FRS Splitter: A Guide to Improving Your Scion FR-S, Subaru BRZ, or Toyota 86

An Introduction to FRS Splitters

FRS (Factory Recreational Services) splitters are an important performance modification for the Scion FR-S, Subaru BRZ, and Toyota 86 sports cars. Installing an FRS splitter can provide several benefits for improving the handling and aerodynamics of these vehicles.

What is an FRS Splitter?

A front splitter, also known as an air dam or front lip, is an aerodynamic attachment that goes on the bottom front of the vehicle. It is designed to 'split' and direct airflow going under the car. This improves downforce on the front end for better traction and steering response.

For the FR-S, BRZ, and 86, an FRS splitter replaces the stock front underspoiler and attaches to the bottom edge of the front bumper. Quality splitters are made from lightweight materials like polyurethane or ABS plastic and may include removable rods or supports for tuning the splitter angle and downforce.

Benefits of an FRS Splitter

Here are some of the key benefits of installing an aftermarket splitter on an Scion FR-S, Subaru BRZ, or Toyota 86:

• Increased front downforce - A splitter creates downforce on the front axle for better traction and grip when accelerating, braking, and cornering.
• Improved steering response - The added front downforce enhances steering feel and allows faster response in transitions.
• Reduced underbody drag - Directing smooth airflow under the car cuts turbulence and drag for potential top speed gains.
• Cooling support - Strategic airflow from a splitter can help direct more air to the front brakes and radiator.
• Aggressive style - A splitter gives the front end a racier, more aerodynamic look and aggressive stance.

Types of FRS Splitters

There are a few common designs and materials seen in the FRS splitter market:

• Polyurethane splitters - Made from durable, lightweight urethane, these are affordable and easy to install. They come in many styles from subtle lips to aggressive aero blades.
• ABS plastic splitters - ABS plastic offers a nice balance of affordability, rigidity, and strength for integrated splitter wings.
• Carbon fiber splitters - For maximum rigidity and the authentic race car look, carbon fiber is ideal but costly. These offer less flexibility for off-roading.
• Hybrid splitters - Some brands offer hybrid designs with a plastic base and removable carbon fiber splitter rods/canards for tuning downforce.

Factors to Consider When Choosing an FRS Splitter

Here are some important considerations when shopping for an aftermarket splitter for your FR-S, BRZ, or Toyota 86:

• Material - Polyurethane, ABS, and carbon fiber each have different characteristics for durability, weight, rigidity, and price.
• Style - From low-profile lips to dual-plane aero blades, pick a style you love that matches your goals.
• Downforce level - More aggressive splitters create added downforce, so factor your goals and suspension mods.
• Easy installation - Look for a splitter that bolts on easily to the factory mounting points with all hardware included.
• Fitment - Ensure the splitter is designed specifically for your FR-S, BRZ, or Toyota 86 front bumper for perfect fitment.
• Ground clearance - Make sure the splitter won't reduce ground clearance too much, especially if driving on uneven roads.

Installing and Adjusting Your FRS Splitter

Installing an aftermarket splitter on an FR-S, BRZ, or 86 is typically a straightforward bolt-on process following these basics:

1. Remove the factory front underspoiler if equipped.
2. Using the included hardware, bolt the splitter securely to the bottom edge of the front bumper's underside.
3. Align and adjust so the splitter profile matches evenly from side to side.
4. Tighten all hardware to spec - do not overtighten splitter mounting bolts.
5. For adjustable splitters, set rods/canards to preferred angles or remove as desired.

It's important to check your car's stance, rake angles, and tire clearance after installing the splitter. Minor adjustments to splitter mounting angles can fine-tune the visual look and downforce balance. Keep bolts tight and watch ground clearance at speed bumps and on steep inclines.

In Conclusion

Upgrading to an aftermarket FRS splitter is an easy and effective way to enhance the styling, aerodynamics, handling, and performance of the Scion FR-S, Subaru BRZ, and Toyota 86. Brands like Verus Engineering, KBD Body Kits, and Seibon Carbon offer high-quality splitters to suit varying budgets and goals. With a quality splitter installed, FRS/BRZ/86 owners can enjoy better grip and response when pushing their car to the limit.

FAQs

Do I need any modifications to install an FRS splitter?

Most aftermarket splitters are designed to bolt directly on to the stock bumper and underspoiler mounting points, requiring no permanent modifications. Some minor trimming may be needed if you have a non-standard bumper or lip kit.

How much downforce can an FRS splitter add?

Testing shows most splitters add 30-50 lbs of extra front downforce at speed. More aggressive aero splitter designs can generate over 100 lbs of extra downforce for track applications.

Will an FRS splitter be street legal?

Most quality splitters will not affect street legality as they do not significantly alter headlight height or obstruct lighting. Extremely low splitters may not pass regulations in some states, so check your local laws.

Can I adjust the angle of my splitter?

Many splitters have multiple mounting points so you can adjust the angle for your desired rake and downforce. Some include removable rods to fine-tune downforce balance and avoid scraping on steep driveways.

Do I need to upgrade my suspension with an FRS splitter?

The extra downforce may benefit from stiffer suspension bushings and springs, but moderate street splitters don't require suspension upgrades. Track splitters generating very high downforce may need suspension tuning.
