UK turbo's have a 3.6 rear diff (due to the 1.1 drop gears).....................
certain early WRX's have a 3.9 rear though not many, and the sport N/A version uses them.............

the uk rear diffs are the now 3,6 or 3,9 ?
is it a straight throw change ?
and how about the JDM 6 Speeds R180 ? Does it fits my STI Version II directly?

David is of course right.
UK boxes have the 1:1.1 drop ratio on the back of the boxes, and the Jap imports it is 1:1.
The UK's are 3.6.
The 3.9 R180 diffs will not fit directly into a R160 car without the matching half shafts and hubs/brakes.

so i can use the UK Rear Diff on my STI Version 2 with the stock Gearbox and Driveshaft / Half Shafts?
with the 3.6 diff its possible than drive more than 260 kph @ 7T RPM ... so thats 30 kph more than with the stock one... that will be enough for the first time
how much slowlier i will be from 0-60 MpH with that Rear Diff? Any ideas?
whats years fits my car? 1993-2000 ?
