I have a R33 GTS-T and am currently looking at the 2 and link of Alcon front and rears (365 front and 350 rear). The car is now 100% used for racing and sprints.

I am a real noob when it comes to this stuff.

Will these fit under my P1 racing 17x8 rims with a 22 offset? I am also looking to buy a couple set of Enkei's rims in 17x9 and am unsure of what offset I will need to fit these brakes and the car without cutting or flaring the guards.

Highly likely that it wouldn't fit

P1 racing will barely fit GTR brembos, they dont have much brake clearance so i'm fairly certain they wouldnt house the alcons

Thanks, I will do some more research and use the cut out template to see if the 343mm will clear the P1's. I am looking at keeping the 17x8 on slicks for transport and sprints and use the 17x9 on R comp tyres (rules are rules) for racing.

So you are in Melb? So how many track days are you seriously going to be doing every year? If its 2-3 then that is very different to 7-8. Places like Winton are far easier on brakes than Sandown and Calder...are you going to do Sprints or just drive days?

What are you running in the way of pads and fluid now?

Thanks Roy. I am just getting a feel for my setup but my intention is to do at least 10 a year. its a full weight if not heavier with the sound proofing (showing my age) and is currently on a very conservative tune of 340kw which I will be probably push above 400 as I play with it. But even at this level I am getting brake fade when pushing it through the twisties especially downhill. So I could imagine my first trackday will be a disaster. I am happy to take your previous advice and give it a go on standard calipers and your recommended rotors and pads. No sure on the current rotors and pads but can't see them lasting at track temps. don't care really about squeal or dust but wouldn't want no streetable performance as i do use it as a daily when I am in the mood. Thanks

I am using a set of 330mm x 32mm 8 pot D2s on the front of my 1800kg Stagea with 17 x 9 TE37s and they pull up fine with no drama time after time from 250km/hr on the back straight and about 230km/hr on the front straight at Pukekohe. have also used them at Hampton Downs, Taupo and Manfield circuits. I just have GTR 2 pots on the rear, a GTR Master Cylinder braided lines and Motul RB600 fluid. Would think that would be fine for a slightly lighter GTR.

I'm running 34 sumitomos on my 300z. I've had dramas with pulling up, glazing the front rotors.

I have a pair of F40's with custom 2 piece rotors but it's for my A70.

My plan is to utilise what's there already. The bias is good. I hit up GSL rally sport and bought a front and rear slotted set and 1ARM pads.

It was really cheap hence why I jumped on them. Because the pads are fairly soft I'll be going through more pads than rotors so it's economical. Also running high temp fluid.

I'll be running some ducting to the front and see how I go.

Like others said maximise what you have already. Don't go project mu rotors... WAYYYY to $$$

You could get ones made up for less than that.

Yeh, it varies so much car to car and person to person. It woudl nto be strange to have trouble on street but not a track. Depending on the roads and the tracks etc. But on a track like PI and Winton there is only really one or two stops that rqequire you to brake for more than 3 seconds...on the road you often cant carry the corner speed you do on the track so need to brake more frequently for longer periods without the high speed bits between that really gets the cool air flowing,

If the thing is borderline on the street though than I expect you are right and you will struggle on a track like Sandown. Places like Winton and I suspect you will be ok, well at least a lot closer to ok.

Frankly, I would throw a set of pads and good fluid at your current setup for your first few track days. Minimal cost and will give you a chance to just get out there and see what you like re feel in brakes with a different pad.

Having had numerous setups on my car and I can tell you about 90% of brake feel and performance is the pad. I suggest something like a Hawk DTC-70s...high temp race pads that you can get cheaply through the US for Brembo equipped 350Zs....you will most likely get a soft pedal from boiling fluid than fade from over cooking pads and rotor temps. So just take an extra bottle of fluid to the track and give it a light flush every session once things have cooled down.

Since you need to change pads anyway to start doing track work than thats a sub $500 solution to getting out there and being able to enjoy the car and get a feel for just what brakes you are going to need. You could find the money saved on brakes could be far better spent on suspension or tyres

Hi Roy.

Just confirming before ordering. Can you please clarify from the following list. You mentioned the 350Z pads that I note are cheaper than the GTR pads however there are multiple selections. Can you confirm the pads that you suggested above.

Thank you

Yeh its odd. I have never asked the question. Perhaps ring Project mu distributer and ask why their R34 and brembo equipped 380Z pad numbers are different.

But they are the same pad shape so go with whatever is cheapest...which is why I recommended the 350Z stuff. I ran 350Z DS3000s with the R33 GTR setup I briefly ran

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
