Upgrade for 718 GT4 & Boxster Spyder
Purchase "RS" Rear Valance With Aero Fins
  • "RS" Rear Valance With Aero Fins SKU: PKGT4RSDIF

    ★★★★★ ★★★★★ 5/5 Stars. (1 Review)
  • MSRP $1,217.60 $945.00


Rear lower bumper diffuser valance with "RS" side aero fins.  This is a direct replacement for a GT4 RS or 718 Spyder RS, but it is an upgrade for GT4 and Spyder models.  The center portion is identical to the standard GT4, but side fins are claimed to have aerodynamic benefits.  We like that this piece adds a slightly larger presence to the rear bumper, and the fins could keep some road debris away from the rear bumper paint.  

Fits 2021-2024 Cayman GT4 & Boxster Spyder models as an upgrade.  Must reuse bumper hardware and other parts from your existing diffuser panel.

Simple and Visual Upgrade for 718 Spyder
(Washington) | December 28th, 2023
For all intents and purposes, the upgrade is essentially plug-and-play. Surprisingly, the retractable spoiler, tail lights, and bumper were easy to remove - simply undo some screws/bolts and disconnect some wire harnesses. Removing the diffuser from the bumper required patience - there were several stubborn tabs to remove and because you only get the valence, you have to disassemble the diffuser as well. Once again, this part required patience as there were several tabs and pieces that make up the diffuser that must be disassembled in order to reassemble with the new valence and fins. The rear valence that comes in the kit comes with pre-drilled holes and screws along with the fins to assemble with. The fit and finish is typical Porsche quality. Simply reassemble the diffuser, assemble into the bumper (use patience) and screw/bolt/click everything back into place. I did this without a lift and took about four hours from start to finish. I did this as an aesthetic enhancement - I believe the fins finish off the diffuser and provide a muscular, but elegant and finished look to the rear end. You can also argue that the fins will save your paint from being chipped or scared from the rear tires kicking up debris into the bumper.
