Reducing drag at high speed? Well, to reduce drag the most, you would have to:
1. lower your car as much as possible
2. make the undercarriage completely flat, i.e. cover everything you can with completely flat panels
3. use the touring/sport rear hatch spoiler, as it further reduces the factory drag coefficient from 0.30cd to 0.29cd.

But all of the above are really just percentage or two improvements....you're not going to be able to attain significantly higher top speed, nor improve mileage. You're better off putting thinner tyres that you'd pump super hard, in order to reduce rolling resistance, but that leaves you with a shitty ride and bad handling. If you're pursuing top speed, you'd rather get more hrsprs. If you want better fuel efficiency, maybe get a different car.
