hey guys, have a 32 gts and was looking at putting 32 gtst rear brakes on it. i got hold of some brakes, lines and rotors that came off a r31.

which i thought i killed 2 birds with 1 stone with getting 4 stud rotors.

BUT turns out the center of the rotor that goes over handbrake shoes is to deep and when wheel is tightend up fully it fowls the hub and

wont let wheels spin >_<

so just wondering what rotors i need to get? 32 gtst 1s and redrill to 4 stud? has anyone else ran into this issue?

should also add that front is already upgraded to 32 gtr calipers and rotors before people think im a total nut lol.

thanks in advance

beau

im thinking the best/easiest/cheapest upgrade for you would be to throw on R33 brake calipers/rotors/5stud hubs etc, that would open up a whole lot of wheel options for you as well, the 31 stuff taint the best especially the handbrake setup

sorry i musnt have made sence.

the only thing 31 is the actual rotor, standard 32 handbrake set up and 32 gtst calipers...

only reason i tried those rotors was cause they are 4 stud already.

not too keen on goin 5 stud as i have a set of LMGT4's on it now which i think look good!

thanks for your reply though dude.

cheers beau

The majority of the breaking effort is taken by the FRONT brakes. I can't see any great benefit in changing / upgrading the rear brakes.

Not quite...

With regards to the rear brakes, probably the biggest mistake people make is neglecting the rear because they beleive it does less work. Yes it's true that the rear 'axle' as a component does less of the overal vehicle braking, but it's also got substantially smaller hardware in which to do it with, so the actual 'brakes' themselves can often work nearly as hard as the front ones do. What can happen if you neglect the rear is that end starts to fade out slowly without you noticing, and it puts more pressure on the fronts, which causes them to fade, and people blame the front for a problem caused by the rear.

Yuh, the overall lesson is not to upgrade the rears on their own, but if you do a reasonable upgrade on the front then you should upgrade the rears as well if you can.

Even a smallish upgrade on the front will change the balance. I was convinced I had too much rear bias with standard R32 brakes. Same pads all around, which was probably the cause - I think OEm pads use a better coefficient pad material on the front. Anyway, put R33 calipers and discs on the front, so a small overall upgrade, but significantly changed the behaviour of the car. Wasn't so likely to lock a rear brake any more (especially the inner rear when late braking heavily into a corner). Much improved the balance in my estimation. If I were to use adaptors to push my front calipers out to use 324mm rotors, I'd start to worry about overdoing the bias change.

interesting replys guys, making me think i should get these rear brakes on, as i have 32gtr fronts and 32 gts rears.

that cant be good for the balance... :O

so back to 1st question has anyone upgraded 32 gts brakes and what to and how did they go about it???

cheers beau

Well, the answer to that question would have to be another question.....Wouldn't it be trivial to upgrade to GTSt brakes?

And yes, I know you said you've got some 4 stud wheels you want to keep, but that's a different problem. What are you running for front wheels?

Edited by GTSBoy

ummm any given brake set up? Ok... Im asking the question if these are good to use as I want to better my rear brakes, no need to be narky mate, im greatful for the help though... And my 1st question was what rotors can I use with the 4 stud gts rear hand brake set up, if 32 turbo rotors will fit, thats exactly what ill do as I have done that with the fronts... But I didnt want to go ahead and order them if they were going to turn out to deep like the ones iv just tried

Cheers

I wasn't being narky.

Have you looked at the DBA site's disc catalogue to see how compatible the R32 NA and turbo discs are (in terms of how they connect to the hub, hat depth, the size of the handbrake surface inside, as much as anything else, and ignoring the 5 stud/4stud thing)?

looked at r33 gts brakes? The non turbo r33 front brakes are basically the same size as the turbo r32 brakes so i'd imagine the 33 non turbo rears would be a good option, plus they're already 4 stud

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
