Here's something i pulled off autospeed

AutoSpeed: What are the advantages of drilled discs?

Steve Borg: They dissipate water and dirt, degas the pads (giving better braking distance) and also stay moderately cooler. But that's not an issue - I don't think - for street use. We guarantee our drilled discs to up to 700 degrees C - and they will withstand more than that - but you'd never exceed 450 degrees on the street. On the racetrack you'd probably get up to 600-700 degrees. Again, though, our rotors aren't sold as racing discs. And, of course, our drilled discs look the part - especially behind mag wheels. The slotted discs perform exactly the same and do exactly the same job - getting rid of the water, dust, gasses, deglazing the pads.

AutoSpeed: What are the disadvantages of drilled discs?

They are a little bit noisy - you do get a whirring noise. And, with our drilled and slotted rotors, you do lose about 10% pad life. In saying that, you gain in rotor life because the pad won't bite hard into the disc. If you let the pads glaze up, their material becomes harder than the cast iron of the rotor, and it then starts to bite in and create grooves. But, with slotted and drilled discs, that doesn't happen because you've always got a nice fresh pad surface running over the disc.

AutoSpeed: We have seen several sets of cracked drilled discs - how do you explain this?

Steve Borg: Look, I keep myself fairly fit, but I'd be crazy to jump out of bed and do a sprint without warming up. It's just like you don't take an engine and go racing without warming it up. It's the same for rotors. They're cast iron, they expand when they get hot, and you really need to warm them up before working them. Abuse them when they're cold and they'll crack. You don't have to warm them 'till they're red hot, so long as the heat sink is right through the rotor and it's not just the outside surfaces getting hot, it's fine.

I have PM'd dsturbd several times but looking at his profile, he's not been online since 9/5/04. I only know him through online chats so I can't really move this thing forward any more than its going. Gives everyone some time to save $$$ i guess. I'm still in need though...

*****WA ONLY SORRY******

Hi all,

One of the forum members here in WA, Dsturbd, has kindly offered to hook some members up with a great deal on brake components, in particular DBA 4000 slotted rotors and matching performance pads. I know i'm in need of some and a few people have also expressed a casual interest so I figure a group buy may be in order.  

Pricing has not been confirmed yet and obviously depends on numbers but bank around $250 each rotor and $65 for a set of pads. (Purely guesses)

If you are interested, please note your interest within this thread. I'll post more info on products and pricing when available.

I'm interested, let me know how your progressing.

Products:

DBA 4000 series Slotted rotors (no cross drilled as they tend to crack)

Bendix Ultimate Pads  

Green Stuff Pads

:)  

Dave

Brett, heard from dsturbd on Wednesday who has been on holidays for the last little while. He said he'd have prices up on Thursday but so you can see, haven't seen anything as yet. I sent him another PM yesterday. Trust me, i'm on to it as much as i can.

Prices are in!

$245 for 4000 series rotors

$45 for bendix ultimate pads

$230 for greenstuff pads

$180 for feredos pads (which dsturbd tells me are better than greenstuff)

$65 ltr for Elf brake fluid

If you would like to acquire any of the following, please PM dsturbd directly and he will order and arrange payment with you individually. Just mention the SAUWA group buy and he'll give you these prices.

Cheers!

Dave

    • You’ll want to have the block drilled and tapped to suit 1/2in head studs and the head for the same. How much power do you intend to make?
    • Sorry for resurrecting an oldish thread Not much has happened in the past year since the last update. The car did another 1000 miles or so and failed the MOT for the first time in October (failed on tyres which had been advised for a couple of years) In October the car got put up for sale and was removed in November due to no interest, being so close to christmas it was to be expected. The roads were dry in February so I decided to tax it early and get the new tyres fitted.   Fast forward to April, I got someone in to give the car a good clean after sitting for the winter.                                 The car got re-advertised and today (Saturday 3rd May) the car sold. The new owner is planning a GTR conversion at some point and a respray in the same pearl white. It's bitter sweet, it's a shame to have the car sit there for half the year and then only do 1000 miles. The kids are growing too quick and space in the back is getting limited. It's been a great 6.5 years of ownership
    • And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.
    • No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.
    • Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.
