The Top S looks more for Drift.
The Kazama looks Drag.
And the C-West is Nice but its as common on S15's as is the 400R on R33's.
The Kazama gets my vote Couldnt help but also say, See the vents on the Boot... Even better if you have a System
The Kazama also seems to be the best aerodynamic efficient for supplying air to the intercooler.
