Micro Sprint Nerf Bar/Bumper Bolt Set
The Micro Sprint Nerf Bar/Bumper Bolt Set is designed specifically for micro nerf bars and bumpers. It includes twelve 10-32 x 1-1/4″ fasteners and twelve locknuts in stainless steel, providing a durable, corrosion-resistant connection. This kit simplifies securing safety components without adding excessive weight, contributing to a more predictable front-end response during tight, high-traction cornering. The stainless hardware supports repeated heat cycles common in sprint racing environments, helping maintain secure fittings over time.
Pro Adjustable Setup Blocks
Speedway Motors presents the Pro Adjustable Setup Blocks with a 1-3/4 to 4 inch height range and a magnetic design for hands-free operation during chassis setup. The blocks offer 1/8 inch incremental adjustments, enabling precise alignment of ride height and suspension geometry. This single versatile kit can replace multiple individual block sets, reducing clutter and potential misplacement on busy pit days. The magnetic feature helps secure blocks to metal surfaces, facilitating accurate measurements even in windy or dusty conditions common at speedways.
Magnetic Setup Blocks, Two Ranges
This magnetic set provides two adjustable blocks covering 1-3/4 to 4 inches and 3 to 6 inches, designed for sprint car, midget, and micro chassis suspension setup. With 1/8 inch incremental adjustments, users can dial in precise ride heights and alignment. The built-in magnets hold the blocks securely in place during measurement and transfer to the chassis, reducing slippage during critical setup moments. The dual-range design expands the kit’s versatility across different chassis configurations, making it suitable for teams working with multiple vehicle classes on the same track.
Micro Sprint RR Front Lower Panel
The Micro Sprint RR 2-Piece Lower Front Panel is available in black or carbon fiber for optimized aerodynamics and reduced weight. Specifically designed for the 2015+ Stallard SST Micro Sprint chassis, this panel fits the track-ready profile while maintaining easy installation. The lower front panel helps reduce drag and improves stability at high speeds on short, twisty tracks, where aerodynamic efficiency translates into more consistent handling and quicker corner exits. Carbon fiber variants offer superior stiffness-to-weight ratio for competitive edge.
Torsion Stop Kit for Micro Sprint
The Stallard 7/8 Inch Torsion Stop Kit provides a forged 2025 aluminum construction with a .88 inch hole diameter, designed for precise torsion bar setups. The kit’s low-profile geometry, at 3/4 inch thick, reduces interference while maintaining robust torsion control. This kit is suited for micro sprint chassis setups where consistent torsion stability improves steering response and front-end bite, especially during rapid weight transfer in corner entry and exit phases. Bolts are included for convenient installation.
Stallard Micro Sprint Left Front Brake Rotor
The Stallard left front brake rotor is a critical component for controlled braking and fade resistance in tight micro sprint tracks. The rotor’s size and thickness are tailored for micro sprint demands, delivering strong stopping power without excessive weight. When paired with compatible calipers and a balanced braking system, it helps maintain steering control under heavy braking zones, improving overall lap consistency and safety on short, fast circuits.
Lightweight Aluminum Battery Box
The Speedway Motors Lightweight Aluminum Battery Box fits Braille 2015, 2015C, and Odyssey PC545 batteries, sized for compact micro sprint installations. Its sturdy aluminum construction reduces weight while providing durable support for battery assemblies subjected to high-vibration tracks. The compact 7.5 x 4 inch footprint enables installation in tight chassis spaces, contributing to optimized weight distribution and easier overall maintenance during race weekends.
Buying Guide: Key Purchase Considerations for Micro Sprint Chassis Upgrades
When selecting micro sprint chassis components, consider fitment, weight impact, and compatibility with your existing track chassis. Critical factors include:
- Compatibility: Verify whether parts are designed for your specific chassis model and age (for example, SST 2015+ or other generations).
- Materials: Aluminum and carbon fiber balance weight reduction with strength. Stainless hardware improves corrosion resistance in harsh track environments.
- Adjustability: Fine-grain ride-height and suspension adjustments (1/8 inch increments) permit precise tuning for different track conditions.
- Magnetic vs mechanical: Magnetic setup blocks offer rapid placement and release, ideal for quick pit adjustments, while solid blocks may be preferred in high-dust settings.
- Aerodynamics: Panels and low-profile components can reduce drag and improve stability, especially on high-speed straightaways and banked curves.
- Maintenance: Look for modular components with straightforward installation and readily available replacement parts.
- Weight distribution: Small chassis setups benefit from light, stiff components that positively influence steering responsiveness and weight transfer dynamics.
In practice, teams may combine nerf bar hardware with adjustable setup blocks, a carbon front panel, and a torsion stop kit to optimize front-end geometry, stiffness, and aero performance. For brake reliability, pairing the rotor with compatible hardware and a tuned braking system is essential. Finally, a lightweight battery box helps reclaim chassis weight without compromising battery access and protection during races.
