RH9

Club RH9 is a group of tuning shops across Japan, from Hokkaido to Kyushu, set up in October 2003 with its head office in Sakai, Fukui Prefecture. Club RH9 began with pro shops competing to run the Skyline GT-R down the quarter mile in nine seconds, and the name comes from "Record Holder".

Club RH9 develops and sells its own parts and engine computer settings for the Nissan GT-R R35, the RB-engined Skyline GT-R, the Toyota 86 and Subaru BRZ, and a titanium exhaust for the GR Supra. Club RH9 also buys parts together for its member shops and runs a yearly track day at Suzuka Circuit.
