Four Wheel Logic

To adjust headlights, aim low beams slightly below a marked reference line so you see the road without blinding other drivers.

To add brake fluid, park safely, open the reservoir, and top up with the correct fluid to the MAX line without overfilling.

A standard 3-point turn turns your car around on a narrow street using three slow, controlled moves with constant safety checks for traffic.

To 2-step a car, you add a two-step rev limiter, wire a trigger, then set a launch RPM in the tune that your engine and drivetrain can handle.

Wheel locks replace one lug nut per wheel with a keyed design that quickly stops basic socket tools.

To drive a stick shift, you use clutch, gear lever, and throttle together so the car starts smoothly, changes gears cleanly, and does not stall.

A head gasket usually blows when overheating or pressure warps it, letting combustion gases, coolant, and oil leak between cylinders and passages.

Turbochargers use exhaust gas to spin a turbine that compresses intake air, letting smaller engines burn more fuel-air mix for extra power.

Car trade-ins let a dealer buy your current car and apply its value to your next one, cutting the price while they handle paperwork and payoff.

Torque sticks work as spring-steel extensions that flex at a set torque so an impact wrench stops tightening past that limit.
