Description

The Grannas Racing T56 Magnum-F 6-speed manual swap kit offers a fully customizable solution for upgrading your MKIV Supra's drivetrain. While the manual tunnel generally requires only minor modifications, such as slight hammer tapping near the reverse lockout and shifter hole, automatic-to-manual conversions will necessitate trimming of the original tunnel. Grannas Racing provides various transmission options, including the popular GR700 (700 ft-lb rated), the GR1200 (1100+ HP recommended with billet components and REM ISF finished gears), and the ATLAS (tested to 2000 ft-lbs with dog engagement on all gears). Clutch choices range from the smooth-engaging Tilton ST246 twin disc (900 ft-lbs) to the high-capacity McLeod RXT 1200 (1000+ ft-lbs), catering to different power levels and driving preferences. This kit emphasizes ease of installation with optional, but recommended, driveshaft and clutch components. Grannas Racing also offers essential auto-to-manual conversion parts like clutch and brake pedals, as well as interior and shift boots. The company stresses its commitment to quality control, thorough testing, and providing complete kits with all necessary hardware to ensure a hassle-free build. Note that all products purchased from Grannas Racing are intended for motorsport purposes only and must not be installed on vehicles driven on public streets or highways unless explicitly stated otherwise.
