Right if you don't change it the pedal stroke is reduced, making the pedal either never go as far down as it should, or it will sit much lower to the floor at rest. You will still fully travel the master cylinder. My main point is it's not anything like the OE pedal stroke and I don't think you'll like it. With the modification, its very hard to tell mine from a mechanical clutch linkage other than its a little lighter and smoother.
