Show original supplier description

The KMiata KM-K-ZF5-KIT-GETRAG-BLK package facilitates the installation of a BMW ZF 5-speed transmission into K-series-powered Mazda Miata models (NA and NB). The package features a CNC-machined steel, zinc-plated adapter plate, a 6061 aluminum flywheel with a replaceable friction surface designed to accept an OEM E46 clutch kit, and a custom extended release bearing. Key components also include a stainless steel short shifter with ball bearings for improved action, an aluminum selector rod with a dual-shear design to prevent slop, and a billet aluminum shifter plate. A new 3.5-inch aluminum driveshaft with larger diameter splines is included for consistent power delivery and vibration-free operation, tested to over 150 mph. The kit also contains a tunnel-mounted steel transmission mount, upgraded bushings, a 3/4-inch Wilwood clutch master cylinder with braided stainless line, and a Sachs E36 clutch slave cylinder. All parts are proudly made in the USA. Installation requires an E46 clutch kit specifically for a 330i 5-speed car (10 spline, 240mm clutch disc) that includes a pressure plate designed for an OEM E46 flywheel. A Honda flywheel bolt (90011-RDB-000) is also required. Supporting products recommended for optimal setup include a Miata Differential Mount for PPF Delete, an ACT HD or Spec Stage 1/3+ clutch kit, and a Haltech GPS Speed Sensor if retaining a working speedometer with a Haltech ECU is desired.
