is this factory? or does anyone recognize it?
This should probably be in the newbies section but I figured there's more traffic here, so..
I put my car up on the hoist for a look around and found this big red brace that seems to tie the diff to the back of the transmission. It's cracked through at the back (a little hard to see). Is this a factory brace that's been painted a funky colour? or is it an aftermarket thing? I did an image search for "fd3s diff brace" but didn't come up with anything that looked like it. I guess I will weld it up where it sits. Trying not to think about what else might have been damaged by whatever was strong enough to crack this brace!

thanks for that. I just googled "mazdaspeed power plant frame" and confirmed that I've got the little placard up there too, so it's a genuine unit... didn't stop it cracking though haha!

That looks like fatigue cracking. Crack could have been started/caused by wheel hop - notorious for causing differential and other damage on FD's. Search for threads on wheel hop.
