Sorry but can I add a question to someone elses thread?
Photos below from my car which is a 2018 GT with MT82 (Australian spec - so a mix of PP1 and Premium I believe) with magneride.
Reading your info above it suggests that with the Iron housing, aluminium cover and temp sensor (which it has all 3) it should be a 3.73 with Torsen. I had read somewhere that the Aus Spec cars had the other LSD.
Apologies re the untidy black underseal.... I cleaned it off the sticker as best I could!
Is there any way to confirm either way?
Hey Pete,
Feel free to always jump in anywhere - the more the merrier!
Your post and the follow-ups gives us more knowledge for sure. My response was geared (no pun intended) towards the US Spec S550’s. I don’t have any available info for the exports.
It would be cool to have a definitive S550 trans/rear diff ratio FAQ sheet for the US and Export S550s, as it would surely help out many on this site. More so when folks want to upgrade (or in some cases downgrade) their rear differential ratios due to Owner use.
