Kit includes Sneed4Speed splitter and Sneed4Speed carbon rear wing. All hardware is included. Fully adjustable race front splitter with integrated under tray, allows adjustment of front down force for driver and track needs. This splitter is specifically designed for the 335 front bumper to provide max down force, reduce drag and improve engine power. The integrated under tray provides engine compartment air scavenging for higher down force and reduced engine compartment temperatures. Also, creating more power and reducing drag over the factory setup resulting in higher top speeds. The tray creates a skid plate under the front of the car, protecting the radiator and front of engine from debris. Extra wide splitter design smoothes air flow at front tire to farther reduce drag. Splitter attaches with fully adjustable super-duty aircraft grade aluminum stanchions, aluminum and steel brackets and heavy duty fasteners. Splitters now carry a full 100% replacement for life with the original purchaser (doesn't include hardware or stanchions). Fully adjustable carbon fiber rear wing for 335 is designed to produce high down force, low drag, and increased tire grip, resulting a lower lap times. Wind tunnel tested 3D design uses 2 different planes of aero foils to increase down force by optimally using the air moving over the roof and down the sides of the car.. The wing produces 200lbs of down force over stock trunk lid at 100mph with drag equal to less than 1 side mirror. Mounts and stanchions are designed to position the wing for most efficient use of air over and around the car while providing positive and consistent downward push to the tires. Best results are found between 2 and 6 degrees angle of attack. All mounting hardware is included for installation. Specs: 63" wide carbon fiber wing Downforce Adjustable Aluminum mounts Weight 8 lb total with mounting hardware. Now available with black wing mounts and black splitter stanchions!Sneed4Speed
