FactionFab V2 Performance Brake Pads
FactionFab V2 Brake Pads use a semi-metallic performance compound engineered to provide consistent braking power, predictable modulation, and effective heat management. The Stage 1 compound is designed for daily driving, aggressive street use, autocross, and light track applications.
The semi-metallic formulation efficiently dissipates heat during repeated braking while maintaining dependable low-temperature performance for everyday use. With an average coefficient of friction of approximately 0.39µ and up to 0.44µ at cold temperatures, the pads provide responsive braking characteristics across a broad operating range.
Brake Pad Features:
- Semi-metallic friction compound
- Designed for aggressive street driving, autocross, and light track use
- Stage 1 performance compound
- Approximately 0.39µ average coefficient of friction
- Up to 0.44µ coefficient at cold temperatures
- Strong low-temperature braking performance

- Predictable thermal behavior under demanding conditions
- Textured steel shims for improved heat dissipation and grease retention
- OE-spec backing plates for precise fitment
- Gas slots and chamfers to help reduce vibration and noise
- Laser-cut backing plates for durability and noise reduction
- Applicable installation hardware included
FactionFab V2 High-Carbon Slotted Brake Rotors
FactionFab V2 Rear Brake Rotors are manufactured from G11H18 high-carbon iron alloy to provide excellent heat dissipation, durability, and consistent braking performance. The precision-machined F-design slots help evacuate brake dust and gases from the friction surface, supporting consistent pad contact during repeated braking.
The rotors are double-disc ground for accurate thickness and surface finish and are mill balanced to help minimize vibration. A full Geomet zinc coating is applied to the interior and exterior surfaces to improve corrosion resistance and maintain the rotor's appearance.
These rotors feature a 316mm diameter and are dual-drilled for 5x100 and 5x114 applications, depending on the specific application. Threaded M8 removal holes make rotor removal easier during maintenance and servicing.

- Part number and minimum thickness stamped on rotor edge
- Bi-directional design for left- or right-side installation
- Double-disc ground for precise thickness and surface finish
- Mill balanced for smooth, vibration-free operation
FactionFab Stainless Steel Rear Brake Lines
The included FactionFab Stainless Steel Brake Lines replace the factory rubber brake lines with a model-specific stainless steel design. Factory rubber lines can flex, swell, and deform under pressure and temperature, which can contribute to a softer or less precise pedal feel.
The FactionFab stainless steel lines use a PTFE Teflon inner liner, stainless steel woven reinforcement, and an abrasion-resistant outer coating. This construction is designed to provide increased durability while delivering more direct brake-pedal feedback and a firmer, more consistent braking response.
Each brake line is 4500 psi burst-pressure tested and engineered specifically for the applicable vehicle to provide proper fitment.
Brake Line Features:
- Model-specific design for proper fitment
- Stainless steel precision-machined fittings
- PTFE Teflon inner liner
- Stainless steel woven reinforcement layer
- Abrasion- and impact-resistant construction
- Clear PCV outer protective coating
- Helps protect against chafing and external damage
- Stress relief at fitting locations
- 4500 psi burst-pressure tested
- Increased pedal feedback compared with factory rubber lines
- Designed to reduce line expansion and deformation
- Installation hardware included
FactionFab 6AL-4V Titanium Brake Shims
The included FactionFab Titanium Brake Shims are designed to help reduce heat transfer from the brake pads into the caliper pistons during aggressive driving, autocross, and track use.
Repeated heavy braking generates substantial heat, and excessive heat transfer into the caliper can increase brake-fluid temperatures and contribute to brake fade. The titanium shim creates a thermal barrier between the brake pad and caliper piston, helping reduce heat transfer and maintain more consistent brake performance.
Manufactured from 6AL-4V / Grade 5 Titanium, these shims measure 1.0mm thick. Titanium has significantly lower thermal conductivity than steel, making it an effective material for insulating the caliper from brake-pad heat.
The shims can help provide more consistent braking during extended track sessions while potentially reducing heat-related brake fade and extending brake-pad life.
Titanium Shim Features:
- 4 shims included
- Manufactured from 6AL-4V / Grade 5 Titanium
- 1.0mm thickness
- Lower thermal conductivity than steel
- Creates a thermal barrier between the brake pad and caliper piston
- Helps reduce heat transfer into the caliper and brake fluid
- Helps reduce the risk of heat-related brake fade
- Can help extend brake-pad life during demanding use
- Suitable for performance driving, autocross, and track applications
- May qualify for certain SCCA and NASA classes; always verify current official class rules before competition
