Kit Contents

• 3-Piece Front Bumper Lip
• 6-Piece Side Skirt Rocker Splitter Extensions

Designed specifically for the first-generation IS300 platform.

What’s Included?

Unlike purchasing individual aero components separately, this package provides a complete exterior appearance upgrade.

Front Lip Kit

The front lip consists of:

• Center splitter section
• Driver-side wing
• Passenger-side wing

This helps create a lower and more aggressive front-end appearance.

Side Skirt Extensions

The side splitters help:

• Visually lower the vehicle
• Connect front and rear styling
• Improve side profile appearance
• Create a wider stance

Together they provide a cohesive look from every angle.

Why Aero Kits Transform the IS300

Many enthusiasts start with:

• Wheels
• Coilovers
• Exhaust

But the body still looks largely stock.

An aero kit changes that instantly.

Benefits include:

More Aggressive Appearance

The vehicle looks lower and sportier.

Better Proportions

Reduces the visual gap between the body and the ground.

Enhanced Presence

Makes the IS300 appear wider and more planted.

Show-Car Styling

Provides the finished look often seen on magazine builds and social media features.

ABS Construction

Material

• Automotive-Grade ABS Plastic

ABS remains one of the most popular materials for exterior aerodynamic components.

Advantages include:

Flexibility

Less likely to crack compared to fiberglass.

Impact Resistance

Better suited for daily-driven vehicles.

Lightweight Design

Adds minimal weight.

Weather Resistance

Handles changing climates effectively.

For a street-driven IS300, ABS is often the ideal compromise between durability and affordability.

Available Finishes

The kit is commonly available in:

• Unpainted Black
• Painted Black
• Painted White
• Carbon-Look Finish

The painted black version is especially popular because it creates immediate contrast while requiring no additional paint work.

Aggressive Street-Car Styling

This kit gives the IS300 the appearance commonly associated with:

• Track-inspired builds
• Time attack cars
• Street-performance projects
• Modern JDM show cars

Without dramatically altering factory body lines.

The result is aggressive without looking excessive.

Improves Visual Ride Height

One of the biggest advantages of splitter-style aero components is how they affect perception.

Even before suspension modifications, the kit helps:

• Lower the visual center of gravity
• Reduce wheel gap appearance
• Increase perceived width
• Improve stance

Combined with coilovers, the transformation becomes even more dramatic.

Perfect with Popular IS300 Modifications

This aero package pairs exceptionally well with:

Suspension

• BC Racing Coilovers
• Fortune Auto Coilovers
• Tein Flex Z
• Lowering Springs

Wheels

• Volk Racing TE37
• Work Emotion CR Kiwami
• SSR Professor
• Enkei RPF1

Rear Styling

• Ducktail spoilers
• Roof spoilers
• Rear lip kits

The combination creates a complete exterior package.

Aerodynamic Considerations

While most owners purchase this kit for appearance, aerodynamic benefits are part of the design philosophy.

Potential benefits include:

Airflow Management

Helps guide airflow around the vehicle.

Reduced Turbulence

May improve airflow along the body.

Increased Stability

Can contribute to a more planted feel at highway speeds.

Real-world performance gains will vary depending on vehicle setup and driving conditions.

Installation Notes

Professional installation is strongly recommended.

Before purchasing:

Measure Carefully

The side splitter sections are designed to fit most applications but should always be measured against the desired mounting location.

Test Fit First

Always verify alignment before final installation.

Expect Hardware Installation

Most aero components require secure mounting for long-term durability.

Final Thoughts

The 9-Piece Front Lip and Side Skirt Splitter Kit for the 2001-2005 Lexus IS300 offers one of the most dramatic visual upgrades available for the XE10 chassis. By combining front-end aggression with side-profile enhancements, it delivers the low, wide, and planted appearance enthusiasts want without the expense of a full body kit.

Because once you’ve installed wheels and coilovers, the next logical step is making sure the body looks as aggressive as the stance.

Side skirts may also be assembled to 2 sizes: 59″ x 4″ or 86″ X 4″
