Welcome to the Zone mate 
A 3.91lsd is probobly your best bet,you will be very lucky to find a 4.1lsd(same ratio as you have now i think ?).
You will lose a tiny bit of acceleration due the 3.91 making the gearing slightly longer.
They arnt cheap though 200-250 ish seems to be the going rate on here.

Im hopefully sticking an is lump in mine soon, and want an LSD as well. Seeing as the 4:10's are like rocking horse sh*t, is the 3:91 that much slower? Ill be on 205/55/15's so their small wheels compared to say alpina reps etc.

Sounds like a good excuse to go to 205/50 when you get your next set of tyres!SwirlyE30 wrote:Im hopefully sticking an is lump in mine soon, and want an LSD as well.

It's not going to make a huuuge difference though, & it'll be that li'l bit better on economy / motorway RPM too...E30 in need of wiring loom smoke since April '11...
