RSS CarbonAero Package Test – Autohaus Hamilton Porsche GT4 – SMP 24/1/17
Introduction
A Porsche Cayman GT4 was tested at Sydney Motorsport Park with the aim to evaluate the performance of aerodynamic upgrades offered by RSS. The car was equipped with a DSC Sport damper controller, which served the purpose of a data logger. The GT4 was driven by Garth Walden (V8 Supercars / Porsche Carrera Cup Australia). Between the third and fourth sessions, the RSS CarbonAero Package was adhered to the vehicle for the purposes of testing to evaluate their effect to the vehicle’s performance.
Method
Garth was given three track sessions to familiarize himself with the car before the Aero Package was adhered to the vehicle. The first two sessions ensured that Garth was fully confident with the car’s capabilities, so that he could complete the laps as fast and as consistently as possible, and the third was analyzed, to be compared to the car after it was fitted with the Aero Package.Before the fourth session, the GT4 Aero Package was applied to the vehicle, and was then tested on the track. No other modifications or adjustments were made to the car. Data from the session was pulled from the data logger and the fastest laps of the two sessions were compared.
Results
The recorded best lap time without the Aero Package was 1:45.77. The lap time reduced to 1:45.44 with the RSS CarbonAero Package attached.
Driver’s Comments paired with In Car Video Footage and SMP GP Track Map:
1. You can feel a slight increase in drag on the straight (-1.5km/h at 215km/h or -0.93 mph at 133.6 mph)
2. Was able to Brake ~8 meters later into T1, car was more stable.
3. A significant gain in speed through the high-speed Turn 1 of (+6km/h or +3.7mph) was achieved, which is coupled with gains in entry and exit speed.
4. Gained Aero Grip – Gained Mid-Corner Speed, The GT4 is more stable in the high speed corners.
5. Was able to Brake ~8 meters later into T2
6. I can take T3 almost flat now – the car has better grip
7. Front grip improved through T4-T5, where the car previously showed understeer tendencies.
8. Was able to Brake ~5 meters later entering T6.
9. More High Speed Stability through T14 and T16.
10. More Grip Overall, 100% Throttle Achieved Earlier out of T18.
Track Map - Sydney Motorsports Park - GP Circuit
Figures 2-5 display comparisons of each damper’s travel between the two laps. Very similar trends can be observed between the two laps with a couple of points of divergence. While accelerating on the main straight, the two rear dampers experienced greater compression after the aero kit was applied. Similarly, while decelerating on the main straight, the front dampers experienced decreased compression after the aero kit was applied.
Discussion
The most significant point of divergence in the vehicle’s performance was while the vehicle was approaching top speeds, where the rear dampers experienced greater compression of approximately 3mm. This compression implies a greater down-force being applied to the vehicle over the rear of the vehicle’s body and the spoiler. This additional down-force had a small reduction on the vehicle’s top speed, a reduction of (-1.5km/h at 215km/h or -0.93 mph at 133.6 mph). A significant gain in speed through the high-speed Turn 1 of (+6km/h or +3.7mph) was achieved, which is coupled with gains in entry and exit speed as the RSS CarbonAero Package improved the car’s stability.
Conclusion
The RSS CarbonAero Package improved the lap time performance of the Cayman GT4 by 0.33s at Sydney Motorsport Park. Average lap speed was improved and driver confidence was increased.

Very, very interesting. As expected, there is more of an increase in rear downforce than front downforce. It's a little higher than I would have guessed though. 3 mm deflection would mean something like 100 pounds of extra rear down force at top speed (a little over 135 mph?).
Although dive planes are reported to reduce drag in some cases more than increase downforce, they must be giving some front downforce because the front of the car isn't lifting more than stock. If the rear downforce increased with the aero bits, then the front should actually lift more if it had the same downforce as stock, because of a see-saw effect. (not sure if I missed it in the above explanation, but FYI, greater deflection means the car is lower at that damper)
How did you datalog from the DSC controller?

Garth's flying lap comments about improved front grip, reduced understeer, visible steering input (video) and damper data would support your observation that the Canards do generate downforce, reduce front end lift at speed and essentially balance or counter the see-saw effect generated by the increased rear downforce from Main Wing Extension and DuckTail Extension.
