As one of the foremost tuners of rotary engines, RE Amemiya, has a solid reputation for taking Mazda's cars and making them into exotic-devouring supercars. The company entered the All-Japan Grand Touring Car Championship (JGTC) with an FD3S RX-7 in 1995, waging war in the GT300 class, against many factory teams, but RE Amemiya proved to be a giant-killer, as it consistently placed at the top of the pack.
