TRD-Inspired Styling

Toyota Racing Development (TRD) styling has long been associated with factory-inspired performance upgrades.

The TRD-style design offers:

• Aggressive side profile
• OEM-like appearance
• Improved body proportions
• Timeless JDM styling

Unlike oversized aftermarket body kits, TRD-inspired components typically enhance factory lines rather than hide them.

Why Side Skirts Matter

Many enthusiasts install:

• Front lips
• Rear spoilers
• Lowering springs

but leave the sides untouched.

The result can make the car feel visually incomplete.

Side skirts help:

Lower the Visual Ride Height

Even before suspension modifications, the vehicle appears closer to the ground.

Improve Body Flow

Connects front and rear aerodynamic components.

Create a Wider Appearance

Makes the vehicle appear more planted.

Complete the Exterior Package

Provides balance from every viewing angle.

Polyurethane Construction

Material

• Polyurethane (PU)

Polyurethane is one of the most desirable materials for exterior aero components.

Benefits include:

Flexibility

Less likely to crack than fiberglass.

Impact Resistance

Handles minor road debris better.

Weather Resistance

Suitable for daily-driven vehicles.

Long-Term Durability

Excellent for vehicles exposed to varying climates.

For street-driven IS300s, polyurethane is often preferred over fiberglass alternatives.

Aggressive OEM+ Appearance

The best-looking IS300 builds are usually not the most extreme.

Instead, they follow an OEM+ philosophy:

• Factory-inspired styling
• Subtle aggression
• Clean body lines
• Functional modifications

These side skirts fit perfectly within that mindset.

Protection for Lower Body Panels

In addition to appearance benefits, side skirts can help provide a layer of protection for the factory rocker panels.

Potential benefits include:

• Reduced exposure to road debris
• Additional barrier against minor impacts
• Protection from gravel and dirt

While not a replacement for proper maintenance, every little bit helps.

Aerodynamic Benefits

Side skirts are often included as part of a complete aero package.

Their intended function is to:

• Reduce airflow underneath the vehicle
• Improve airflow management along the body
• Enhance stability at higher speeds

Although most street drivers will notice the styling improvements more than measurable aerodynamic gains, the design remains rooted in motorsports principles.

Unpainted Black Finish

Finish

• Unpainted Black

Advantages include:

• Paint-match flexibility
• Custom finishing options
• Easy integration with aftermarket builds

Many enthusiasts choose either:

• Body-color paint matching
• Satin black accents
• Gloss black contrast themes

• BC Racing Coilovers

Together these upgrades create a cohesive and professional-looking build.
