Yeah, the diff was awesome in my corrado, could really put the power down in the corners and it just gripped and gripped and pulled the car round. When it finally did let go though it was a bit scary as both wheels were breaking loose instead of just spinning an inside one.
I reckon changing the final drive would make a massive difference to this car. Its the first car ive ever had where I actually use first gear a lot, and going to 65 or whatever in 2nd is stupid in a 2.0 16v.
