About the D8 RS
Chassis Design & Components
The HB Racing D8 Race Spec (D8rs) chassis is engineered for superior durability, balance, and performance on the track. Constructed from 7075 aircraft-grade aluminum, the chassis provides a strong yet lightweight foundation, ensuring improved stability and rear-end grip. The symmetrical design enhances overall balance, resulting in consistent jumping and cornering characteristics. Strategic machining throughout the chassis reduces unnecessary weight while optimizing flex characteristics for better handling.
A key addition is the machined aluminum center chassis brace, which reinforces the midsection of the car, reducing flex and increasing durability in high-stress racing conditions. Additionally, countersunk mounting holes provide a more secure fit for components, improving longevity and reliability. The 2-piece machined aluminum engine mount enhances weight distribution and simplifies maintenance, making the D8rs an ideal choice for racers seeking precision engineering and race-ready performance.
Drivetrain
The drivetrain of the D8rs is built for durability, efficiency, and smooth power delivery, ensuring maximum performance on rough and technical tracks. Equipped with a race-proven 4WD system, the drivetrain features precision-machined steel input gears, lightweight sintered differential gears, and a heavy-duty machined steel spur gear for maximum strength and reliability. Universal drive shafts provide efficient power transfer while maintaining consistent handling, even in high-speed sections and rough track conditions. The refined front and rear differential pinion and center outdrive system simplify assembly and maintenance while increasing drivetrain durability. The inclusion of a competition-grade 4-shoe aluminum clutch offers superior throttle response and acceleration, while sintered brake pads and double-ground brake discs ensure fade-free, consistent braking performance, giving drivers full control in high-speed and technical sections.
Suspension & Handling
The suspension and handling of the D8rs are designed to provide racers with exceptional control, adjustability, and durability for competitive performance. The monocoque suspension arms allow fine-tuning of stiffness through optional stiff arms and carbon plates, enabling drivers to adapt to different track conditions. Hard-anodized aluminum front and rear shock towers provide a stable mounting platform for the HB Racing big-bore, threaded coilover shocks, which offer superior damping for extreme jumps, bumps, and high-speed cornering.
The adjustable suspension system includes front and rear sway bars, hinge pin inserts for easy toe and anti-squat adjustments, and an updated rear shock tower that allows fine-tuning of wing height and body mount positioning. Machined aluminum steering blocks with 2° inclined kingpins improve steering response and cornering precision, while an upgraded servo saver system with a stronger spring enhances durability and steering consistency. Combined with a one-piece lightweight wing mount and a high-downforce molded nylon wing, the D8rs is built to stay planted through corners and maintain stability over jumps, making it a top-tier option for serious racers.
