Road America was a lot of fun. Surface was slick like usual since the repave.

My fastest run:
It was good seeing @AsparagusMike & @suspenceful out and about. Veggie mikes car sounds great as always and Spence’s ///m looks glorious
Those pesky S2000s
-
A dab of oversteer here and there. Did anyone spin?
Yes there were lots of spins and 6 or 7 cars broke on course. “self tech” due to the pandemic seems to be more hazardous for your health
-
What rear end are you running?
How close were you to using all of second on some of the straights?
3.25 with a ZF trans. Probably had another 700rpm to go before limiter is my guess

Shots from first event (USAIR) were posted.

Wow I'm surprised they did a self-tech. That seems sketchy...
Tire/wheel fitment is awesome, looks great!
-
Was nice seeing/talking to you there! Great driving as always. I have some work to do...
Do you know if there will be photos from this RA event?

Probably, I think Austin was at the event.

Diff stuff is all in, next autox is the 28th. Hopefully finish it in time
-
^dumbass me forgot about the orings/seals on the flanges so I ordered those as well
-
Also shots from RA were posted

Started pulling the diff, which turned into pulling the axles because I observed some weathered boots, flung grease and the axle stub bolts were coated in watery axle grease. Luckily I have enough GKN/EMPI repair kits to replace/repack every boot. It’ll be nice to check this off the list, car is getting closer to 99.9% “done”.
side note: cv grease sucks
-
Both are rebuilt and ready to go in once the diff is finished. The drivers side was near death in terms of lack of grease/grease condition, so the timing of this couldn’t have been better.

Should've waited till you were on the way back from the picnic to address this

Got around to pulling the diff out.
comes apart quickly. Thanks @B C for removing the grime from a previous life.
gutted, reassembly of the internals is exactly the opposite of disassembly, less replacing the spacer with a third friction disc & dog ear plate.
also replaced these clips that retain the axle stubs. They came with with new seals for the output flanges so why not.
^engage safety squints for those
slapped new o rings on the output flanges too for good measure. Need to find a drift/socket large enough and pop the shaft seals out and replace them as well.
slapped the carrier back together with the new discs that’s where I left off for tonight. Once I get the seals in, it is ready to get slapped back into the case. Then I can start on replacing the pinion seal. Punched/marked so I don’t screw up the preload
here are the worn out discs that gave up the ghost at 41ftlbs (breakaway tq)
-
Whats the 1-10 difficulty level on this job? Any good guides out there?
It’s easy. Just take your time and keep track of the order of the parts. Tons of good info on it as well.
these are the main ones I used. One link is a total rebuild that involves setting preload. With the replacement I did above I don’t need to mess with that.
part I was most nervous about was stripping the stock hardware on the carrier. I had an extra set of hands and they all came out without any issue. This hardware gets replaced with Thayers stuff anyways

Nearing completion
need to pop the axle stubs back off and torque the bolts, then it’s on to the pinion seal
