E36 diff and axles

[7ishNZ]

I have gone with the nissan rear end. The silvia S13/14 diff has a 3.5 ratio as an option,wth 4.083, 4.1 and 4.3 commonly available. The lsd's cost about $100. There is also a number of different axle lengths....
A trip to the local BMW wrecker showed that there are very few different ratios available in NZ, and the lsd's go for about $1000!!! Nissan it is.....
