Differential Mount
Hello s2ki,
I was wondering which oem differential mounts i needed for replacement due to mine being almost completely shot? I noticed that a few sites indicated that I needed Qty 2 of the right side (passenger) and only Qty 1 of the left side (drivers). Is this correct or did someone mess up the correct Qty required for the sites?

There's two small mounts in the front two larger ones in the back. It's usually the driver's side that goes, the front ones rarely go bad, get all 4 if you want to be anal about it. Otherwise just fix whatever's broken.

Yes.

Or... dare I say it, get Innovative or Hasport mount kits (comes with 4 mounts total, 2 front and 2 rear). Comes with everything you need. Of course it depends on how much you want to spend and if you desire a harder durometer mount. I figure if one goes out, the rest are probably tired as well. Just replaced mine with Innovative 65A mounts and they feel like stock.

I would go innovative or else you will end up with another broken mount again. When I replaced my broken diff mounts with 75A innovative mounts I didn't notice much more noise.

Oem mounts last if you rev match your downshifts.

Mount a camera looking at the rear mounts and watch what happens when you do a nice heel and toe downshift vs just slamming it into a lower gear and letting off the clutch. Downshifting is hard on the drivetrain in general, upshifting is different because when you up shift the engine speed drops, and by taking your foot off the gas you're essentially rev-matching the next gear. Downshifting you have to blip the throttle. Plus just think about it logically, how much more composed and smooth the car rides when you do a proper downshift vs just dumping a lower gear.
*To simply answer your question the differential twists along with the drive shaft. Since the drive shaft turns counter clockwise when looking at it from the back. Any twisting motion is going to be absorbed mainly by the driver side diff mount under downshifting when the shaft is turning but being resisted by an opposite and sudden force caused by engine breaking.
By rev-matching your downshifts, you prevent this sudden loading. Of all the S2000's I've seen with busted mounts almost all of them had a leaking driver's side mount. The passenger side ones barely even get worn.
