981/718 GT4 Renntechnik Extended Wing Risers

981/718 GT4 Renntechnik Extended Wing Risers

Taking design cues from the 991 generation GT3RS, our wing risers improve aerodynamics, aesthetics and interior rear-view mirror visibility. The rear end of the GT4 is enhanced beautifully with an aggressive, yet purposeful stance. Despite being a stunning car from the factory, the stock car lacks some of the aggression of other GT and RS Porsches - our wing risers address this by raising the rear wing by 3" on a deeper and stronger riser, which also allows the wing to flow in cleaner airflow, adding downforce. The result is the look that these cars should have had from the factory.


Renntechnik Extended Wing Risers and matching base plates have been expertly developed then milled from 6082-T6 billet aluminium, making them the strongest GT4 wing risers available worldwide. Finally, they are finished in a stealthy Satin Black or optional Satin Silver finish (2 week lead time). Custom colours are also available.


All Renntechnik Extended Wing Risers benefit from using your stock hardware, meaning that fitting/removal of the risers is very simple and no permanent modifications are required. A detailed installation guide is included.


Compatible with the following models:

981 GT4 & GT4 Clubsport

718 GT4 & GT4 Clubsport.
