Just side tracking a little here Steve, I've got a question.

What brakes better, a 300mm disc with x surface area brake pad, or a disc with 333mm disc and same x surface area pad?

Also for better performance, would you make a bigger pad, or is bigger disc more effective?

A larger diameter disc = greater brake torque

Larger disc mass = better heat capacity

Larger surface area pad = longer pad life

It depends on what improvements you are looking for.

G'day all,

I had a similar problem with my 32 GTR. 4 hard laps

@ Wakefeild and my peddle went like a limp chicken!

:lol:

I'm was running Green Stuff up front and standards in

the rear (later I found that they were down to the steel)

I'm going up to wakefield again on Friday. so.....

I believe the brake fluid is what let me down?

I have put Kevlar's in the back and cleaned up my fronts!

Should I flush the brake system and go to DOT 5.1? or stick

with the DOT 4?

Steve, are these new rotors available to us humble aussies?

R,

Adrian

Yes they are!

There will be a two piece version available soon too. Prototypes are sitting on my desk.

I would look into better pads too. Ferodo DS 2500 or DS 3000.

Steve,,,I have your sloted and drilled discs on the front of my R33 GTS-T using Greens. The cars brakes are WAY better than standard. I'm as happy as a pig in shit!!!!.My problem is,,, I have been waiting for a set of sloted rears for ages now and I MEAN ages. Am I being stuffed around or are they actually available.

I'm not interested in trackwork by the way.

Neil.

294 and 330mm?  

will these suit for street driving and the odd motokhana when coupled with greenstuff or race gear pads?

We are still working on this one. We have found 3 different front rotors so far for this model.

1. 296mm x 32mm = DBA 926

2. 296mm x 30mm = ?

3. 310mm x 30mm = ?

We have samples but we have not alocated numbers to the last 2 yet. We need to confirm model specs for each part.

The rear is the DBA 908.

so what's the part number for it heheh :P

cheers

Joe

70 new part numbers this year my friend and another 50 being assessed. This takes time even at 15 hours a day. If you would like to order 100 to 1000 rotors I can move it forward otherwise its a Christmas job for me.

We missed our window of oportunity earlier this year, so this is the next one..:)

I'm very interested in new Skyline rotor developments. Kangaroo paw style rotors are what I'd mostly be interested in, but I can't decide if I'd want slotted or not (depends on the pads I upgrade to I guess).

Steve, is the DBA website updated often? The last time I went there a few weeks ago, I couldn't find anything other than standard rotors for Skylines. Maybe I just wasn't looking hard enough, is there a direct link to new models of Skyline rotors?

I too are looking for a rotor upgrade in around 3mths time. Im sure what i currently have (standard rotors just recently machined) are fine for my driving (10km stints of start/stop) but in that 1 case that i do need to brake heavily i want to know that my gear can handle it.

No idea about any of this stuff, when i recently got new bendix pads on the back i was looking at those yellow dba slotted and cross-drilled fitted for about $1,400 or something ridiculous.

Anyway thats my story.

I get in trouble for this all the time.:P

Because I use these forums to get information on upcoming projects you guys know about new products before marketing. We are still working on the GTS series so additions will be made over the next few months. We did the GTR first because of overseas demand. I know a link has been set up for a Skyline specific page on the website but I don't believe the information has been compiled yet. If you go to the WRX page you'll see the format we will use.

whether or not to go with slotted rotors depends on the type of driving you do.

      Borg Warner EFR Series Turbo's V 2.0

      Turbomachinery engineers. They're just mechanical engineers who generally studied in universities focused on oil and gas, aviation or that had a formula SAE competition team. We have an entire team of them in our engineering department... they geek out over data and performance testing. I worked with them a lot when we developed an anti surge system for centrifugal compressors ran by electrical motors (~20 000-50 000HP) to avoid surging on accidental power loss.  They laugh when I mention automotive turbochargers.... it seems they're lightyear's behind in technology due to poor funding. If you think formula 1 spends a lot of money, a single turbine/centrifugal compressor package in my line of work including the balance of plant equipment generally ranges in the 150-250Million range depending on size.

      The diff brace did not increase NVR at all. And yea the whole reason I thought getting the rear diff brace was a no brainer was because of the reduction in wearing the bushings out + wheel hop. It's a cheap mod for a big cost mitigation in the long run. I bought it for $99 USD + shipping. In regards to the sway bar - i had some over/understeer going on but i just checked my tires and they are pretty worn out. I wont be changing them til july since i'm away for work for a month or so. will sort it when i get back and do more testing. But its definitely still a big thumbs up from me given how planted the car feels now and me being able to go around corners quicker. Still puzzling to me why they never put a LSD into these cars....even the 400z. I saw this mob selling LSD kits for a decent price though it's a little more involved on your part to get it installed: https://www.tractionconcepts.com/Infiniti-Q60-R190-Limited-Slip-LSD-Rear-Conversion-p/tcxin9240.htm

      Great for thrashing on the track - particularly if it is all corners. Otherwise, it is a recipe for massive tyre wear and reduced straight line traction. -1 is plenty for a streeter.

      There are other MAP tapping ports. There's one that runs to the boost gauge MAP sensor on the firewall (over in the corner behind the brake booster). Start at that sensor and follow the hose to the plenum.

      Japanese circuits have always looked tight to me on Youtube vids. They seem to be able to fit tracks into the smallest of spots. I've never experimented with camber in the rear. I'm running similar front camber to you (albeit in the E90) but I've been looking into what options I have in the rear. -3 rear seems like a lot. Yeah, mine is the N54. I had an N52 330i for about 7 years, it was awesome but I just needed a little more poke. The N54 is also DI. I'm running BC coilovers with the M3 front arms and a Whiteline front sway bar and the turn in and ride quality is brilliant. But I do still suffer from a bit of roll so I've been looking into that lately.
