does * I tried to use text speak but the text speak filter stopped me * know if a 1989-G reg 325i sport automatic would have a limited slip diff as standard?

All 325i sports should have an LSD, an 89 car should have a 3.91 ratio LSD.

ok thakns for that

[hands]

if its an auto & 1989 it should have a 3:73 ratio lsd diff,all 325i sport auto diffs are 3:73 i ve had a few n all were 3:73 ...

[jon286]

so the diffs a bit lower geared in the auto? i guess if i put a manual box in it then it will rev out quicker than a manual sport

[kieron]

a 3.91 would rev quicker than a 3.73. seems like an odd way round to me, always thought autos were geared higher to aid acceleration

[B7]

they are on a standard 325. 3:64 on a manual, 3:73 on an auto.

Don't forget the US spec M3's and alot of the US spec 325i autos come with the medium case 4.10 LSD's as well.

3:91 ON THE 90 SPORT AUTO i HAD The earlier cars had 3:64/3:73 but the later ones are so slow and heavy they needed a 3:91
