I have just been pricing some rotors and pads to buy. Where is the cheapest place to get them, also the Bendix Premium 1398BP seem to be no longer available at most places?

I can get the pads for $121 and rotors range from $252 to $315 each for the same ones, DBA 4909 SR ans SL.

Can I get them cheaper?

Try the 1250 part numbers, they are more common than 1398.

Do you need the rotors desperately? I am working on a Group Buy for DBA rotors and it is going to take a few weeks as I have to complete the tests on the machined to size rears.

:P cheers :D

How much will the savings be ... around about price??

Hmm might just wait then, I take it group buys are by cash, not credit card?

Yeh, that's the $1M question, if I knew how much they were going to be I would have finished the Group Buy and posted it up already. I am hoping for 15%, so that will make them around $800 for a set of 4. There may be a little bit more for machining the rears to size. Group Buys I arrange are via direct transfer, it makes the process much easier and the price cheaper.

:D cheers :)

The DBA 4000 series rotors come with temperature sensitive paint on the rotor edge.  This is the DBA instruction sheet for what the temperature sensitive paint is going to tell you.

DBA_Temperature_Sensitive_Paint.jpg

There are 3 colours (green, orange & red) and they change colour (white, yellow & white) at different temperatures. So I will be able to tell how hot the rotors have been. This will tell me what pads and what brake fluid to use.

I will post up some pictures of the temperature paint on the rotors after 2 weeks use and work through what it means to my future choices of pads and brake fluid.

:D cheers  :O

Quick update, as you can see from the following picture, the green paint (458 degrees celsius) has started to change colour. And the orange (550 degrees celsius) is slightly more yellow. But the red is still red, not white.

I would say I haven't had many brake applications that have resulted in spot temperatures over 500 degrees. I haven't done any real heavy duty towing since I installed the rotors. So I will do another update once I have done that.

:D Cheers :D

1. What are the benifits of slotted over normal discs?

2. Do they go through pads a lot quicker?

3. Is the benifit really there?

Suggestion follow;

1. As the pads heat up they give off gas, this gas forms a layer between the pad and the rotor, lowering the CoF. Also small particles of pad compound form a layer between the pad and the rotor, like little ball bearings. The slots scrap off the partiles and allow the gas to escape. Hence you get superior pad to rotor contact and improved braking peformance.

2 Not really, the slots remove stuff that is no longer attached to the pad, they don't remove pad material itself.

3. No it's a wank :D that's why race cars use slotted rotors. It's the rice factor, nothing at all to do with improved braking performance. :D

:( cheers :D

for anyone wanting 328 mm rotors the gtr ones are str8 fit (with brembo calipers also bolt on) and are huge in comparision to stock 280mm ones :P

gotta love nissan and there same hub designs etc so all the brakes are interchangable on most models :O

can slotted discs be machined? or is that not a option on them......

im assuming they will still require some maintainance, in the course of its life...

Yep, they can still be machined, down to the mimum thickness of course.

:P cheers :O

Two questions:

1. Brad, how much were the GT-R rotors, and did you by chance happen to get a price for the single-piece units (i.e. not using the separate hat and rotor configuration)? And do you need 17" wheels (or bigger) to clear them?

2. SK, if doing the mods bit-by-bit, what would you recommend as a starting point and where would you go from there? Is it worth changing calipers too, or are the standard ones holding up well so far under the loads that you've put on them with towing, etc.?

By the way, gents, both cars looks good. SK's with the R33 GT-R wheels (I might consider these myself eventually) and THAT RB26 in your car Brad - what a dream!!! Even better that it looks pretty much stock apart from the wheels.

I love street-sleepers! :)

Thanks in advance,

Hi Nick, the improvement from using the DBA slotted rotors, some decent pads and bleeding the brakes is quite a lot. I can easily outbrake (activate the ABS) with the standard wheels and good 225/50/16 tyres. Thats' with the suspension upgraded and proper alignment as well, so there is plenty of traction. I haven't tried it with the 17's and the super stickies, the tyres are still a bit new to abuse them.

I was having some problem with brake fade when towing in stop start traffic. But that was the compliance pads and brake fluid, I haven't had any problems since the upgrade. I haven't felt in danger of hitting things like I did a couple of times previously. For $800 or so, it was well worth it. If the pad compound isn't up to it, I have a more aggressive, higher temperature and CoF option that I can try.

I don't realy think I will need to upgrade the brakes anymore than that for my purposes. I simply can't justify the cost for what I use the Stagea for. An example, for a set of R33GTR callipers (not Brembos), a rebuild, slotted rotors, new brake hoses and decent pads I would be looking at $2K. I can easily spend that money on parts for the race car, that I know it needs.

:P cheers :)

PS; the height looked good at 340/330 mm but it was a bit low, scraping on some speed bumps (with the standard exhaust) and occasional bump stop hitting. Particularly in the rear with 200 kgs of load. So I have raised it up 8 mm (one circlip groove) front and rear, I have also backed off the front stabiliser bar a bit.

I will try that for a week or so and see how it goes.

hey nick cheers for the comments :) it looks and goes good.. when it goes, wait till the rebuild is done and ill be testing the strength of every stagea component i can tell u that hehe :)

ok the gtr 328mm rotors with alloy hat are retail $600 each side, i managed to get them through a friend who has an account with coventrys so i paid $480 each side.

note the gtr rear 300mm rotors dba slotted one piece where about $300 each so i think the alloy hats jack the price up alot :)

the 330mm rotors and brembo calipers only JUST clear my 17' rims luckily :(

heres a few pics up close...

Repco sell the DBA4909 slotted rotors for $217 each.

They also sell the Bendix Premium 1398BP front pads for $125 plus shipping from QLD.

Do they actually have stock of the Bendix Premium 1398BP's? I'll take 2 sets if you can get them. I had our local Repco guy search through every branch looking for stock. He only found 1 set, they were in Adelaide on the computer but when they went to get them, they weren't physically there.

:) Cheers :)

PS; The Lucas European pads stop well, no squeel either, but (like all European pads) they make brake dust, lots of brake dust.

Have you guys called up these guys:

Brake Distributors of Australia

(07)5569 2207 or 0414 868 555

They sponsor the SAu QLD club and are DBA dealers. I have dealt with them before for my old 33's brakes and found them great on price, but I got a discount for being club member of course :)

Hi SK,

I got my wife to do the legwork and ask for pricing (Im at work, she was getting fuses for my abs/4wd problem), word was that there was a set in Queensland.

Maybe I should snap them up!!! :lol:

Yep, a few months ago. They don't carry stock of Stagea pads (no surpise there) they just get them on order from Bendix. But Bendix don't make them anymore so they don't have stock themselves.

:) cheers :)

    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1680, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.
