I just did a good throttle-stop testing session. Ideal conditions - 13 degrees C, no wind, 30 per cent throttle. To give some idea of the consistency that is achievable, I did three tests of the car in its standard configuration (ie with undertrays and rear wing). One at the beginning, one at the middle and one at the end of the 40 minute test session. The results (km/h) were:
I am therefore using an average of 103.5 km/h as the reference.
Results of testing were:
- No rear spats - 104
- Vertical front winglets 40mm gap - 103.5
- Vertical front winglets 20mm gap - 105
- Edgarwit front air curtains 40mm gap - 106
- Edgarwit front air curtains 20mm gap - 107.5
- Rear vertical spoiler lip 35mm - 102.5
- Windows open - 101
