ONLY FOR 991.1 GT3RS with our Swan Neck Rear Wing. Adding this to a car with stock rear wing will make the car unstable due to too much front downforce. Add much needed front downforce to your GT3RS. Designed to complement the 991 GT3RS Swan Neck Wing Package.
Yes we know a 991.2 GT3RS is pictured. Get a free Tshirt if you get us a picture of your 991.1 GT3RS with our splitter!
Our Carbon Splitter adds the front downforce needed to really take advantage of the Valkyrie Swan Neck Rear Wing.
With the Splitter added to a 991.2 GT3RS running our Dual dive planes and Valkyrie wing a total of
885lbs of downforce at 120mph, a 550lb increase over the car stock is easily achieved
