Ratio is different but the actual physical container of it is the same.

Was under the car today and noticed the differential carrier cover cooling fin design was different than many of the one's pictured in this thread with the Rapid Designs' brace installed (Image 1). Found it interesting and thought I'd share. My car is '25 Model Year 6MT Supra (12/24 Production Date). The design on my vehicle (Image 2), looks similar if not the same as the Z4/Supra FE design reported on post #241 (Image 3).

@rwense I'm sure you're well aware of these nuances but want to highlight for those in the same boat.

Yes, Some 25/26 Supras get the BMW M-lite diff cover with less cooling vanes because of the needed clearance with the FE/Z4 underbracing.

Re-torqued everything and paint marked it. the louder clunk i was hearing in low speed and when switching between reverse and drive remained the same. So i assume it’s normal NVH that comes with having a brace 🫡.

Man I wish my OCD would let me live without thinking the world is ending with any slight change or off sounding thing hahaha

Appreciate everyone chipping in and giving me more knowledge on this stuff.

FWIW I think it's a good thing when people notice changes or noises in their cars. It means you care, and that you're not an idiot. At least certainly not an idiot in the way some people think everything is fine right before a wheel falls off on the highway or their engine won't stop knocking.

Forgot to post this, did a diff oil change yesterday and am happy to report the brace did not slow me down one bit. 🫡

Have you tried increasing the volume of your music? Or playing something a little heavier like metallica or system of a down? That's how I usually solve unsolved noises.
