the regs are about to change for production cars in aus. brakes are now "free" as long as the disc is the same size and the caliper has the same number of pistons as stock

so i will be putting them on the gtr.

I'm just hoping i can get something a bit cheaper than a custom harrop setup or similar, but I desperately needed to do something about the standard brakes, the brembos are just not up to the job.

Hi Duncan

only vaguely sensible $ option i know of for the 2 piece discs is DBA 5000s made for the R33 GTR. i think stoptech do some that are not as $ savage as Brembo, AP etc and seem to be quite good.

biggest 4 pot is the Brembo F50, you can pick these up 2nd hand on ebay etc as they come off GT-P Falcons (F) but obviously you'll need adapters made. i think the smallest rec F50 disc size is 330 mm but some pad shaping should sort that.

F40 uses same pads but smaller pistons and i think they are a smaller caliper but take the same adapter brackets, not sure where you can get F40s locally / easily though.

alternatively try the jap auctions through Slidewize, Yen is mid 90s to the dollar so 100:1 is a good rule of thumb plus overheads to get it here;

http://page18.auctions.yahoo.co.jp/jp/auction/w15971174 looks to be caliper adapters for F50/40 with 322mm discs. if this is what you need and you got it at a good price it'd be a cheap way of getting some brackets, and you could even consider having the discs binned over there to save on freight if it was economical to do so.

that's all i know of that suits, not sure you'll see much improvement over the Brembos. how do you feel they're inadequate?

cheers

You know what I am going to say.................

Increase the corner speed and you won't have to brake as hard :laughing-smiley-014: :laughing-smiley-014:

Cheers

So increase corner speed, which now means you have a higher exit corner speed, and are now approaching the next corner with even more speed!?!

here's an example of the F50 Ford calipers on ebay. i'm interested in the rears if you want to share the cost.

yep, get some decent (endless, project mu, biot, brembo) 2 piece rotors (324mm X 30 or 32mm) and run some F50 calipers. not too expensive and should be pretty good. and nice common pad shape/size too.

So increase corner speed, which now means you have a higher exit corner speed, and are now approaching the next corner with even more speed!?!

That's what I was thinking. Unless you go even faster round the next corner again

lol thanks Gary. Don't think I can get through corners any quicker with the current setup, so I really need someone who knows good shocks and springs to help out.

the brembos are fading within say 4 laps of oran park, so the changes to the rules are timely for me

We have a set of brakes about the same size as the f40 brembos already (from a porsche cup car, pre 6 spot calipers) that fit 324x30 discs including the adapters, I might give them a go and see if they sort our problems. We have dba 5000 slotted to suit.

Thanks for the options guys.

Duncan, the big question is what is the budget? :O There are some nice calipers that will work with 36mm thick rotors...though they are not cheap. F40s are physically the same as F50s. F50s are really too big to be using on a 324mm rotor...better with something a little smaller.

Pm me your email and i will send you over some places to try

yeah...less than 4 piston can upgrade to 4. 4 or higher has to have the same number of pistons. Very good news for the commodore.

Mark, yeah they were the calipers off Mark's black car (later yellow and purple wreck), might just start with them since we have them. I'm not really just blaming the rotors but I need to go up in size as much as I can overall - these new rules let me run a better rotor (same size) and a bigger caliper so I will go as bigger.

If the porker brembos dont work I'll splash out on some f40s next year.

Gary, I'm surprised the other car didn't have fade problems, they mustered up a fair bit more power than I can.

Hi Duncan, if you've got Brembos you're running 324mm anyway. I reckon the Porker calipers will work well, interested to see how they rate next to the Brembos.

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
