Competition Clutch flywheels are made of 4140 forged chromoly steel, and are a one-piece design. This helps significantly in reducing the chances of ring gear separation and friction surface warpage. All flywheels can be resurfaced.
Flywheel weight for these applications is 10.5 lbs + counterweight.
These flywheels are SFI approved to meet competition safety requirements.
Koyo all aluminum racing radiators for 1983-1985 FB RX-7 (12A and 13B models), 1986-1991 FC RX-7 (Turbo II and Non-Turbo models), and 1993-2002 FD RX-7.
With over 50 years of experience in the manufacturing of OE replacement radiators, it was only natural that Koyo develop a lightweight, high performance radiator line. We are proud to offer their all aluminum performance radiators designed as a true drop in installation for select vehicles, utilizing the factory equipped fan shrouds without any modifications necessary.
PLEASE NOTE: These radiators are designed specifically for Manual Transmission vehicles only. If installing one of these radiators into an Automatic vehicle, a separate transmission cooler MUST be installed.
