BM WORLD 1286 Report post Posted April 1, 2012 a well set up medium case e30 diff should be ok , from a 323i 325i 325e etc. just buy a complete rear end like this. http://www.trademe.co.nz/Browse/Listing.aspx?id=460937832 but if you wanna go to the large case 8 bolt diff then i think some people do it , if you have 400+ hp etc otherwise the medium size one will do Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2136 Report post Posted April 1, 2012 (edited) yep you dont NEED the full subframe if your swapping diff sizes though, as the rear subframes are the same between all E30s. just make sure you get all the mounting bolts when you buy one. a medium case will be fine for your application Edited April 1, 2012 by _Ethrty-Andy_ Quote Share this post Link to post Share on other sites
