The ultimate braking upgrade for your Audi or Volkswagen. The NEUSPEED Version 3 Big Brake Kit transforms your vehicle’s stopping power with a performance-proven 6-piston caliper system and our own NEUSPEED 2-Piece Floating Brake Rotors — engineered for reduced weight, improved cooling, and race-grade durability.
Version 3 introduces refinements designed for enthusiasts who demand more: enhanced caliper scalloping for additional wheel clearance, and new Titanium-Nitride (TiN) coated pistons for reduced friction, greater durability, and superior consistency under extreme heat cycles. The result is a package that delivers exceptional pedal feel, precise modulation, and serious stopping power — on the street or the track.
Factory Audi Braking Limitations
While Audi equips the B9 A4/S4/A5/S5/Q5/SQ5 with capable brakes for daily use, the stock systems have well-known drawbacks under performance driving:
-
Heat Soak and Fade – Factory calipers and one-piece rotors struggle under repeated heavy braking, quickly leading to fade and longer stopping distances.
-
Caliper Expansion – OEM cast calipers expand under heat, softening pedal feel and reducing consistency.
-
Unsprung Weight – Heavy, cast one-piece rotors and bulky calipers dull suspension response and handling precision.
-
Vague Modulation – Stock pedal feel can become inconsistent or spongy during spirited or track driving.
- Limited Upgrade Path – OEM pad and rotor sizing restricts performance compound options and aftermarket support.
The NEUSPEED BBK was designed specifically to solve these issues.
Key Upgrades in Version 3
- NEUSPEED 2-Piece Floating Brake Rotors are now included standard
- Additional scalloping to caliper body for improved wheel clearance
- New titanium-nitride-coated pistons with naturally ultra-low-friction properties, replacing bare, uncoated stainless steel pistons
Features
CNC Machined & Forged Aluminum Caliper Body
Each caliper is precision CNC-machined from forged 6061-T6 aluminum, optimizing strength and reducing weight. Forging realigns the aluminum’s grain structure for unmatched rigidity—far superior to cast or billet alternatives.
Titanium-Nitride (TiN) Coated Low-Friction Pistons
Version 3 features a leap in durability and heat resistance with our new hard-coated titanium-nitride (TiN) pistons. These high-performance components reduce friction, resist corrosion, and deliver consistent feel in extreme heat—making them ideal for spirited driving or track abuse.
NEUSPEED 2-Piece Floating Rotors (370x34mm)
- Lightweight, internally ventilated design
- Floating hardware prevents warping under thermal expansion
- Directional vane design for maximum airflow and cooling efficiency
- Reduces unsprung weight for sharper handling and improved ride quality
- Direct-fit sizing for VW/Audi applications
(Note: some factory wheels may require a 15mm spacer for clearance — always check our caliper template before ordering.)
Internal Seals System
NEUSPEED Calipers boast a cutting-edge design with dual internal piston seals. The hydraulic seals, crafted from high-temperature-resistant composite material, exhibit remarkable resilience against fatigue from regular daily use and endure the rigors of high-temperature competition scenarios. Reinforcing the system's durability, the second seal, also composed of the same material, provides a protective barrier against external contaminants like dust and moisture. This innovative 'Internal Dust Seal' system stands as a superior alternative to the conventional external shield/boot system, ensuring unmatched durability and performance.
Calipers Matched to VW/Audi Master Cylinders
NEUSPEED, as a dedicated VW/Audi tuning company, takes precision to a new level with calipers meticulously engineered to seamlessly pair with VAG factory master cylinders. In stark contrast to other brake manufacturers, we refrain from a one-size-fits-all approach by carefully selecting and tuning our 6-piston calipers to cater specifically to each VW and Audi model. This attention to detail prevents the issues associated with mismatched caliper sizes, such as a spongy or overly sensitive pedal feel. Our commitment to precision ensures optimal pedal modulation, allowing for precise and responsive braking points—a crucial element in elevating your driving experience.
Quick Pad Change System
The NEUSPEED caliper, crafted by enthusiasts for enthusiasts, prioritizes convenience and efficiency in its design. At the forefront of our engineering considerations is the ability to swiftly and conveniently swap brake pads. Facilitating this seamless process is the removable bridge-pin and pins system, enabling users to swap pads without the need to remove the caliper entirely. With a straightforward procedure involving unbolting the top bridge, undoing the guide pins, and sliding out the pads, the entire operation takes a mere 15 minutes. Experience the ease of maintenance and customization with NEUSPEED – where every detail is designed to enhance the enthusiast experience.
Pad Wear Sensor Compatible (If Equipped)
The NEUSPEED big brake kit seamlessly integrates with the VW/Audi factory sensor kit, eliminating the need for users to splice and bridge the sensor connector to prevent error lights on the dashboard. This ensures a genuine OEM replacement experience.
Aerospace Grade Mounting Bracket
Crafted from steel metal, this component features a protective black epoxy coating designed to safeguard against corrosion and degradation.
High-Quality Hardware
Each NEUSPEED Brake Kit encompasses stainless steel braided PTFE core brake lines, accompanied by stainless steel fittings. The kit is further complemented with stainless steel bleeder valves, guide pins, connecting tube, and robust 12.9-grade mounting bolts for a comprehensive and high-performance braking solution.
