Question : What bike modification has the most impact on performance?
Answer: Suspension! Suspension! Suspension!

You may be surprised to know that the answer is not extra power. The greatest gain is to be faster through the corner, not in a straight line. Improving the suspension allows you to brake later, carry more corner speed, accelerate earlier, and reach your top speed quicker.

And the best for the end

The best example is on a race track, where approximately 80% of the lap time is spent entering and exiting corners. If a bike can corner just a fraction of a second faster on every corner, 80% of the lap time must show an improvement. We've calculated, a 100 bhp 750cc bike would need to squeeze another 40-50 bhp to achieve the same gain.

Ok mate, it comes from an Hyperpro leaflet and of course they were not going to tell us that changing our suspension is useless, but anyway, I do believe in that way of thinking. And even if I think they may exagerate when they speak about 40-50 bhp, I do think bike suspensions and rider ability are more important than 10bhp (especially when those 10 bhp are out of 60...).
