hey guys

got my 34 4 pots ready to go on an i was just thinking, can i put the stock 2 pots on the rear?

i know of a tracked 31 that has 32 fronts on the rear (i think)

so would i be able to swap my 2 pots to the rear?

anyone tried this before? any success?

thanks

Tom

i'm sure you find that the mounting points for the rear will not accommodate a front calliper. you will also probably run into issue's finding a suitable rotor that will fit the offset required for the calliper, and also have the deeper hub for the handbrake shoes. i would also think that by putting a set of fronts on the rear you will probably stuff up the brake bias.

if your after a cheap upgrade for the rear just get a set of R32GTR or R33GTST ones, they are a lot more common that a set of R34GTT rears would be.

yeah but if you think about it gtst rears are 297 (fronts are 296, if i'm remembering correctly) and the gtst (or gts25t) rears are 2 pots too

i'm upgrading to 4 pot fronts so moving the 2 pots to the rear should help ballence

i'll contact the guy running the front on his rears and find out if he is still retaining the stock handbrake

so for the moment it seems like a no go, i shall delve deeper

it doesn't quite work like that though. the last thing you want is to reduce the braking force to the fronts by increasing the size of the rears to something that could throw out the front/rear bias percentage (bmc can only dislplace so much fluid)

nothing wrong with just upgrading the fronts and leaving the rears though, as most of braking force is through the front wheels

as said above, just get the rears from a 33 gts-t and save stuffing around

This is sillyness. If you want to do the rears use r33 gtst. If not as Mike and qwk32 have said just leave the rears as is and upgrade fronts. Buy decent pads, adr braided lines, slotted rotors and upgrade bmc - end of story. Most people do this for the visual aspect and there is no real proof this upgrade is better than a well setup stock set of brakes. Going better like Brembos wouldnt be justified on your rig atm. Watch low pedal position and handbrake issues. Use the search function and read brake threads by other members for more troubleshooting info. If you are after a excellent jap pad and quality brake products I recommend Acre. As I can swear by their products for daily driving.

Never mind delving ...just take your wheels off and have a look - they won't fit.

33/34 rears share the same caliper/rotor combo if I remember correctly, fronts share the same caliper internally (With longer mounting arms to the hub) but a different disc size. 33 rears can be had for a (relative) pittance, as everyone loves the brembo brake upgrade, and there are always plenty of 33 GTS-T's wrecking. I would go for the 33 rear set-up if you really wanted to double the amount of pistons. I can attest to the rears being a direct bolt up to S1's, I'm sure they would be similarly easy to bolt on to S2's.

I got my front and rear 33 set-up with Calipers/Pads/Rotors (Pads & Rotors near new) off of a rolling part-out 33 GTS-T (defected) for $380. Start searching the classifieds :D

yeah i'll just leave it

maybe i'll redrill the rotors and put the old 2 pots on my 31

got my 34 fronts with pads, lines and rotors for $400

i'll see how they go for now then

just gotta find some metalcast paint :D

upgrade bmc and get a bmc stopper :D

When i fitted the GTT brakes I found the master cylinder worked fine but I see that some people have replaced it - presumably to reduce the pedal travel (although increasing the effort required).

My S1 has a BM50 - what are peope using who have upgraded and from which vehicle are these available (or have you paid the brand new price)??

I bought a cusco new at around $150 (Part no: 232 561A). Pedal feel was higher, less spongy and more responsive, but i had a full overhaul to stock brakes so hard to tell (comparing GTT fronts.) Dont know about using second hand stuff here (10-15 years old) but a GTT/GTR uses a BM50 and GTST uses a BM44. Brembos are BM57 and it seems that a 300ZX BMC uses that same bigger cylinder diameter - 26.9mm vs 25.4mm respectively?

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
