Lots of folks run locked diffs--usually welded because that is the least expensive option--with FWD cars in IT.

Lots also run some kind of limited slip.

Locked diffs work extremely well with FWD but can be a bit tricky under hard braking and in the wet, but it is an aquired taste.

I even think someone had a "spool" for sale for a VW application.

Locked diffs require a lot of manuevering room in the paddock since you cannot make low speed tight turns very easily without risk to your CV joints.

Have fun!
