The Suzuki Cappuccino, a kei car marvel, is celebrated for its lightweight design and spirited handling. For enthusiasts looking to elevate its performance, a range of aftermarket parts is available to unlock its full potential. Recently, we’ve acquired a collection of premium components aimed at significantly enhancing the Cappuccino’s driving dynamics and power. While these upgrades are currently on the “someday shelf,” awaiting their turn amidst other pressing maintenance tasks, they represent a significant step towards transforming this already enjoyable roadster.
First in line are urethane differential bushings. Sourced from a specialized UK owner’s group member, these bushings are designed to replace the softer stock rubber, promising improved drivetrain rigidity and reduced wheel hop under hard acceleration. Urethane’s inherent stiffness over rubber translates to more direct power transfer and enhanced handling precision, crucial for maximizing the Cappuccino’s nimble chassis.
Addressing suspension geometry and wear, we’ve secured adjustable upper control arms for both the front and rear of the Cappuccino. These meticulously crafted arms, designed and fabricated in the USA by 1uzta40 on Instagram (the same creator behind a sought-after big brake kit), offer significant advantages. They allow for precise camber adjustments, essential for optimizing tire contact patch during cornering and correcting geometry imbalances, particularly important if the car is lowered. Beyond adjustability, these arms serve as a comprehensive solution to replace common wear points – worn-out bushings, deteriorated boots, and potentially tired ball joints. Considering the labor and cost involved in sourcing individual replacement components and refurbishing the original arms, this upgrade presents a streamlined and cost-effective approach to refreshing and enhancing the suspension system.
For a significant leap in handling performance, a set of lightly-used, high-end coilovers from Yahoo Japan Auctions was acquired. This isn’t just any suspension kit; it’s a Cosmic Garage bespoke Öhlins setup, a rare and discontinued gem originally priced around 400,000 yen. These coilovers, used for a mere 3,000km, represent a substantial upgrade over stock, offering superior road holding and adjustability. Featuring front and rear screw-type vehicle height adjustment and 20-step damping force adjustment, they allow for precise tuning of the Cappuccino’s handling characteristics. The included Swift springs (8k front, 5k rear) are firmer than stock, leaning towards performance without being overly stiff for street use, suitable for spirited driving and even gymkhana or circuit events, as intended by Cosmic Garage. While a premium component for a budget-friendly car, the value proposition becomes clear when considering the cost of replacing worn stock components with new OEM parts.
Finally, to boost the Cappuccino’s power output, a complete, lightly-used Monster Sport K100 kit was sourced. Monster Sport, formerly Suzuki Sport, is Suzuki’s renowned tuning arm, and their K100 kit is designed to elevate the Cappuccino’s horsepower from approximately 64hp to a more exhilarating 100hp. This comprehensive kit includes a plug-and-play ECU, larger injectors, and an upgraded turbocharger engineered to fit within the stock location, simplifying installation. This particular kit is the rarer K100 version, compatible with the alloy-block K6A engine, as opposed to the more common F100 kit for the iron-block F6A. Adding to the appeal, this kit came with an aftermarket tubular exhaust manifold. While the manufacturer is unknown, the manifold appears to be of good quality with a substantial flange. Consideration is being given to ceramic coating the manifold to manage heat, a known issue with this component according to previous owners. The chosen turbo upgrade approach prioritizes ease of installation and reversibility, avoiding the complexities of relocating components and modifying supporting systems often associated with more radical turbo upgrades. An aftermarket blow-off valve was also included, though its suitability for the Cappuccino is under review, as some reports suggest potential lag issues with atmospheric venting in this application. Recirculation might be necessary to maintain optimal performance.
These acquired Suzuki Cappuccino Car Parts represent a significant investment in enhancing the performance and driving experience of this iconic kei roadster. While the installation is not immediate, the anticipation of transforming the Cappuccino with these carefully selected upgrades is already building. Stay tuned for future updates as these parts find their way onto the car and onto the road.
