Rear Diff options and opinions

[Lsxphil]

Hi Guys, i am working on the rear of my car at the moment, i want to run a stock LS3 motor, whats the best rear diff ?
i am told by a guy who has the same engine he had a modified m3 diff which dyno torque fitted what are the oprions?, i have a standard auto diff and refurbised drive shafts are these any good?

I'm assuming you are aware of the 8.8 Ford option with Ronin cradle and DSS driveshafts?

I've got the Cobra 3.55 with Samberg/DSS kit and Torsen T2R. Justin is no longer supporting the RX7 community though.

Stock LS3 can break the RX7 diff and the ratio must be awful. For the road, going even lower than 3.55 would probably be better, but depends on your gearbox ratio. I'm running the 2010 Camaro TR6060 (inc LS3).

I will be running the TR6060 also but want a tough unit diff wise.

If you find someone or somewhere, let me know as I've only been able to find them in the states and the explorers sold over here seem to be the earlier ones.
