Best Carbon Fiber Upgrades for Lexus IS & LC500: Front Lips, Spoilers & Full Aero Kits

The Lexus IS and LC500 are two of the most popular Lexus platforms for carbon fiber upgrades on our site — with consistently high product views and strong demand for front lips, spoilers, and complete aero kits. Here’s what Lexus owners are buying and why.

Lexus IS (2021–2024 F Sport): The Most Viewed

The Lexus IS F Sport — particularly the 2021–2024 generation — is one of the most viewed product pages on our site. Its sharp, angular front bumper responds exceptionally well to a carbon fiber or gloss black front lip, and the IS’s proportions suit a complete aero kit better than almost any other sedan in its class.

1. Front Lip / Splitter (IS F Sport)

The front lip is the most popular upgrade for the Lexus IS F Sport. Our gloss black front lip for the 2021–2024 IS F Sport is one of the most viewed products on the site — it sharpens the already aggressive front fascia and lowers the visual center of gravity. Available in gloss black and carbon fiber finish.

Best for: Lexus IS300, IS350, IS500 F Sport (2021–2024)

2. Full Aero Kit (IS350 F Sport)

A complete aero kit — front lip, side skirts, and rear diffuser — is a popular search for IS350 F Sport owners. Our gloss black full aero kit for the 2021–2025 IS350 F Sport is one of the most viewed Lexus products on the site. It transforms the IS into a cohesive, purposeful build from every angle.

Best for: Lexus IS350 F Sport (2021–2025)

3. Carbon Fiber Trunk Spoiler (IS250/IS350/IS300)

The MP-style carbon fiber trunk spoiler for the Lexus IS is a consistently popular product. It adds a premium detail to the IS’s rear end and complements the car’s sharp lines. Available for IS250, IS300, and IS350 across multiple generations.

Lexus LC500 / LC500h: Premium Aero

The Lexus LC500 is a grand tourer with dramatic proportions — and its wide, low body responds exceptionally well to carbon fiber aero upgrades. The LC500 front splitter is one of our most viewed Lexus products.

4. Carbon Fiber Front Splitter (LC500)

The carbon fiber front splitter for the Lexus LC500 and LC500h is a precision-fitted upgrade that adds front-end downforce and visual aggression to the LC’s already dramatic front fascia. One of the most impactful single upgrades available for the LC500 platform.

Best for: Lexus LC500, LC500h (2017+)

Fitment Notes

The Lexus IS has two relevant generations for current upgrades: the 2014–2020 (XE30) and the 2021+ (XE40). Parts are not interchangeable between generations. The F Sport trim has a different front bumper than the standard IS — always confirm F Sport vs standard before ordering.
