S at the start indicates it as an LSD so looks like you have one

nice 1 guys is the 3.64 of the sport? whats the best ratio to have? im still tryin to suss diffs out. well chuffed theres 1 on it tho.

As far as I'm concerned, a 3.64 is the ideal diff. for a 325, but I wouldn't want one on a 316.
The actual 'working' life of a clutch type LSD is just a few hours, so the chances are yours could do with a rebuild, if it hasn't already had a relatively recent one.

oh i didnt know that. is it a easy job to rebuild ?

Needs specialist knowledge and equipment.
Contact 'Gareth', one of my fellow team members on here. He rebuilds them at a good price, and can uprate them from 25% to 40% (IIRC), if required.

he can also uprate to 70% and his prices are better than fair!
