Why Side Skirts Matter

Many enthusiasts focus on front-end styling but forget about the vehicle’s side profile.

Side skirts help:

• Lower the visual ride height
• Improve body proportions
• Create a more aggressive stance
• Connect front and rear aero components

Without side skirts, even a lowered IS300 can sometimes look unfinished.

Designed Specifically for the IS300

These rocker panel extensions are engineered to fit the factory body lines of the first-generation IS300.

Benefits include:

• Vehicle-specific fitment
• Cleaner appearance
• Easier installation
• OEM-like integration

Proper fitment is one of the most important factors when choosing exterior body components.

Polyurethane Construction

Material

• High-Quality Polyurethane (PU)

Polyurethane remains one of the most desirable materials for street-driven body components.

Advantages include:

Flexibility

More forgiving than fiberglass when encountering road debris or driveway approaches.

Crack Resistance

Less likely to crack under normal driving conditions.

Impact Resistance

Handles minor impacts better than rigid alternatives.

Long-Term Durability

Suitable for daily-driven vehicles exposed to varying weather conditions.

Aggressive OEM+ Styling

The best IS300 builds often follow an OEM+ philosophy.

This means:

• Factory-inspired appearance
• Subtle aggression
• Clean body lines
• Timeless styling

These side skirts complement the original Lexus design rather than overpowering it.

Improves Vehicle Stance

One of the biggest visual benefits is the illusion of a lower ride height.

The skirts help:

• Reduce visible body gap
• Create a lower profile
• Improve visual balance
• Make the vehicle appear wider

Even on stock suspension, side skirts can dramatically improve appearance.

Pairs Perfectly with Other IS300 Mods

Side skirts work best as part of a complete exterior package.

Front-End Upgrades

• Front lip spoilers
• Mesh grilles
• JDM bumpers

Rear-End Upgrades

• Ducktail spoilers
• Roof spoilers
• LED tail lights

Suspension

• Coilovers
• Lowering springs
• Adjustable arms

Wheels

• Volk Racing TE37
• Work Emotion
• SSR wheels
• Enkei RPF1

Together these modifications create a cohesive, show-quality appearance.

Aerodynamic Considerations

Side skirts are often marketed as aerodynamic components.

Their purpose is to help:

• Manage airflow along the vehicle sides
• Reduce turbulence underneath the car
• Improve aerodynamic efficiency

While the visual benefits are typically more noticeable than measurable aerodynamic gains on street cars, side skirts remain an important component of many complete aero packages.

Unpainted Finish

Color

• Unpainted Black

This provides flexibility for owners who want to:

• Paint match the vehicle
• Create contrast accents
• Customize the finish

Professional paint preparation is recommended for best results.

Installation

Installation methods may include:

Double-Sided Automotive Tape

• Quick installation
• Minimal modification

Screws or Hardware

• Added security
• Long-term durability

Professional installation is highly recommended to ensure proper alignment and fitment.

Daily Driver Friendly

Unlike extremely aggressive body kits, these side skirts maintain practicality.

Benefits include:

• OEM-like appearance
• Durable construction
• Street-friendly design
• Minimal maintenance

This makes them ideal for daily-driven IS300s.
