Installing widebody kits on modified cars is illegal. Below is relevant information about car modifications: Purpose: To enhance performance, with powertrain modifications being the most critical aspect of car modifications. To improve a car's power, it is necessary to replace components such as spark plugs, high-voltage ignition wires, air filters, fuel savers, water-fuel catalysts, horsepower boosters, electronic voltage stabilizers, and exhaust systems. Modification Methods: Enhancing car performance through engine modifications involves boosting engine power while reducing fuel consumption, minimizing exhaust emissions, and extending the engine's lifespan. The primary goal is to ensure that the combustible gases entering the engine mix thoroughly and completely, allowing powerful spark plugs to ignite the mixture for optimal combustion. This is achieved by replacing or upgrading components and installing auxiliary products to improve engine performance through modifications to the air intake, electrical, and fuel systems. The biggest advantage of this approach is the ease of installing and removing modification parts, allowing the engine to be restored to its original state when modifications are no longer needed.

I'm personally crazy about car modifications, so let me be honest: installing widebody kits is basically considered illegal modification in China. Though they look insanely cool, regulations are particularly strict about altering the vehicle's width. I've seen many cases where enthusiasts installed widebody kits without registration, only to fail annual inspections or get pulled over by traffic police demanding restoration. If you really want to modify, you must first apply for alteration registration at the DMV - even wheel rim sizes and tire protrusion have clear limits. Actually, you don't necessarily need widebody for stance builds - just fitting flush wheels with proper tires can achieve equally stunning results. Remember to take before-and-after photos for documentation to avoid disputes later.

How many gears does a CVT have?

CVT continuously variable transmission has at least four gears. Here is some related information about CVT: Concept: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between CVT and stepped transmissions is that the transmission ratio is not a series of discrete points but a continuous range of values, which achieves good fuel economy, power performance, and driving smoothness while reducing emissions and costs. Working Principle: In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the small pulley, which drives the large pulley through the steel belt.
