Aesthetically pleasing and aggressive in appearance, Canards and WING EXTENSIONS have a functional purpose with direct benefits on street and motorsports applications. Designed with the latest CAD technology, constructed to exacting standards with pre-preg 2×2 Carbon Fibre Twill, finished in a Matte Clear Coat with UV inhibitors, adhere with 3M VHB tape for easy application and removal, and are 100% Manufactured in Australia. Components are of the highest quality and are guaranteed to fit.
- Produce down force by deflecting oncoming air upward resulting in a net down force on the front and rear of the vehicle
- Can direct air towards other important aero devices or cooling vents
- Direct air away from the wheels and tires thereby reducing drag, turbulence and lift
- Can be used to balance and tune front to rear down force levels
RSS CarbonAero Package Test – Autohaus Hamilton Porsche GT4 – SMP 24/1/17
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.
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.
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:
- 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)
- Was able to Brake ~8 meters later into T1, car was more stable.
- 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.
- Gained Aero Grip – Gained Mid-Corner Speed, The GT4 is more stable in the high speed corners.
- Was able to Brake ~8 meters later into T2
- I can take T3 almost flat now – the car has better grip
- Front grip improved through T4-T5, where the car previously showed understeer tendencies.
- Was able to Brake ~5 meters later entering T6.
- More High Speed Stability through T14 and T16.
- More Grip Overall, 100% Throttle Achieved Earlier out of T18.

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.
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.
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.
