Another diff question

[JF008]

on a e36 m50b25 & gearbox swap is 3.15 lsd the absolute most fantastic diff, what else could be considered.

I can have one for about £540, is it worth it or a £100 open diff would do for a road car? I don't know or understand much about the matter tbh

cheers

You could use anything from a 2.93 to a 3.46. I expect the 3.46 to be a bit busy for a road car though, especially if you do motorway miles - it could be fun round town though
An open diff is fine for road use, most cars have these, the LSD is useful if you like spirited driving and leaving 2 black lines on the exit of corners etc


What LSD would you be buying for £540?

[JF008]

an m3 one..

spirited is the word

[jmc330i]

Have a look for a Z3M LSD, they're 3.15 ratio and should be cheaper than an M3 diff and most likely less abused.

Most E30 M3s run a 3.25 LSD, but there were some with a 3.15s. Anything E30 M3 related seems to warrant high prices!

my mistake its 3.25 and comes at £475... its probably a rip off and a beaten piece of caca, it will blend in with the rest of the car very well

thanks for your help!

When the back plate it off how can you tell if the parts are worn beyond reason?
