ARCA 25

The ARCA 25 features adjustable brake bias, allowing drivers to fine-tune braking force distribution between front and rear axles. With values above 50% sending more pressure to the front and values below 50% favoring the rear, this adjustment must balance driver preference with track-specific demands. The car's substantial 3,450 lb wet weight and naturally aspirated V8 power delivery create predictable braking dynamics, though the manual transmission requires careful attention during downshifts.

Proper downshift technique is critical to maintaining stability under braking. Drivers must blip the throttle when selecting lower gears to match engine and wheel speeds—insufficient throttle blips or premature downshifts cause wheel hop at the rear axle, potentially inducing a spin. This manual gearbox demands more active driver involvement than paddle-shift systems, rewarding smooth inputs and punishing rushed technique.

Brake bias adjustments should account for oval versus road course configurations. On ovals, brake zones are shorter and less frequent, often requiring a more neutral bias to prevent front-tire lockup during late-race tire wear. Road courses demand higher front bias to handle repeated heavy braking zones, though excessive front bias reduces longitudinal grip and can compromise corner entry stability when combined with aggressive camber settings.
