Ok so I said screw it and lightly drove it anyways
-
Looks good! A little drive just helps persuade the rubber to fit, that's all.

Still gonna run the larger spacer for peace of mind lol

We call that "self-clearancing" where I come from.

New clamp for PS gets here Monday. One day late of the autox

RT660s were great, drove pretty similar to an RE. Settled around 31 hot, which doesn’t mean much without using pyrometers but that’s where the car felt the best for me.
one issue I did have which was super frustrating was when the car would be super gripped up in a corner, the inside tire would spin up a bit. Almost felt like an open diff.
the skid plate also slammed on some corners (better than the oil pan though) which is quite the shock mid corner. Shawano is quite the “roller coaster” though so I wouldn’t expect this to be normal behavior at 90% of the events we run. If it keeps happening I’ll raise the car and get it re-aligned.

Video of my fastest run + results from morning/afternoon session. rewatching, there are definitely areas I could’ve picked up time, but that’s the way it goes lol
cant get the YouTube vid to embed for whatever reason, probably because it’s unlisted(?)

It sounds soo good
I’m really happy with the BW 3” exhaust
-
Bottoming out on the skid plate? Mine has saved me but that's skating over rumble strips and slamming onto the concrete gator teeth on track. What spring rates are you running and what's your ride height?
You can hear it in the video around 57/58 seconds. 8k/10k rates (450ish/570ish lbs)
here’s the ride height. As I mentioned it really only happens on the abrupt elevation changes at Shawano. Also I’m just assuming it’s the skid plate as nothing else is that low and I have no evidence of tires rubbing on anything or exhaust hitting
-
Hmm, not low at all. Those must be some wild elevation changes. Maybe it's the picture or my eyes that makes your front negative camber look pretty intense.
Get underneath the car and take a look for scrapes. My skidplate looks like an angry tiger went after it with claw gouges in the sheet metal. I'm at 525/700.

It’s the stupid iPhone picture. I’m like -2.9° in the front
Planned on checking the plate out, it already has a bunch of scrapes so it might be hard to discern which are Shawano related haha
-
Man, you've always had the best sounding E30's.
New wheels look great! -

Fixed, I adjusted the embedded content width to 800px from 500px. Youtube was requesting 560px haha. Car sounds great! I should really come up to Shawano and watch being its 40 min away.

Thanks Chris! Once they start allowing spectators/ride alongs I think it would be worth it.

Well, measured the breakaway torque of the diff over my lunch...ended up ordering a 3 clutch setup from Thayer Motorsport and everything I need to replace the leaky input shaft seal. Should be a fun project
-
What was the breakaway #?
40ish on a cold diff. I noticed throughout each run it would slip more and more. Based on what I could find on metric mechanic for a 2 clutch diff w/45° ramp angle in good shape It should be around 58ftlbs.
Doesn’t spec e30 cap it around 65ftlbs?

Science!
I wonder why the MM units have a lower breakaway torque though?
I've had this happen a couple times, but I just figured it was just a compromise with F/R handling bias. You could get more weight on the inside rear by removing the rear sway bar, but yeah, no thanks.
