Driver skill and cost containment is the focal point.
The Formula SCCA (FSCCA) and the Sports Racer SCCA (SRSCCA) are the same car
under the skin, with the differences between the two versions being in the bodywork
and the wings. Some of the body panels are common to both versions, as can be
seen in the photos with the body removed where the panels are red (note that the
nose box, shock cover panel, and tail are not common). This bodywork flexibility
allows the car to be run in FSCCA or in C Sports Racer in the SCCA, or as a Lites
3 car in the IMSA ALMS Pro Support Series.
The engine is a sealed 2.3-liter Mazda 4 cylinder with twin cams, 16 valves,
aluminum head and block, and electronic fuel injection, producing approximately
178 horsepower. Engine rebuilds can only be performed by SCCA Enterprises, which
ensures that every engine leaving their shop is within a 3-horsepower window;
this guarantees a true “driver’s class”, where skill behind
the wheel is more important than the latest engine tweaks. The transmission is
an Elite 5-speed cable-operated sequential-shift transaxle with one set of gear
ratios; owner maintenance of the assembly is allowed. The clutch is a 5.5”
twin-disc unit with a concentric hydraulic slave cylinder.
The suspension uses pushrod-actuated springs and shocks, with
an adjustable front swaybar and fixed rear swaybar. The four shock absorbers are
sealed, non-adjustable Bilstein gas units; a switch to Penske rebound-adjustable
shocks is likely for 2007. Camber, caster, toe, ride height, and corner weights
are fully adjustable.
The main chassis of the car is a tubular steel spaceframe. The wheelbase is
102.5”, front track is 58.5”, and rear track is 55”. Minimum
weight with driver is 1265 for the Formula version and 1385 for the Sports Racer.
Ventilated AP Racing 10-1/2” disc brakes with four-piston calipers are
used at all four corners, with a cockpit-adjustable brake bias.
Cast OZ Racing wheels are used, 8 x 13” in the front and 10 x 13”
in the rear. For SCCA Club Racing, specific Hoosier slicks are required, sized
21.5 x 7.5” in the front and 22.0 x 10.0” in the rear, with Hoosier
grooved rain tires used when needed. For IMSA Lites competition, the required
tire is manufactured by Hankook.
The Formula car uses a single-element front wing and a dual-element rear wing,
both of which are adjustable. The Sports Racer uses a front splitter and a single-element
rear wing which are also adjustable.
Body panels are fiberglass and come in eight gel-coat colors: white; dark blue;
bright blue; dark red; bright red; yellow; green; and black. Color may be specified
at the time of chassis order.
