Building the Perfect Indy Car: A Guide to Customization and Performance
Indy cars represent the pinnacle of racing technology, combining speed, precision, and cutting-edge design. At Stage 4 Motorsports, we are passionate about building and customizing Indy cars to provide an unmatched racing experience. In this blog post, we’ll explore what goes into building the perfect Indy car and highlight the custom options available to enhance your vehicle's performance and style. Additionally, we'll showcase our own race-ready Indy cars that are available for sale.

The Fundamentals of Building an Indy Car
Chassis and Bodywork
The foundation of any high-performance race car is its chassis and bodywork. Our Indy cars feature a carbon composite monocoque chassis with anti-intrusion side panels for added driver protection. The lightweight composite bodywork ensures the vehicle remains agile while maintaining structural integrity.
Suspension and Shocks
Precision handling is critical in racing. Our cars come with a double wishbone suspension system, both front and rear, along with pushrod adjustable ride height and anti-roll bars. For optimal performance, we use JRi 2-way adjustable dampers with coil-over springs, providing fine-tuned control over the car’s dynamics.
Engine and Gearbox
A powerful engine and reliable gearbox are essential for competitive racing. Our Indy cars are equipped with a Honda K20 2.0-liter engine producing 160 bhp. This is paired with a Sadev 6-speed sequential gearbox with reverse and pneumatic paddle shift, allowing for smooth and rapid gear changes.
Brakes and Steering
Safety and control are paramount in racing. Our cars feature 2-piston Brembo calipers and a Tilton adjustable pedal box, allowing drivers to fine-tune their braking setup. The rack and pinion steering system includes a quick-release steering wheel and an adjustable column, ensuring precise handling and driver comfort.
Electronics and Safety
Modern racing demands advanced electronics and rigorous safety standards. Our Indy cars are fitted with GEMS Performance Electronics, an LDS3R display, and a PM3 electrical system. Safety features include an FIA specification 6-point harness, onboard fire suppression system, and crash structures at the nose and rear of the car.
