Rear diff ratio
Hi,
I have a WRX STI RA 1995, and I need to know what ratio the rear diff is.
I am going to fit a gearbox with a 4 to1 ratio but I am not sure if the rear diff will be the same ratio.
Any info would be great.
Cheers,
Andy.

Most early RA's were 3.9:1 ratio. You'd need to tell me the TY number off the gearbox or chassis plate. 'Box is safer as it is going to be correct. There is a white label on the clutch housing close to the starter, it'll be TY752 Vb ???
Unfortunately my ratios list is at the office and l cannot confirm until Monday - will that do??
