Lower Spoilers / Trays / Corner trims
Kit includes 1 x Adaptor kit and 1 x 991.1 front lip spoiler
Fits:
Porsche 718 Boxster / S / T- 2017 to 2024
Porsche 718 Cayman / S / T - 2017 to 2024
The OEM front lip spoiler solution for the Porsche 718 Boxster / Cayman with standard bumpers.
A properly integrated and quality solution for your Porsche using the newer generation 991.1 OEM Porsche sports spoiler and a purpose built adapter kit to achieve compatibility with 718 Porsche models (2017-24)
Benefits of the 991 OEM Spoiler?
It creates a front-end aerodynamic profile similar to newer models and provides more usability than wrap-around spoilers due to increased ground clearance at the corners. It’s an original Porsche part that looks great and provides a refreshing update to the 987 Boxster front end.
How our adapter kit works:
991 Spoiler mounting points are not compatible with the 718 Boxster / Cayman so the kit solves this problem with a unique set of adapters that:
- are strong, secure and will not damage your bumper in cases of spoiler scraping or impacts
- eliminate the risk of damaging components (such as headlight washer lines) inside the bumper
- are both re-usable and reversible
Installation:
Almost zero DIY skills are needed
Step by step instructions provided
30 - 60 minutes of quality time with your 911 depending on the kit
No need to remove the bumper
A jack or ramps to raise the front of the car makes installation very simple
