Product Details
The VTT F3X Ultimate Rear Drag Brake Conversion Kit is the first of its kind designed specifically for the BMW F3X platform to allow the fitment of 15-inch wheels and tires for dedicated drag racing. This kit replaces the bulky, heavy factory single-piston rear calipers and large rotors with a lightweight, high-performance system centered around 4-piston Wilwood calipers. By downsizing the rotor diameter and utilizing slim-profile calipers, it provides the necessary clearance for popular drag wheels like the Weld RTS 15x10, enabling the use of high-traction slicks or drag radials.
In addition to wheel clearance, this conversion serves as a major weight reduction upgrade, shedding approximately 18 to 20 lbs of unsprung weight from the rear of the vehicle. This reduction in mass improves suspension response and overall acceleration by decreasing the energy required to rotate the assembly. While optimized for the strip, this "Plain" rotor version uses high-quality Centric 125 Series blanks, offering a robust and cost-effective solution for racers who prioritize function and weight savings over the aesthetics of drilled or slotted patterns.
Key Features
15-Inch Wheel Compatibility: Specifically engineered to clear 15" wheels, a necessity for serious drag racing setups.
Massive Weight Savings: Reduces unsprung and rotating weight by up to 20 lbs compared to the factory steel brake setup.
4-Piston Performance: Upgrades from a single-piston sliding caliper to a rigid, 4-piston Wilwood Dyna-lite or Dyna-Pro caliper for consistent clamping.
Customizable Brake Compound: This configuration allows you to source your own pads, letting you choose the exact friction material for your racing needs.
Silver Aesthetic: Features sleek silver-finished calipers for a clean, professional look behind your race wheels.
