Description
The 034Motorsport RS+ Big Brake Package is engineered for drivers who demand consistent, fade-free braking under aggressive street driving and track conditions. Designed specifically for the B8 and B8.5 Audi platform, this system delivers a major upgrade in stopping power, heat capacity, and brake balance without compromising drivability.
Factory B8/B8.5 braking systems are limited by undersized single-piston floating calipers that quickly heat soak under repeated braking. The RS+ system eliminates this weakness by increasing thermal mass, improving cooling efficiency, and optimizing front-to-rear brake bias.
8-Piston Billet Brake Calipers
The RS+ Big Brake Package features 034Motorsport CNC-machined 8-piston billet aluminum calipers, designed to deliver precise pedal feel and consistent braking performance.
- Lightweight, high-strength billet aluminum construction
- Open caliper design for improved airflow and heat dissipation
- Superior structural rigidity for improved modulation and pedal feedback
- Reduced heat soak compared to factory calipers
To maintain proper brake balance, 034Motorsport engineered the calipers with a 4% smaller piston area than factory S4/S5 brakes. This design shifts braking load rearward, reducing front-end dive and improving overall vehicle stability.
Benefits of optimized brake bias:
- Flatter chassis under threshold braking
- Improved turn-in response
- Enhanced trail braking control
- Increased driver confidence at the limit
390mm Two-Piece Floating Rotors
The RS+ system includes massive 390mm x 34mm two-piece floating brake rotors, significantly increasing heat capacity and braking leverage.
- 390mm diameter increases braking torque and stopping power
- 6061-T6 aircraft-grade aluminum rotor hats
- Proprietary high-temperature rotor alloy for extreme durability
- 72 directionally curved internal vanes for maximum cooling efficiency
- J-slot rotor faces for pad cleaning and reduced braking noise
- High-strength alloy steel bobbins allow safe thermal expansion
These rotors are engineered to maintain consistent performance during repeated high-speed braking and extended track sessions.
Stainless Steel Braided Brake Lines
Included 034Motorsport stainless steel braided brake lines improve pedal feel and braking consistency.
- Teflon-lined stainless steel construction
- Black PVC protective outer coating
- Eliminates rubber hose expansion under pressure
- Firmer pedal feel and improved modulation
034Motorsport StreetSport Brake Pads
The RS+ Big Brake Package includes 034Motorsport StreetSport Brake Pads, ideal for street use with light track capability.
- Semi-metallic compound
- Low dust and low noise characteristics
- High initial bite and strong friction coefficient
- Consistent modulation across a wide temperature range
- Effective up to 1112°F (600°C)
These pads provide excellent everyday comfort without sacrificing performance during spirited driving.
Optional Upgrade – Titanium Brake Pad Shims (Sold Separately)
For maximum thermal protection, 034Motorsport Titanium Brake Pad Shims are available as an optional upgrade.
- Reduces heat transfer from pads to calipers
- Helps prevent brake fluid overheating
- Improves pedal consistency during track use
- Reduces brake squeal
- Extends caliper seal life
Highly recommended for frequent track driving or aggressive braking use.
Important Notes
- Some caliper paint discoloration may occur under repeated high-heat braking
- Type III hard anodizing is a functional coating; minor color variation between batches is normal
