Questions & Answers
Q) What features does the Racefab have that will enhance it's performance?
A) *Relocating the driver rearward not only improves safety, but also gives a better weight distribution, this means better handling.
*The wider (72") width gives greater stability in the corners.
*Getting the drivers feet out of the way allowed Racefab to increase the length of the control arms by 30% to a centerline to centerline length of 29 1/2". The increased length means less angular change for a given chassis movement resulting in increased consistency in roll center location and swing axle length, better handling.
*Racefab's front upright design allow low kingpin angle while still achieving zero scrub radius and zero castor radius. With this design the tire tread surface is not dragged or scrubbed across the track surface, but is pivoted at the tire center as one would expect. The tires grip better, last longer and a softer tire can be used than a car with this.
*Rising rate suspension allows a softer spring rate without bottoming. this gives a softer more subtle ride not affected by track imperfections as much.
*The semi-monocoque chassis design is as much as 10 times stiffer than a space frame. This results in a chassis that doesn't twist back and forth as the suspension loading changes. This reduces chassis fatigue, maintains corner weight settings and keeps suspension points in their proper perspective in relation to one another while dynamic load.
*The 100" wheelbase gives high-speed stability and provides an optimal 1.6 - 1 wheelbase to track width ratio.
*The bodies low drag shape with it's aluminum panels are a case of modern aerodynamics meeting old world craftsmanship allowing this finely crafted car to slice through the air with adjustable wings fore & aft to balance the car to achieve the perfect setup.
*Low polar moment of inertia. The weight is located between the tires. This makes the car easy to drive and regain control when finding oneself out of shape.
*Central mounted fuel cell lessens effects of diminishing fuel weight on the handling of the car.
