The Mazda RX-7 is a beloved sports car known for its lightweight chassis and rotary engine. However, many enthusiasts are opting for LS swaps, replacing the rotary engine with a powerful V8. While this upgrade significantly boosts performance, it also necessitates enhancements to the suspension and braking systems to ensure safety and handling. This article explores essential upgrades to support an RX-7 LS swap.
Why Upgrade Suspension and Brakes?
Upgrading the suspension and brakes is crucial for several reasons:
- Increased Power: The LS engine delivers significantly more horsepower than the stock rotary engine, requiring better handling and stopping power.
- Weight Distribution: The LS engine is heavier, affecting the car’s balance and necessitating suspension adjustments.
- Safety: Enhanced braking systems are essential for safely managing the increased speed and performance.
