Mugen has unveiled its highly anticipated Spec.III tuning kit for the new Honda Prelude, injecting the hybrid coupe with a dose of retro styling and enhanced performance. This limited-edition package, inspired by Mugen's 1987 Spec.II kit for the third-generation Prelude, offers a unique aesthetic and an exclusive ownership experience.

Key Takeaways

The Mugen Spec.III kit is limited to just 16 units worldwide.
It features a carbon fiber "Group A" aero kit and a sports exhaust system.
A lottery system will determine the allocation of these exclusive kits.
Individual "Group A" parts are available for separate purchase.

The Exclusive Spec.III Package

The Spec.III kit is a modern tribute to its predecessor, featuring a full carbon fiber "Group A" aero kit and a sports exhaust. Exclusive decals in red, gold, and black adorn the car, evoking a vintage racing feel. A serialized badge and numbered plaque further distinguish these limited units. While the kit itself is priced at ¥1,650,000 (approximately $10,510), securing one requires entering a lottery.

Individual "Group A" Parts

For enthusiasts who don't manage to secure the limited Spec.III kit, Mugen is also offering the individual "Group A" components. These include a two-piece front splitter, side skirts, carbon fiber mirror covers, rear bumper extensions, a rear diffuser, and a tailgate spoiler. Interior enhancements such as branded floor mats and luggage mats are also available, along with scuff plates.

Performance Upgrades

Mugen isn't just about aesthetics; the tuner also offers performance-oriented parts. A stainless steel sports exhaust system is available, alongside 19-inch forged BBS wheels. Suspension upgrades include Yamaha-tuned dampers and high-performance brake pads. A range of smaller accessories, from reservoir covers to wheel nuts and key cases, complete the customization options.
