I've just had an engine conversion done on my 95' GTS4, but the front diff was left as the original Stagea diff which is a 4.083 ratio, and I've still got the original GTS4 rear diff which is 4.363 ratio. It runs but if you downshift gears or at low rpm has a good shudder to itself.
Can anyone suggest where I could get a 4.083 rear diff, the cars I know with these ratios are Nissan Stagea Auto and also R34 Non Turbo Automatic, S15 Non Turbo, S14 Turbo/Non Turbo Manual or S13 Turbo/Non Turbo Manual.
Pm any advice
Cheers
Dan
