I am looking at a caliper upgrade for S13, and was looking for r33 gtst calipers.

after much searching, I have noticed that Z32 are of similar quality.

Visibly, is the ribbing on the Z32 the main difference?

The r33 calipers only come smooth, yeah?

any other things I should note? I understand they are both sumitomos...

Would there be a price difference with the two, or would I be looking at paying the same?

Cheers,

Beau

edit: I'm also assuming that r33 gts calipers aren't even worth a mention?! Do they look similar at all? They aren't sumitomo... correct?

The R32 GTSt, R33 GTs25T and Z32 calipers are all 4 pot with the same sized pistons. They are all alloy, unlike the S14/15 calipers etc. The ain difference is the R32 and Z32 are deisgned to work with a 280mm rotor. You want to run the Z/R32 caliper then you need to buy the 280mm rotor.

The R33 GTS25t caliper is designed to work with a 296mm rotor. much like the R32 GTR caliper. So if you are going to use the R32 GTR or R33 GTS25t caliper then you need to use the 296mm rotors. The 296mm rotors and R32GTR or R33 GTS25t caliper would be the pick of th elitter for an S13. They do cost more.

Another alternative is to run the Z32/ R32 caliper with an adaptor and use the R33/34 GTR 324mm rotor. Its a budget fix and means you have to run 17" wheels. But its another alternative.

Personally i would grab R33 GTS25T calipers and rotors

OK... very helpful, thank you!

My cousin (that I am sourcing these for) is under the impression that the 33 calipers can be used on the s13 rotors.

I would have thought that you'd need the 33 rotors too, as you have suggested, and just redrill them to 4stud.

Can the 33 calipers be used directly on the s13 rotors?

Cheers,

Beau

      Agree with Rob. I recently did mine and replacing with a brand new unit made the most sense compared with rebuilding my existing gearbox.

      Rb25 trigger kit and timing misalignment

      By GTSBoy · Posted

      Are you suggesting that the kit did a cheap and nasty job of just jamming the wheel in between other things and caused the misalignment? I mean, we normally do this with an integrated crank trigger wheel, not something bodged on. It's not 1995 any more.

      R-chassis INNER tie rod torque spec?

      By joshuaho96 · Posted

      I mean, given the number of BMWs you own their tolerance for improper torque is rather low. The number of torque + angle spec bolts and non-reusable bolts in one is nuts.

      Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.

      Rb25 trigger kit and timing misalignment

      By drifter17a · Posted

      Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.
