Ok, so i needed a new shim kit for my r33. Ive got the 4 pot calipers on the front, searched for a part number, 41080-21U25 is apparently the one i need.

This, according to quite a few people, is 41080-21U25:

So i went to my nissan store, forked over a large amount of cash for that part number. Except when i got it, it looked different.

I scoured the internet again, rechecked the part number, and its definitly the one from what i can tell. It says that number on the packet I got.

Is it possible nissan can stuff it up? It came in one pack.

Id just like some confirmation. Any help would be appreicated!

It was $170 off the top of my head.

Oh really? Whats I find very weird though is that the outer shim (the silver part) doesn't cover the whole piston. It gets about half of it to 3/4.

The ones in the other pic i posted first look like the correct shape, they would cover both pistons completely.

The kit in the first post looks the same as the R32 GTR (sumitomo calipers) and IIRC the 33 gtst calipers use the same pad. The shims match the profile of the pad backing plate. So what you got doesnt looks right - but i checked the part in FAST and it came back with the same part number....weird.

Is this what your looking for? http://www.frsport.c...re_p_12970.html

Yeah i saw these originally, and they look like the exploded view of the r33 brake, but yeah, it said 300zx so i thought id be safe and go through nissan.

Yeah doesnt quite look right to me either, from a design standpoint im struggling to see why only half of the pistons are covered. Yeah its definitely the part number, although its weird cos on the exploded view they definitely match the pad backing plate. Dont look like the ones i got.

When I took off my shims, the silver ones only covered about 75% of my black metal ones =S

This is off a stock r33 gtst. Here is a pic

Yeah? Maybe it is correct then. Just seems a little weird it only covers half the calipers, not to mention its not even even, it covers different amounts of both pistons :S

This is confusing.

Mine had diagonally cut silver pieces too (R33 GTS-t brakes), apparently this plate profile helps with vibrations somehow, I've seen exactly same thing done to STI and some euro cars' backplates, so your kit is the correct one

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
