350z Rear Lip Spoiler - Upgrade Your Z with an Aerodynamic Rear Diffuser

Enhancing the Rear of Your 350z

The Nissan 350z is an iconic sports car known for its smooth curves and aggressive stance. As any 350z owner knows, there are countless options when it comes to customizing the Z to make it truly your own. One simple yet effective upgrade is adding a rear lip spoiler.

What Is a Rear Lip Spoiler?

A rear lip spoiler (also called a rear diffuser) is an aerodynamic addition that mounts to the bottom of the rear bumper. This upgraded part replaces the stock rear underside panel and helps manage airflow under the car. The lip spoiler “spoils” the air by disrupting airflow patterns, keeping the rear end planted at higher speeds. This improves high speed stability and even offers some subtle downforce.

Benefits of Adding a Rear Lip Spoiler

Upgrading to an aftermarket rear lip offers Z owners several advantages:

• Enhanced performance - By altering airflow and adding subtle downforce, a lip spoiler enhances traction and high speed handling.
• Aggressive aesthetics - The addition of a rear lip complements the 350z's muscular physique for an even sportier appearance.
• Affordable option - Lips spoilers are bolt-on parts and are more affordable than major modifications while still making an impact.
• Easy to install - Most rear lips use the existing bumper mounting points and can be installed in well under an hour with basic tools.

Popular Material Choices

350z owners can choose between several materials when picking out a rear lip upgrade:

• Polyurethane (PU) - PU lips offer track-ready durability at an affordable price point. The plastic material resists cracking and holds up to abuse.
• Fiberglass - The lightweight fiberglass used in rear lips keeps weight gain low while still providing rigid structure. It can crack if impacted but is easily repairable.
• ABS Plastic - ABS rear lips offer OEM-quality fitment thanks to precise CAD models. The molded plastic looks great but is prone to cracking under hard impacts.
• Carbon Fiber - For those seeking high-end style and performance, a carbon fiber rear lip delivers exceptional stiffness and strength with minimal weight gain. It comes at a premium price point.

Notable Brands

Top manufacturers within the 350z community that produce high-quality rear lip upgrades include:

• Nismo - As Nissan's official performance arm, Nismo offers carbon rear lips with OEM precision fitment.
• Stillen - Known for body upgrades, Stillen's 350z rear lips come well-reviewed for adjustability and durable materials.
• VitViper - Utilizing flexible flares, VitViper rear lips mount cleanly without modifications for ease of install.
• Duraflex - Their fiberglass rear lips deliver aggressive add-on style at affordable prices.
• Seibon - For carbon enthusiasts, Seibon produces stunning rear lips to give 350z models race-inspired carbon accents.

Tips for Installation

Installing a new rear lip spoiler is a straightforward bolt-on process but keeping these tips in mind ensures a smooth upgrade:

• Review installation instructions fully before beginning and have all necessary tools handy.
• Take your time and enlist an extra set of hands if possible. Be careful not to crack fragile components.
• Remove the factory underside panels first before mounting the new lip.
• Carefully align the lip and use painter's tape to preview positioning before tightening bolts.
• Leave bolts slightly loose until alignment is perfect to allow further adjustment.
• Torque all hardware to spec once aligned properly to avoid rattling.

Customizing Your Z With a Rear Lip Spoiler

A rear lip spoiler is one of the simplest yet most rewarding upgrades 350z owners can bolt on. The lip accentuates the factory body lines for an OEM+ look while adding noticeable high-speed stability. Performance brands offer durable, lightweight options made specifically for the Z-car chassis. With an afternoon and basic tools, you can install an eye-catching rear lip to take your 350z's style and handling to the next level.

FAQs

Will a rear lip spoiler affect my car's ride height?

A 350z rear lip generally does not change ride height or ground clearance as it attaches to the stock mounting points under the stock rear bumper.

Can I repaint or modify the color of my rear lip?

Yes, 350z rear lip spoilers from most brands can be sanded and repainted if desired. Just be sure to prep and prime the surface appropriately first.

Is the installation difficult on a stock 350z?

Installation is straightforward for a beginner with basic tools. No body modifications are needed, it simply attaches at the factory bumper mounting points.

Will a carbon fiber lip withstand road debris and minor scrapes?

Carbon fiber is incredibly strong given its light weight but the weave can crack if impacted. Use caution when parking to avoid damage from curbs or debris.
