718 GT4 Products

Get better aero performance on your 718 GT4. One key factor the car lacks is meaningful downforce. 

Designed using Wind Tunnel Validated CFD and rigorously tested, the Dundon Complete Aero Package gives your 718 GT4 at least 4X more downforce and the driver more confidence to go faster.

Dundon collaborated with BBS on the design of these beautiful, light and very strong wheels.  These are based on the same wheels that run on the 997RSR race car!

Add major downforce and performance with our 718 GT4 carbon swan neck wing and carbon dual dive planes. This package gives big downforce and major confidence to the 718 GT4 driver!

718 GT4 Valkyrie Carbon Splitter!

Complete your Dundon GT4 Aero Package with the Valkyrie Carbon Splitter.

Our Carbon Splitter adds the front downforce needed to really take advantage of the Valkyrie Swan Neck Rear Wing.

With the 718 GT4 Splitter added to a car running our Dual dive planes and Valkyrie wing a total of 885lbs of downforce at 120mph, a MASSIVE increase over the car stock is easily achieved. 

*Car in photos is a GT4RS. The splitter is the same between both cars. Dive planes are different.*

Get your 718 GT4 Spyder GTS to sound as it should!

Gain 30 HP to the wheels , Lose Weight and get the sounds you're craving, all with a lifetime warranty!

Porsche doesn't build a GT4-RSR, but if they did, it would sound like this! Inconel... Light weight, RSR scream. Much like our renowned "Crack Pipe" for the 997-991 GT3's and Cup cars, this exhaust is not for the faint of heart. Pure sound, no valves, no rasp. Use with our OPF delete pipes for the stock headers or with our Street or Race header Packages.

We were never happy with the "paste on" wind deflectors and the other styles with plastic "guts" that just either strip out the screw hole and fly off, or debond and fly off.  

So we made the ultimate wind deflector for 718/981/991 cars.  CNC machined inner frame, pre preg Carbon outer deflector.  It's the ultimate!
