LSD and 4.1 final Drive

i couldn't afford the expensive aftermarket LSD for 325i E30 so i decided to get a 2nd hand factory LSD from other BMW Diff... after all its better than no LSD at all...

pick it up for $400AUD shipped...

also i got the 4.1 final drive.... its the cheapest way to get more performance over the stock dying engine... i got it for $250AUD shipped...


here are my rough 'oh so un-leet' calculation using the gear calculator to predicts the max speed differences every gear after the final drive been replaced...
