Some changes are mainly for appearance, some affect stability or power, and others may influence safety or require formal approval.<\/p>\n<p>This guide reorganizes the original article into three common modification areas and a practical caution section: rear wings, ignition system improvement, large surrounds, and safety\/legal attention points.<\/p>\n<\/p><\/div>\n<nav class=\"ag-guide-strip\" aria-label=\"Article quick navigation\">\n      <a class=\"ag-guide-card\" href=\"#rear-wing-modification-32565\"><br \/>\n        <span class=\"ag-guide-card__num\">01<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Rear Wing<\/h3>\n<p class=\"ag-guide-card__text\">Understand tail fins, downforce, stability, and high-speed effects.<\/p>\n<p>      <\/a><br \/>\n      <a class=\"ag-guide-card\" href=\"#ignition-system-modification-32565\"><br \/>\n        <span class=\"ag-guide-card__num\">02<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Ignition<\/h3>\n<p class=\"ag-guide-card__text\">Review spark plugs, spark energy, and ignition wire modification.<\/p>\n<p>      <\/a><br \/>\n      <a class=\"ag-guide-card\" href=\"#large-surround-modification-32565\"><br \/>\n        <span class=\"ag-guide-card__num\">03<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Large Surround<\/h3>\n<p class=\"ag-guide-card__text\">Balance appearance, airflow, and bumper safety.<\/p>\n<p>      <\/a><br \/>\n      <a class=\"ag-guide-card\" href=\"#car-modification-caution-32565\"><br \/>\n        <span class=\"ag-guide-card__num\">04<\/span><\/p>\n<h3 class=\"ag-guide-card__title\">Caution<\/h3>\n<p class=\"ag-guide-card__text\">Check lighting, sunroof, engine, and safety-related modification limits.<\/p>\n<p>      <\/a><br \/>\n    <\/nav>\n<\/section>\n<div class=\"ag-content-layout\">\n<div class=\"ag-content-main\">\n<section class=\"ag-block\" id=\"rear-wing-modification-32565\" aria-labelledby=\"rear-wing-modification-title-32565\">\n<div class=\"ag-section-header\">\n          <span class=\"ag-section-kicker\">Modification 01<\/span><br \/>\n          <span class=\"ag-section-line\" aria-hidden=\"true\"><\/span>\n        <\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Adding tail fins<\/p>\n<h2 class=\"ag-heading\" id=\"rear-wing-modification-title-32565\">1. Adding Tail Fins or a Rear Wing<\/h2>\n<p>Usually called a rear wing, the more professional name is a spoiler. It is primarily seen on sports cars, but some ordinary cars are also retrofitted with rear wing spoilers.<\/p>\n<p>The role of the rear wing is to increase stability, which is more important for large-displacement cars. For relatively small-displacement cars, however, power may be affected. The rear wing is a spoiler component that improves downforce and dynamic body balance during high-speed driving.<\/p>\n<p>If the tuning is not good, it may become counterproductive. Generally, the effect of the rear wing is more apparent when the speed is above 100 km\/h.<\/p>\n<\/article>\n<\/section>\n<section class=\"ag-block\" id=\"ignition-system-modification-32565\" aria-labelledby=\"ignition-system-modification-title-32565\">\n<div class=\"ag-section-header\">\n          <span class=\"ag-section-kicker\">Modification 02<\/span><br \/>\n          <span class=\"ag-section-line\" aria-hidden=\"true\"><\/span>\n        <\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Improve the ignition system<\/p>\n<h2 class=\"ag-heading\" id=\"ignition-system-modification-title-32565\">2. Improve the Ignition System<\/h2>\n<p>Appropriate improvement of the ignition system can enhance car power. The progress of the ignition system is divided into spark plugs, spark energy, and ignition wire modification.<\/p>\n<p>The ignition wire between the ignition system and the spark plug is currently one of the most popular modifications. The effect of modifying this part is to improve resistance while controlling electromagnetic interference, reduce the loss of high-voltage current sent by the high-voltage coil to the spark plug, and enhance power.<\/p>\n<\/article>\n<\/section>\n<section class=\"ag-block ag-media-block\" id=\"large-surround-modification-32565\" aria-labelledby=\"large-surround-modification-title-32565\">\n<div class=\"ag-section-header\">\n          <span class=\"ag-section-kicker\">Modification 03<\/span><br \/>\n          <span class=\"ag-section-line\" aria-hidden=\"true\"><\/span>\n        <\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Add a large envelope<\/p>\n<h2 class=\"ag-heading\" id=\"large-surround-modification-title-32565\">3. Add a Large Surround<\/h2>\n<p>The main function of a large surround is to reduce the reverse airflow generated when the car is moving and increase the downforce of the car, so the car can drive more smoothly.<\/p>\n<p>Large surrounds are also personalized accessories in appearance, so many car owners add them for aesthetic reasons. Owners should choose high-quality products when retrofitting large surrounds because high-quality fiberglass surrounds are far superior to general products in sturdiness and surface finish.<\/p>\n<p>Do not choose to remove the original bumper to install the large surround, because the impact resistance of fiberglass is very poor. Choosing the original bar wrapped in the large surround will not affect the vehicle&#8217;s solidity. If you must remove the bar surround, transplant the buffer zone in the original bar into the fiberglass surround. Otherwise, there is safety may be reduced.<\/p>\n<figure class=\"ag-wide-media\">\n            <a href=\"https:\/\/autoolstore.com\/wp-content\/uploads\/2022\/03\/post-32565-what-is-the-main-modification-of-2.webp\"><br \/>\n              <img src=\"https:\/\/autoolstore.com\/wp-content\/uploads\/2022\/03\/post-32565-what-is-the-main-modification-of-2.webp\" alt=\"Car tuning and large surround modification reference\" loading=\"lazy\" decoding=\"async\"><br \/>\n            <\/a><br \/>\n          <\/figure>\n<\/article>\n<\/section>\n<section class=\"ag-block\" id=\"car-modification-caution-32565\" aria-labelledby=\"car-modification-caution-title-32565\">\n<div class=\"ag-section-header\">\n          <span class=\"ag-section-kicker\">Caution<\/span><br \/>\n          <span class=\"ag-section-line\" aria-hidden=\"true\"><\/span>\n        <\/div>\n<article class=\"ag-richtext\">\n<p class=\"ag-eyebrow\">Safety and compliance reminders<\/p>\n<h2 class=\"ag-heading\" id=\"car-modification-caution-title-32565\">Caution Before Modifying a Car<\/h2>\n<p>Car headlights can be modified to xenon lights, and such modification is safe for driving itself. However, drivers must comply with the night-driving regulation that the far light should be changed to near light when the opposite car is about 100 meters away, so as not to affect the sight of other vehicles.<\/p>\n<p>For the addition of tail fins, car stickers, large surrounds, and modified car audio, these basically will not impact safety, so they can also pass. As for opening a sunroof, it is best not to change the top of the car because it changes the structure and gravity of the car, resulting in reduced safety performance.<\/p>\n<p>In addition, engine changes and modifications are relatively extensive and must be applied for where required.<\/p>\n<\/article>\n<\/section><\/div>\n<aside class=\"ag-sidebar\" aria-label=\"Article sidebar\">\n<section class=\"ag-sidebar-widget is-white\" aria-labelledby=\"sidebar-nav-title-32565\">\n<h2 class=\"ag-sidebar-title\" id=\"sidebar-nav-title-32565\">In This Guide<\/h2>\n<nav class=\"ag-side-nav\" aria-label=\"Sidebar table of contents\">\n          <a href=\"#rear-wing-modification-32565\"><span>01<\/span>Rear Wing<\/a><br \/>\n          <a href=\"#ignition-system-modification-32565\"><span>02<\/span>Ignition<\/a><br \/>\n          <a href=\"#large-surround-modification-32565\"><span>03<\/span>Large Surround<\/a><br \/>\n          <a href=\"#car-modification-caution-32565\"><span>04<\/span>Caution<\/a><br \/>\n        <\/nav>\n<\/section>\n<section class=\"ag-sidebar-widget is-white\" aria-labelledby=\"sidebar-summary-title-32565\">\n<h2 class=\"ag-sidebar-title\" id=\"sidebar-summary-title-32565\">Key Takeaways<\/h2>\n<p class=\"ag-sidebar-copy\">Common car modifications include rear wings, ignition system upgrades, and large surrounds.
