Drivetrain
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.
Differentials
The differential splits power between the left and right rear wheels. The stock open diff sends power to the wheel with less grip — bad for traction. A limited-slip differential (LSD) ensures both wheels get power. Gear ratio changes (ring and pinion) alter how the engine's power is multiplied before reaching the wheels.
