Competition Clutch Ultra Light Flywheel for 1983-91 RX-7 NA - 2-604-STU

Ultra Lightweight Steel (STU) | 1983-91 RX-7 NA

Give a compatible non-turbo rotary manual setup a more responsive feel with the Competition Clutch 2-604-STU Ultra Lightweight Steel Flywheel. Intended for matching 1.3L RX-7 applications, this STU design is machined with less material to reduce rotational inertia so the engine can change speed more readily during acceleration and rev matching. It is a focused performance option for track, rally, or a modified street build where response is a priority. One-piece 4140 forged steel construction provides an integrated ring gear and durable steel friction surface. Verify the exact rotary engine and clutch arrangement before ordering because turbo configurations and 1.1L 12A engines are outside this listing's scope.
