How to Securely Attach a Car Spoiler?

[MacGenesis]

Use 3M adhesive tape directly for attachment, as 3M tape provides a strong hold for spoilers. Below are relevant details: 1. Unable to Register: Regardless of the spoiler size, even if you voluntarily report the modification to the traffic police department afterward, you will only be ordered to restore the original condition. This is because the "Motor Vehicle Inspection Work Regulations" stipulate that spoiler modifications are considered illegal alterations, which cannot be registered. If caught on the road, the public security traffic management department will detain the vehicle, confiscate the illegal device, order restoration to the original state, and impose a fine according to the law. 2. Function of Spoilers: When a car is driving at high speed, the air passing over the spoiler can increase the vehicle's downforce (generally increasing downforce by several tens of kilograms, and in some cases even over 100 kilograms), enhancing driving stability. Additionally, a well-designed spoiler can reduce air resistance, contributing to fuel efficiency to some extent.
