ou just drive your 512TR or TR on the road it will probably be good for 100,000 miles. I'm racing mine so i subject it to pretty horrendous abuse. My 512TR is at or on its way to redline most of its life. I think she likes it that way too :-)

is it better to change it now, or wait for it to explode? How much damage is made if it explodes, ie: will it take out more components than just replacing the diff with an M diff?

William, it's completely changed in how the diff plates housing is manufactured...the old housings were welded and would crack at the welded seem and explode....the M housings are thicker and not welded at the stress joint like the early versions..and cannot explode like the early versions. Bigger, Better, Stronger = M

William. Contact Modena Engineering in Aulstralia
I installed one of there racing diffs in a customers TR. The part is very well machined and extremly well made. Though a bit pricey, you will never have to replace it again. Did your diff explode on you aswell?

Ive heard that most rebuilt 512TR transmissions now come with 512M differentials. What is the difference ? Is the 512M diff noticably stronger than the 512TR diff ? Thanks
