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

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
