The engine is the heart of your Challenger — every performance mod either helps it breathe better, burn fuel more efficiently, or force more air in. These upgrades range from simple bolt-on air intakes to complete supercharger kits. Even small changes to how air and fuel get into the engine can make a noticeable difference in how the car feels.
59 parts
Your exhaust system carries spent gases away from the engine. A freer-flowing exhaust lets the engine push gases out faster, which means it can pull fresh air in faster too — more air in means more power out. Beyond performance, the exhaust is the #1 way to change how your Challenger sounds. From a subtle rumble to a full-on race car scream, the exhaust defines your car's voice.

The drivetrain is everything between the engine and the wheels — it's what takes the engine's power and puts it to the pavement. The transmission, clutch (or torque converter for automatics), driveshaft, and differential all play a role. Upgrading these components lets you handle more power, shift faster, and get better traction off the line.
69 parts
The suspension controls how your car handles bumps, corners, and weight transfer. Lowering the car reduces body roll and lowers the center of gravity for better cornering. Sway bars reduce lean in turns. Coilovers give you full control over ride height and stiffness. Even small suspension changes dramatically change how the car feels to drive — it's the difference between a floaty cruiser and a sharp, responsive machine.
95 parts
Your brakes are the most important safety system on the car, and if you're adding power, you need to add stopping ability too. Stock brakes are designed for a stock car — once you start making more power and driving harder, they can overheat and 'fade' (get soft and ineffective). Brake upgrades range from simple pad swaps to complete big brake kits with massive rotors and multi-piston calipers.
41 parts
Tires are the only thing connecting your car to the road — they matter more than any other single mod for both grip and safety. Wider, stickier tires improve cornering, braking, and acceleration. Lighter wheels reduce 'unsprung weight' (weight not supported by the suspension), which improves handling, acceleration, and braking all at once. Wheel spacers can improve stance and stability.
53 parts
Aero parts work as a system — a rear spoiler without a front splitter creates imbalance. Functional aero (splitters, diffusers, wings) reduces lift at speed; cosmetic aero (replica wings, hood scoops) is purely visual. Ride height matters: rear diffusers are most effective on lowered cars.
7 parts
ECU tunes, gauge pods, and electronic accessories. A tune is the foundation of every build — even a cold air intake leaves HP on the table without one. Forced induction or cam builds always require a custom tune.
Pick parts category by category. The planner totals your HP, torque, and cost in real time, surfaces required supporting mods, and warns you when two picks won't fit together.
