diff help
hello all this is my first post and not to sure what im doing but hey will give it a go
. my friend is building a westfield kit car and would like either a 7" or 7.5" diff with 3.9 or 4.1 ratio and lsd - it has to have 100mm lobros - my mate reckons maybe an escort cosworth one ?????? any help would be great
escort/sierra cosworth are 7" with a ratio of 3.62 same as the 2.8/2.9 xr4x4
the 2wd sierra cosworth is a 7.5" diff with larger driveshafts
the 2.0L xr4x4 uses the 3.9 7" rear diff
4.4 diff havnt a clue what there used on

if it needs larger output shafts, the 2wd cosworth ones should fit!
