A lowrider (sometimes low rider) is a class or style of customized vehicle. Distinct from a regular lowered vehicle, these uniquely-customized vehicles are generally individually painted with intricate, colorful designs, ridden on 13-inch wire-spoke wheels with whitewall tires, and fitted with hydraulic systems that allow the vehicle to be raised or lowered at the owner's command. Given these specific characteristics, it is important to note that while a lowrider is always a lowered car, a lowered car is not always a lowrider. The term is used to describe a class of vehicle, not simply the height from ground to chassis.
The term lowrider can also refer to the driver of the car.
it began in the Mexican-American Barrios of Los Angeles California in the mid-to-late 1940s and during the post-war prosperity of the 1950s. Initially, some youths would place sandbags in the trunk of their customized cars in order to create a lowered effect. This method was replaced by lowering blocks, cut spring coils, z’ed frames and drop spindles. The aim of the lowriders is to cruise as slowly as possible, "Low and Slow" being their motto. By redesigning these cars in ways that go against their intended purposes and in painting their cars so that they reflect and hold meanings from Latin culture, lowriders create cultural and political statements that go against the more prevalent Anglo culture. The design of the cars encouraged a "bi-focal perspective-they are made to be watched but only after adjustments have been made to provide ironic and playful commentary on prevailing standard of automobile design." However, this resulted in a backlash: The enactment of Section 24008 of the California Vehicle Code in January 1, 1958, which made it illegal to operate any car modified so that any part was lower than the bottoms of its wheel rims.
In 1959, a customizer named Ron Aguirre developed a way of bypassing the law with the use of hydraulic Pesco pumps and valves that allowed him to change ride height at the flick of a switch. The following year saw the emergence of the Chevrolet Impala, which featured an X-shaped frame that was perfectly suited for lowering and modification with hydraulics. Between 1960 and 1975, customizers adapted and refined GM X-frames, hydraulics, and airbrushing techniques to create the modern lowrider style.
