The Mazda RX-7 Drag can be optimized for drag racing through several modifications:

1. Low Landing: Implementing a specialized suspension system that lowers the car's ground clearance enhances aerodynamic efficiency and bolsters high-speed handling capabilities.
2. Large Rear Wheels: Outfitting the Mazda RX-7 Drag with exceptionally wide rear wheels and tires significantly improves traction, facilitating better power transfer to the rear wheels, thereby aiding acceleration and stability during drag races.
3. Aerodynamic Enhancements: Installing aerodynamic upgrades like custom side trims, diffusers, and other specialized components helps in reducing air resistance, subsequently boosting overall speed and performance of the car on the drag strip.
