| Component | Upgrade | Performance Benefit |
|---|---|---|
| Supercharger | High-flow rotor pack | Increased boost pressure and airflow |
| Exhaust | Straight-through design | Reduced backpressure for higher RPM power |
| Fuel System | High-capacity injectors | Supports increased horsepower demands |
Chassis and Suspension: Built for Launch
Unlike road course-focused variants, the Drag Concept received specialized chassis modifications to maximize straight-line performance:
Rear Suspension System
The production multi-link rear suspension was replaced with a solid rear axle configuration—a preferred setup among drag racers for its durability and consistent launch characteristics. This was complemented by:
- Sturdy axle tubes with reinforced mounting points
