How do I make my Escudo go fast?

[King Cow]

I recently bought a Suzuki Escudo Pikes Peak Version. Apparently It's a really really fast car. But I can't seem to make it go any faster than 285mph. The final gear ratio is all the way at wide, my ride height is at a minimum and I have all the best parts.
How do i adjust the other gear ratios to give this car it's optimum speed? I can't figure out what the other gear ratios (besides the final) do. Can anyone help?

If you REALLY want the Escudo to go fast, you should try stepping on the gas!!
