<e36> M3 Suspension Upgrade Questions

[Mike Schaublin <mschaublin@xxxxxxxxx>]

     Hello fellow digesters,
     
     I want to improve the suspension on my '94 325i.  I have seen some 
     posts referring to upgrading to an M3 suspension.  What components 
     are involved in the swap?  I have read that the springs are not 
     interchangeable between a 325 and M3 due to different diameters, I 
     think.  Could someone please enlighten me about this upgrade?  
     
     On a completely unrelated note, what doe the letters "YMMV" at the 
     end of messages endorsing a product or service stand for?  
     
     Thanks,
     
     Mike Schaublin
