Rear Diff
 

Does anybody know if a 97 wrx rear diff is the same as my uk terzo, also does anyone know what the ratio's are on the wrx and mine if different?

best way off checking mate is to take the plate off the diff.(which filler and drain bung are located in have to take diff out of car first) and crack it open should be ratios written on the main gear if you spin it and clean it up....that way you cant go wrong..shouldnt take long to get the diff out very easy if im remembering correctly!!

Cheers mate....
