Product Details

2X Entries Into Our F80 M3 Sweepstakes

The Vargas F3X Ultimate Rear Drag Brake Conversion Kit is a specialized performance upgrade designed specifically for the BMW F3X platform. It addresses a key limitation for drag racers: the ability to fit 15" wheels and slicks over the factory rear brakes. By swapping out the bulky OEM single-piston calipers for lightweight, race-inspired 4-piston Wilwood units, this kit significantly reduces unsprung and rotating weight while maintaining the stopping power needed for high-speed runs.

Key Features

  • 15" Wheel Compatibility: Engineered specifically to allow the fitment of 15" wheels and slicks, which is the first and only kit of its kind for the F3X platform.

  • Significant Weight Reduction: Drops up to 20 lbs of unsprung weight from the rear of the vehicle compared to the stock steel setup.

  • Enhanced Stopping Power: Replaces factory single-piston calipers with high-performance Wilwood 4-piston calipers (Dyna-lite or Dyna-Pro).

  • Durable Rotor Design: Uses Centric 125 Series plain rotors, which are ideal for consistent thermal performance without the risk of cracking often associated with drilled rotors in heavy-use environments.

Specifications

  • Caliper Type: Wilwood 4-Piston (Red finish)

  • Rotor Type: Centric 125 Series Plain

  • Weight Savings: Approximately 18.2–18.7 lbs total (factory brakes: 56 lbs vs. VTT plain kit: ~37.3 lbs)

  • Caliper Weight: ~4.0–4.5 lbs each (vs. factory 11.5 lbs)

  • Rotor Weight: ~14.4 lbs each (vs. factory 18.2 lbs)

  • Included Hardware: CNC-machined brackets, bolts, and adapter fittings
