Prius and Subaru BRZ, which comply with JAF-GT regulations. However, the GT300 class is predominantly composed of GT3-class cars from European manufacturers such as Audi and Mercedes, although Lexus, Nissan and Honda are also represented in the class by GT3 cars. This reflects a growing interest in the series from European manufacturers, with Audi and BMW fielding works-supported entries. Lexus, Nissan, and Subaru also campaign works-supported cars in the class. The GT300 class used to host more exotic cars from the likes of ASL, Mosler, Mooncraft, and Vemac (a Lotus tuner), as well as detuned GT500 cars, such as the 2004 title-winning M-TEC NSX. However, starting in 2006, teams increasingly chose to campaign European GT cars instead, a trend that accelerated in 2010 with the introduction of FIA GT cars to the series. In response to the decline of locally produced entries from specialist manufacturers, the GTA worked with Dome to create the "Mother Chassis" (:ja: マザーシャシー), a low-cost GT300 platform, with the first MC car entering the series in 2014. Mother Chassis cars utilize a standard Dome-produced tub and GTA-branded Nissan VK45DE engine, while maintaining the appearance of production cars such as the Toyota 86, Lotus Evora, and Toyota Mark X. The MC concept proved to be popular with independent teams, as well as competitive, with the Toyota 86 MC winning the GT300 championship in 2016. Since 2006, Group GT1 and Group GT2 could race in GT300, and Group GT3 cars are able to enter GT300 since 2010 season. After the 2011 season, GTA announced GT1 and GTE cars are not eligible anymore with the intention of reducing costs, and adopted full GT3 rule. One of the more unique GT300 competitors was the Mooncraft Shiden MC/RT-16, a Riley Daytona Prototype-based revival of the original 1977 Mooncraft Shiden 77 (紫電77). It competed from 2006 to 2012, narrowly losing the title in 2006, and winning the championship in 2007. Front-wheel drive cars such as the Mitsubishi FTO, Toyota Celica and Cavalier, a rarity in top-level circuit racing, are further examples of unique GT300 machines. They competed in their original configurations until the early 2000s, when FWD cars were being permitted to be converted to rear-wheel drive configuration. The FWD cars were mostly unsuccessful, failing to win any championships, although a Celica won a race in 1999 after a Porsche 911 was disqualified. Rear-wheel drive cars dominated the series until 2008, when
