Stohr WF1

The WF1 is a thoroughbred prototype class sports racer.  It has secured championships in almost every year since its introduction!  Drivers like the WF1's response to their inputs and say the feel of the car at speed, is addicting. More than one driver has sold their very serious production-based race car to buy a Stohr WF-1, after just one turn behind the wheel.

WF1 Driver Doug Campbell says this: "I came from (Formula) Atlantic where it was point and shoot. It felt like cheating to be honest. My WF1 requires more input and the results are far more satisfying. The perfect lap feels like you're working in concert with the car's capabilities. The results are FA speeds with a far more visceral experience."

The WF1 has a full ground effects underbody. Choose from our unlimited P1 tunnel floor or our new P2 flat floor. The large chord carbon rear wing and adjustable flap are positioned to maximize air flow from the rear diffuser. The carbon fiber front diffuser provides matching grip and also provides crash protection. The body is available in carbon fiber or fiberglass using advanced polymer matrix composite.

A hybrid carbon fiber cockpit with steel tube front and rear clips. Cars for Indy and F1 require drivers to be surrounded by a carbon fiber survival cell. Stohr pioneered the use of this technology with this class of car.

Standard equipment includes a Momo steering wheel with SPA quick release and F1 style paddle shifter. An optional dash provides RPM, water and oil temp, oil pressure, lap times, and data recording. A Stohr designed light weight pedal assembly is adjustable for the driver.

The WF1 accommodates modern 4 cylinder "super-bike" engines including the extremely capable Suzuki Hayabusa. Standard equipment includes a WRD designed chain-drive differential with lightened CV joints and hollow halfshafts, aluminum radiator, and large oil cooler. The Stohr billet aluminum transaxle case is designed to take suspension loads while destressing the engine case.

Industry-leading Penske shocks are available in single, double, or triple adjustable models, providing an unparalleled level of control and aiding with mechanical grip. Ultra-light Jongbloed center-lock racing wheels come mounted with sticky Goodyear or Hoosier tires. Our bespoke uprights are machined from billet aluminum with durable sleeves installed for increased wheel bearing rigidity. Large wheel bearings are used to attain slower bearing speeds while withstanding the high downforce loads our cars generate.

Wilwood billet aluminum brake calipers. Custom vented brake rotors which are fully floating on light weight billet aluminum hats. Floating rotors provide a firmer pedal and longer rotor life. Master cylinders are Wilwood with cockpit adjustable brake bias control. All of this gives the driver increased confidence under braking
