All About Fiberglass – Commonly Used Aero for Kaido Racers

If you are planning on building a kaido racer, chances are you will probably need some sort of fiberglass parts to complete the look. Even simple cars can benefit from smaller fiberglass goodies like an ita panel or chin spoiler. More extreme builds will use multiple different types in creative ways.

Early kaido racers typically just had works over fenders. When the big aero boom happened in the mid to late ’80 everyone was using aero. Specific aero was popular in certain areas of Japan along with at different points in time. Many of these examples are from an early 1990s Champ Road yearbook magazine.

Some of these fiberglass parts are now made for sale in the USA by Moonlight Runners.

Slit Spoiler
スリットスポイラー

Originally made by FET, the slit spoiler is NOT an upside down wing. As shown in the catalogue photos below this was produced with the intent of being mounted under the rear bumper. Like many of these other fiberglass parts, other companies would produce similar ones or remake them without permission. These are still readily available in different shapes and sizes, but no longer produced by FET.

Mazda RX-7 IMSA panel “seven panel”

In 1978, Jim Hagerty and Dan Mccue teamed up to create “Design Energy”, a company focused on making various products using injection molding. Rotary Engineering of Santa Barbra, CA approached them in 1980 to develop a wide body kit, along with this seven panel, for the brand new Mazda RX-7. Their company would then sell them under the name “Mariah Motorsports.” These body kits were then used in the IMSA GT races under the GTO (Grand Touring Over 2.5l) and GTU (Grand Touring Under 2.5l) divisions. This part was also popular to extend out, with some examples adding up to 60cm to the overall length.

Airone Gate
アイローネ ゲート

The airone gate turns cars like the S30 into something resembling a mid-engine car like a Ferrari with this replaceable hatch. In western culture this is sometimes refered to as a “Pantera hatch.” The first company to mass produce them was Takama Competition Products and sold it under their Checkman “チェックマン” brand sometime in the late 1970s. Yamato also made a similar style gate. It was popular with cars like the S30 and S130 Fairlady Z, Savanna RX-7, and Celica XX.

Nissan Skyline Hakosuka “Itapane / 板ッパネ”

This wing is a popular addition to hakosuka works cars in the 1970s. It is so common on these cars it almost seems like a factory part. Itapane is a nickname for this wing meaning “board panel.”
