FD rear end
Ok FD guys, i searched but couldnt find a definitive answer.
Are ALL the rear diffs the same on the US 93-95 cars? Did they all come with the torsen LSD carrier? Regardless of transmission or trim?
Further, did they ever make a change to it between the 3 years of US FDs?
I wanna buy a torsen for my TII FC, so i need to know if i can take any diff from any US 3rd gen car. Im not planning on using the FD ring and pinion because I like the 4.10 gears. I might even buy 4.30 gears.

Higher power/single turbo FD guys tend to go for a different diff setup b/c they stock torsen has been known to break on the street during a hard shift with power levels of above 400 rwhp or so. As much as I loved my stock diff, I ended up having a cryoed S4 TII diff installed along with the RZ 4.3 gears. For the street I'm very happy with the change, I'll post up my experience next time I get on the road course

Well mine is an S5, so it is currently the viscous. It still works ok but ideally i want a helical.
I do absolutly no launching or straigh line drag. All roadcourse and street driving.
Also My car will not ever produce close to 400 HP. I will be a little over 300 at most. I will always be using a sprung clutch so I dont expect to shock load the rear end abusivly.

The Kaaz can be noisy if you don't use the proper fluid/friction modifiers.
I destroyed my Torsen from an over-rev drag launch (almost stock engine). Since I don't drag race anymore, I kinda wish I still had a Torsen. It's quieter and smoother-engaging.

The axle stubs are different lengths in the S5, where the FD (and S4) have symmetrical stubs.
