hi guys, this is my first post here, to my question, i fit 4.75 (not really sure might be 4.25) LSD Differential to my E30 323i Auto and i found out nothing happen, acceleration from stand still is poor but top end is just satisfactory. I'm a bit confused here when i check around that most of my friend request me to change to 3.75 diff. now, can you guys explain what is goin on?, i need some idea before i purchase one. What i want is to boost my speed and at the same time having a LSD axle. What original diff for my E30 323i 2door year 84
Thank you in advance!
