The ACT XACT Streetlite flywheel for 1987 Mazda RX-7 reduces rotational mass compared with stock units while retaining durability for street or drag use. Materials are distributed for strength, lower inertia, heat tolerance and rigidity; the Streetlite is serviceable and resurfacing-compatible, making it a practical, lighter-weight replacement for drivers seeking quicker engine response.
