Product Description

The NRG ST-009CF/MB is a 320mm flat bottom D-shape steering wheel from NRG's Tru-Carbon Fiber series, finished in a matte black carbon fiber that sets it apart from the gloss ST-009CF/BK variant. The matte finish provides the same authentic full carbon fiber construction and ultra-lightweight properties while delivering a more understated, stealth look preferred in modern track and time-attack builds. The flat bottom D-shape mirrors Formula 1 cockpit ergonomics, increasing knee clearance and making entry and exit easier in low-clearance race seat setups.

The 320mm diameter delivers a shorter throw and more responsive feel than larger OEM wheels, and the 3-spoke layout keeps forward sightlines open. The 6x70mm bolt pattern is compatible with NRG quick releases and standard 6-bolt hub adapters. A vehicle-specific short hub adapter is required and sold separately. No horn button is included; horn functionality requires a compatible quick release with horn wire routing. Intended for off-road and competition use only.
