According to all the manuals I have they all run the same ratios although the 90 axles I have fitted on the 90 do have different half shaft covers.
I plan to fit a pair a rangie axles I have to give discs on the back and smaller hubs so I can fit the centre caps to my new boost alloys 8)
I am hoping the 90 callipers fit the rangie axles on the fron or I may have to remake brake set up ! :?
All coil Land Rovers are 3.54 diffs, according to Muddy web.
If your allous don't fit the hubs you have, I suspect yo may have 200TDi Defenders parts, be careful as these are not suitable for alloys. Go on, aslk me how I know :roll:
90 callipers and RRC callipers are basically the same casting, machines differently for single or dual circuit. The V8 CSW had bigger callipers on RRC vented disks, if you get the chance :D
