In Reply to: So that would mean Dinan Diff "upgrade" is no.... posted by JP in TO on June 17, 2001 at 21:01:07:

The lower the ratio, the harder the engine has to work. This also puts strain on your drive shafts, clutch and differentials.

When I had to switch over my drive shaft when I upgraded my diff to 3.9 from a 3.45, the drive shaft had actually warped into an oval shape. It was no longer circular.

By putting a high diff ratio, it increases the car's torque and it allows the car to get off the mark easier. It will actually reduce your top speed, but who really travels that fast anyways?

Let me know if you want to know more.
