Flat tow your Mini Cooper S behind your motorhome with clean styling and maximum structural strength using the authentic Roadmaster 521886-5 Direct-Connect Baseplate Kit (also cataloged by retailers as RM54MR). Engineered specifically for late-model Mini Cooper S applications (including 2022–2024 manual transmission models), this direct-connect baseplate integrates seamlessly into the vehicle chassis and lower grille area.

Roadmaster Direct-Connect baseplates eliminate the need for a separate quick-disconnect crossbar—allowing motorhome-mounted Roadmaster tow bars (such as the Nighthawk, Sterling, Falcon All-Terrain, or Blackhawk) to pin directly into the mounting brackets. When not actively towing, simply twist and remove the front extension arms with the built-in quick-release pull rings to restore your Mini Cooper's factory styling and protect your shins.

Key Features & Engineering Highlights:

  • Direct-Connect Streamlined Design: Connects directly to compatible Roadmaster tow bars without requiring a heavy crossbar across the front bumper.
  • Removable Arms: Easy twist-lock arms click firmly into place for towing and disconnect in seconds for everyday driving.
  • Computer-Tested Structural Integrity: Subjected to extensive Finite Element Analysis (FEA) computer testing to withstand extreme dynamic towing loads and road shock.
  • Clean OEM Appearance: Custom engineered to fit existing chassis mounting points behind the front fascia with minimal exterior trimming and zero welding required.
  • Durable Protective Finish: Coated in heavy-duty baked-on black powder coat to resist chipping, gravel impact, road salt, and harsh weather.
  • Professional Installation & Upfitting: Expert flat-tow rigging, baseplate installation, diode wiring, and braking system setup available at Truck Guy Upfitters (510 W North 1st St, Seneca, SC 29678).
