Under the skin
Complete bottom up design of a challenger SCCA FB / F1000 racecar. Designed to beat the current and upcoming generation of competition at a lower price point. Incorporating technologies to maximize driver safety and to minimize crash damage to critical components like the uprights. Interchangeability and commonality of components followed closely performance, safety and accessibility as the main design drivers. Advanced computer optimized suspension design along with tuned aerodynamics should provide a viable contender for the next F1000 Championship.
Front upright assembly
Front upright assembly shares numerous common components with the rear yet retains its own unique suspension geometry without compromise enabling you to carry less spares. Rotational inertia has been extensively reduced from the system to maximize engine power at the wheels.
Front wheel assembly
Design provisions were made to enable the use of two and four piston calipers, from just about any manufacturer of your choosing. Caster and Camber adjust ability is built into the system along with limited kingpin adjust ability through the upper a-arm.
Rear Suspension
Exceptional care was taken in the rear suspension design to make sure power is delivered to the ground effectively. A-arm length was maximized to minimize scrub yet still achieve solid camber gain in cornering. Rear bell crank location is as close to the CG as possible, at the stiffest part of the rear frame.
Side impact safety
Exceptional care was taken when designing for safety. Side impact safety has been dramatically improved over many Chromoly steel tube chassis designs through effective use of triangulation for side impact absorption, which also ads to the chassis tremendous structural rigidity at a car weight of under 800lb.
Common upright design
Despite the uncompromising front and rear suspension geometry, a common upright design was made possible through the use of clever engineering. The design minimizes weight and incidental crash damage to the upright yet remains very stiff to make sure your wheels point where you want them to. Mounting provisions were also added for cooling ducts.
Common bell crank design
Common front and rear billet bell crank design reduces manufacturing costs, enabling us to pass on the saving to you and enabling you to carry less spare parts. Design was engineered to be extremely stiff to make sure your dampers and springs inputs are effectively transferred down to the tire.
Common camber block design
Universal camber block design allows for two things: Enables a common upright design along with almost unlimited suspension adjustability and minimizing the number of spare parts you have to carry.
Small rear cross-section
Aerodynamics played a major role in the layout the chassis. Great care was taken to minimize the rear cross-sectional area (the hole that the car leaves in the air) and to maximize space for sculpted diffuser.
Multi-engine installation
The ability to use engines from any manufacturer was of prime importance. We recognize individual driver’s preference for an engine brand, as each engine has its own personality. As a result we designed in provisions to mount any of the four Japanese engines, Honda, Suzuki, Yamaha, Kawasaki and even Hyabusa.
