, so that the slots can release any gasses as they spin.

im getting rda rotors on my r32 gtst today! yay no more brake shutter!! lol any ways i was getting slotted front standard rears but he rang me up and said ohh we've got no slotted left in stock blah blah you can have there new ones which are still slotted but the have like little bumps outta them there a bit better and only cost 6 bucks more so im like ok so ill see how they go and report back! :D

I wouldn't say bumps, more like dimples.

Spoke to RDA (or EBC today, they merged)

There is only one type of rotor.

Asked what temp they're rated too, not sure...hmmm?

Warranty is voided once you hit the race track, don't know about DBAs if thats the same

The new ones you're talking about are on this page..

http://www.ebcbrakes.com/Automotive.html (near the bottom)

Was also quoted $368/pair for normal RDA slotted rotors

and $455.90 for the NEW type slotted/dimpled EBC Sport Rotors

That's for a pair of R33 front rotors.

The new ones definatley look interesting !

They make some interesting points about the y new type.

The slot is wider as it could normally get filled with dust or rust preventing it's gas removal purpose.

Also, iodised to prevent rust.

And dimpled, as opposed to cross drilled to stop cracking.

What do people think of these little beauties?

    • Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.
    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
