I have a 3.25 diff from my M3 and was wondering who would want/need a 3.25 ratio other than the M3?

Is it worth selling, are they sought after?

Pretty sure it's used on M50 conversions.

I'm pretty sure you're using a 3.64, how big of a difference does it make?

Along with losing all the kilos in the car :)

it's noticable shorter. I might go for a 3.73 with more lock, so need some funds

How much my 318is revs at 90 MPH (4500 rpm) on the motorway, I think I should take it for that lol.

I seem to be doing more motorway work in it right now.

3.25 is the one to have for the m50/52 conversions if using the matching non-overdrive gearbox ie 5th = 1:1 I believe.

thanks for the info. I am tempted to stick it on EBAY or the for sale section.

UweM3 I think they are worth more than your 'standard' LSD. I wouldn't be too shy and put it at £300+ maybe stretch for £375 on ebay. This is all providing its pucker :)

thanks, thought about £300ish. Last time I drove it I "checked" the LSD function on wet road and it pulled just fine with both wheels. :D

I usually don't sell the original M3 bits, you never knwo when you need them. But spendings are lately a bit much, so have to find some funding...
