guitarguy: no, the fairing behind the wheel wasn't tested. (Meaning there's room for further gains
)
Topher: You wouldn't be able to just add a Kammback + boat tail combo on a Metro and predict a ~20% improvement (Kammback was ~4.9 %)
All the other aero stuff I've done upstream affects the performance of the tail - meaning it wouldn't work as well without these:
- partial grille block,
- headlight gaps sealed
- hood/bumper gap closed
- pass mirror delete,
- partial cowl block,
- wipers were off
- smooth wheel covers
- rear fender skirts
- and the big one: full smooth undertray
- EDIT: forgot radio antenna delete
