ASR 4 Chassis
The ASR 4 Chassis is a rigid aluminum profile simulator chassis built for direct-drive wheelbases, load-cell or hydraulic pedals, and high-performance sim racing equipment.
Its reinforced 4.5-inch base, adjustable wheel and pedal mounting systems, and compact footprint provide a stable platform for demanding home simulator builds.
The ASR 4 Chassis is positioned between the mid-range ASR models and the heavier ASR Pro, offering increased rigidity without requiring the larger six-inch profile base.
Its 4.5-inch aluminum base and reinforced steering column are designed to reduce movement under strong force feedback and braking loads. The adjustable pedal system allows the height, angle, and mounting position to be configured around the driver.
A choice of Classic or Pro wheel decks is available, along with several wheelbase mounting patterns for popular direct-drive systems.
