I just know Lugod as oinojo here on the forums. My searching for him found him on LinkedIn of all places.

This is super helpful. Thanks!

Yeah I was never a big FB user, but I do use it for car groups. S2k groups including the one I mentioned mainly. Otherwise it is mostly trash in the feed

Update. Found my problem...





So, not a diff fluid issue.
Not wheel bearings.
Not axles.

Pinion toast.
OEM torsen is also trashed given that I had whatever came off of this turn into liquid molten metal and helped itself in "lubricating" the OEM torsen.

Ring and pinion are super hard to source, whether stock or aftermarket. No OEM units available from Honda state side. Is also a questionable long lead ordering from Japan.

After market units - called multiple vendors (Evasive, ASMotorsports, Formula-S, Kami Speed, GoTuning/Spoon Sports USA, Rockstar Garage, Jesse Streeter, and a few others I can't remember). Ended up with Spoon 4.44 from GoTuning/Spoon Sports USA - local to me - 15 miles away.

New differential (OTS OSG unit with 4.44 Spoon Final Drive) feels awesome, just from driving on the streets. Can't wait for the next track day. Car wants to rotate a lot more while on throttle but in a very progressive and predictable way that you can very smoothly feel, when compared to the OEM torsen (then again, my OEM unit could have been progressively getting worse). Happy with the shorter gearing feel just from driving on the streets. I'm running 265/35r18, so slightly taller than the 255/40r17 that i've been running for the last 14yrs. Glad that OEM ring and pinion was unavailable. That said, will need to learn the new diff characteristics on track and adjust to different shift points and likely holding different gears through some turns. Gonna be fun re-learning things.

Is your car turbocharged? Maybe spinning wheels that "caught" on a sticky surface?

Thanks!

NA with OEM tune. Just a testpipe and snorkel on OEM airbox. Basic track setup - 255 square on 17x9.5 with 200TW tires and basic wing/splitter package - just recently upgraded to 265 square on 18x10.5 but didn't get to really test it out, diff was toast in the first session.

Lots of wear and tear over the years - i do take a lot of curbing. Some old track footage from a few years back, haven't posted much footage lately - too busy with the kids (i'm just happy to get some time to drive).

So. Shorter gears feel nice - took it for a canyon drive along Ortega Highway.

That said, speedometer is off. At 80mph per phone GPS, my speedo shows 85mph. How do I fix this while keeping my stock ECU? I'm still on the OEM tune and plan to keep it that way - I believe it's the best way to go for longevity, reliability.
