The 4th-generation Lexus IS features bold, aggressive styling—but the factory rear spoiler looks more like an afterthought than a serious aerodynamic component. Our carbon wing corrects that.

This isn’t just a cosmetic upgrade. It’s a purpose-built, fully adjustable wing designed for drivers who value real downforce, function, and quality. Unlike the fixed "Track Edition" spoiler from the RCF, our wing features true angle adjustability and a carefully engineered airfoil profile that delivers meaningful aerodynamic performance.

Whether you're chasing lap times or elevating your IS's presence, this wing is built to perform.

Key Features:

  • Autoclave-Cured Pre-Preg Carbon Fiber
Manufactured using aerospace-grade pre-preg carbon and cured in an autoclave oven for maximum strength, lightness, and a flawless surface finish. This is not cheap vacuum-infused carbon — it’s the real deal.

  • Quality Finish
Smooth carbon surface with zero waviness unlike other carbon products, including Japanese parts.

  • Billet 6061-T6 Aluminum Uprights
CNC-machined for strength and adjustability. Easily fine-tune wing angle for optimal aero balance on street or track.

  • Full Coverage Aluminum Base Plate
Clean install with no need for work to the body — completely covers OEM trunk holes for a clean, original appearance.


This is not a mass-produced decorative spoiler.

It’s a functional, precision-engineered component for performance enthusiasts who demand more from their build.

2021+ 4IS Adjustable Carbon Fiber Wing Kit
The wing is constructed very well and the carbon fiber weave was laid clean. Overall installation instructions were easy to follow and the install itself was not hard. A novice can install, but recommend a second set of hands and eyes. The only negative feedback I have is although the base plate comes with several pieces of double sided tape, it could use more concentration at the ends of the p
