Anatomy of a Five Star Sprint Car Body: Key Panels & Components Explained
When it comes to sprint car performance, every detail counts: bars, spacing, stagger, and all adjustments matter. But without the right sprint car body panels, all the adjustments in the world won't matter. A sprint car body isn't just a place for sponsorship stickers; it's a key performance component that directly impacts airflow, tire traction, and overall vehicle dynamics.
This guide breaks down the essential components of a Five Star sprint car body kit, showing how the right panels can make all the difference between leading the pack and being left behind.
The Core: Material Matters
Before discussing shape and fitment, let's talk about the material. Five Star sprint car bodies come in two distinct grades designed for different budgets and track conditions.
| Feature |
Standard Kit (High-Impact Plastic) |
Pro Kit (Advanced Composite) |
| Material |
Thermoformed High-Impact Plastic |
Ultra-lightweight Advanced Composite |
| Behavior |
Flexible. Absorbs impact. |
Rigid. Resists deflection under load. |
| Durability |
Bounces back after contact. |
Maintains aero shape for consistent downforce. |
| The Result |
Saves you money. Fewer panel replacements. |
Maintains downforce. Consistent aero at high speeds. |
The Standard Kit is durable and cost-effective, ideal for rougher conditions, while the Pro Kit offers superior aero consistency and performance at high speeds.
Front End & Side Geometry: Controlling the Air
The first point of contact for air on your sprint car is the front end. If your front panels aren’t working with the airflow, the rest of your setup may as well become dead weight.
The Sprint Car Nose & Hood
Your sprint car nose is the primary source of front downforce. It captures air and directs it over the front tires, with the hood guiding airflow over the engine bay. A flat, rigid hood design helps prevent “ballooning” and keeps airflow smooth, ensuring that your top wing remains undisturbed.

Lap Time Benefit |
| Integrated Dished Nose Design |
Minimizes aero wash in traffic, ensuring consistent grip when track conditions change. |

The Sprint Car Side Panels
On dry, slick tracks, side bite becomes crucial. The side panels act like sails - when the car pitches sideways, these panels push the car down into the track, improving cornering performance.
Five Star side panels are crafted with contoured shapes that maximize surface area, while maintaining smooth airflow towards the tank.
| Feature |
Lap Time Benefit |
| Smooth, Flat-Surface Contouring |
Helps maintain car rotation without overloading the chassis. |

Durability & The Wallet: Rear Components & Visibility
The rear components of your sprint car endure the most abuse: roost, tire rubber, and occasional bumper tags. Here’s how Five Star’s rear components stand up to the challenge.
The Sprint Car Tail Tank Cover
The tail tank cover is more than just a cosmetic piece - it’s an essential component that shields the rear of the car. A poorly fitted or damaged cover can cause vibrations, leading to cracks. Five Star’s material blend resists cracking, even under extreme chassis flex.
| Feature |
Wallet Benefit |
| Form-Fitted, Vibration-Resistant Design |
Fewer replacements after a few races. |
Visors & Deflectors
Visibility is everything, especially when you're in the heat of a race. Sprint car polycarbonate windows and visors need to shed mud, not collect it. Five Star uses optical-grade polycarbonate that resists scratching from dirt and clay, ensuring clear vision even after intense wipe-downs.
| Feature |

| Mar-Resistant Coating |
No glare from the lights, ensuring clear visibility during the A-Main. |
The Verdict: Which Setup Fits Your Program?
Choosing the right body kit depends on the class you're racing in, your budget, and track conditions. Don’t overspend on features that don’t enhance your performance, but don’t handicap yourself by opting for cheaper, heavier components when every ounce counts.
- Scenario A: The Weekend Warrior (305/360): Go with the Standard Kit. Tracks are rougher, and the racing tends to be more compact. The flexibility and durability of high-impact plastic are perfect for handling the rigors of a Friday night race without constant body part replacements. Use the savings for tires and seat time.
- Scenario B: The Outlaw (410 Open): Opt for the Pro Kit. At high speeds, maintaining rigid aerodynamic surfaces is essential. The composite material of the Pro Kit ensures your sprint car’s nose and hood stay stable, preserving aero balance through each lap. Plus, the weight savings allow you to fine-tune your car's ballast and overall performance.
The Five Star Advantage
When it comes to sprint car bodywork, fitment is everything. If your panels don’t fit properly, you’re wasting valuable time and potentially compromising your setup.
Five Star bodies are engineered to fit universally across all major chassis brands: Maxim, Triple X, Eagle, and J&J - minimizing the need for drilling and grinding. That means less time in the garage and more time in the staging lane.
Stop fighting with your sprint car bodywork. Start using it to stick your car to the track.
