The Verus Engineering OEM Wing Riser Kit not only improves performance of the factory rear wing, but also improves visibility out the rear window of your 991 GT3. This means an increase in rear downforce and a rear view mirror that functions better then before. The units are produced in house on our 5-axis CNC mills out of 6061-T6 aluminum.
Utilizing state-of-the-art analysis software during the R&D process, we were able to ensure that the OEM wing improved performance. Using in house scan data during the design process, we were able to design the wing risers with aesthetics that follow the factory Porsche body lines and bolts on like an OEM piece.
Add performance, improved aesthetics, and function to your 991.1 or 991.2 GT3 with these simple to bolt on units.

The SportDesign package includes not only the SportDesign front apron with distinctive spoiler lip, but also a rear spoiler that emphasises the ultra-sporty look of the new 911 model range and helps to reduce lift.
If your vehicle is already equipped with the SportDesign package, there is still scope for further enhancement with the Aerokit Cup available from Porsche Tequipment.
Note: reduces ground clearance. To preserve aerodynamic stability, front and rear spoilers may not be fitted separately.

Dramatically improve rear-end grip at speed with our 300mm chord, swan neck rear wing. The wing and full aero kit were designed in CFD to greatly improve the vehicle's performance on and off the track.
The wing is a large driving force behind the improvement in downforce, coupled with the front splitter it transforms the GT3RS into a track weapon.
The rear wing was designed, iterated, and tested in CFD and a wind tunnel. All component mounting was designed off OEM scans and requires no permanent modification to the rear hatch of the vehicle.
The uprights are CNC machined from 6061-T6 aluminum and were FEA analyzed to ensure strength was kept high while weight was minimized.
