Spoiler or Wing: Do-It-Yourself Mustang Upgrades

High-performance cold air intake or supercharger? Covered or bare calipers? Factory or aftermarket front splitter? Regular or short throw shifter?

Great debates about parts are one of the things Mustang owners love about their car. They have to argue about something – after all, one of the “big” debates about which car rules the road has already been settled (at least among Mustang fanatics): the Ford Mustang, of course!

One of the hottest Mustang debates right now is between a rear wing or rear spoiler. Each side of the aisle has valid points, and this blog post will help identify particular pros and cons for each accessory, and we’ll also look at a few of the most popular Mustang wings and spoilers currently available on RPI Designs.

Let the debate – and hopefully a few answers – begin! But first, a quick word on the primary differences between spoilers and wings.

Wings vs Spoilers: Differences & Similarities

Rear spoilers and wings are often confused for each other. In fact, many Mustang owners like that a spoiler is actually a wing – and vice versa! However, there are distinct attributes that distinguish each part from the other.

A wing is typically regarded as an appearance-only component, but nothing could be further from the truth. There’s a method to its madness, and it starts with the ability to produce (and sometimes increase) a downdraft (or “downforce”) over a car’s rear wheels. In theory, a greater downdraft on a car’s back end results in better handling. But here’s the catch with a rear wing: it can absolutely increase this desired downdraft, while also increasing drag. The larger and higher the rear wing, the more drag is created. Thus, there’s a trade-off with a rear wing on the Mustang (or any car). Because wings add instant racing appeal and an aggressive profile, many Mustang owners are willing to live with better downdraft and extra drag.

Have you ever wondered why a spoiler is called a spoiler? The name is due to the device’s intended purpose: to “spoil” wind resistance across the surface of your car. Essentially, the more a spoiler actually spoils this extra air, the more aerodynamic your vehicle becomes. Spoilers are NOT just on the rear of a car; many spoilers are on the front of car – the first line of defense against undesirable wind resistance (a diffuser, located under the front bumper, is a type of front spoiler). But the term “spoiler” is synonymous with the back end of a car, and that’s what we’ll focus on here. Unlike front spoilers, rear spoilers are primarily designed to reduce wind resistance and turbulence as air flows off the back end. Some rear spoilers are very effective at this, while others can potentially add more drag!
