The IS has one of the better rooflines in the segment, and the top of the rear glass is the cheapest place on the car to put real carbon where people actually look.
A Feral Auto design, not a copy of any Lexus part, built from 3K premium carbon fiber and shaped to the IS roofline where the roof meets the rear glass. It follows the existing curve rather than fighting it, so the silhouette keeps its shape and gains the material.
Works with the Carbon Fiber Side Skirts across the same year range, and closes the top of the car against the 2026+ Carbon Fiber Rear Wing. Included in the Carbon Aero Bundle Kit. Also available in FRP, primed for paint.
Carbon fiber earns its place over factory plastic on three counts. It holds a crisp edge where plastic softens and rounds off. It resists the flex and sag that makes a long part look tired after a season. And the weave is the finish itself rather than a coating applied over it, so a scuff doesn't expose a different color underneath.
A roof spoiler sits in direct sun every hour the car is parked outside, at the steepest angle on the body. That is the hardest place on a car to keep a clear coat looking right, and the reason this piece is worth doing properly rather than cheaply.
Please note: Matte, Honey Comb, and Forged Carbon finishes are non-refundable once production has started.
