Rennline Carbon Fiber Upkick Spoiler | Modern Performance with Classic Porsche Design
The Rennline Carbon Fiber Upkick Spoiler transforms the look and aerodynamic performance of your Porsche 986.1 Boxster with a refined OEM-plus aesthetic. Designed to deliver a modern twist on classic Porsche styling, this spoiler combines advanced aerodynamics with premium materials for both performance and visual appeal.
Fits:
Constructed from high-quality hand-laid carbon fiber and finished with a UV-protected high-gloss clear coat, the Rennline Upkick Spoiler offers lightweight strength, durability, and a perfect fit.

Whether you’re restoring your Boxster or upgrading its exterior for track or show, this spoiler enhances downforce, stability, and appearance — maintaining the perfect balance between performance and precision design.
What Does the Rennline Carbon Fiber Upkick Spoiler Do?
The Upkick Spoiler improves both aerodynamic efficiency and rear-end stability by optimising airflow across the vehicle’s body.
Core Functions:

By increasing airflow efficiency, the spoiler helps stabilise the vehicle during spirited driving or track use — enhancing grip and confidence.
Why Do Spoilers Fail or Need Replacement?
Even durable spoilers can degrade over time due to exposure to UV light, heat, and vibration.

- Fading or cracking from prolonged UV exposure.
- Damage from impact or road debris.
- Delamination of carbon fibre or resin fatigue.
- Warping or uneven fitment due to heat cycles.
- Hardware corrosion or failed mounting points.
Replacing a damaged or worn spoiler restores aerodynamic performance and maintains your car’s aesthetic integrity.
