Product Information
The 034Motorsport RS+ Big Brake Package for the B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, & Q5/SQ5 is engineered to deliver unparalleled braking performance, whether on the street or the track. This comprehensive package was engineered to offer superior stopping power, enhanced brake modulation, and long-term durability, making it the ideal choice for enthusiasts who demand the best from their braking system.
Brake Caliper Design:
A major weakness of the factory single-piston floating caliper utilized on the B8/B8.5 S4 models is its tendency to heat soak after just a few repeated braking events, leading to brake fade and poor braking performance during high-performance use, particularly on track days. The undersized nature of the OEM brake caliper and rotor significantly reducesthe overall heat capacity of the braking system as well, resulting in the system overheating quickly under repeated braking events
The RS+ Big Brake Package utilizes a durable yet lightweight, CNC-machined 8-piston billet brake caliper. This design provides superior structural integrity, enhancing braking precision and pedal feel. The open design allows for improved heat dissipation, allowing the RS+ Brake Calipers to manage higher temperatures better, ensuring consistent performance and minimizing the risk of brake fade during extended track use.
When designing a Big Brake Kit, there's a common misconception that larger brakes inherently produce more stopping power. With an improperly designed larger brake caliper for the car it is being installed upon, more bias is shifted towards the front, which is not ideal for a vehicle that already has a front-heavy brake bias. The factory B8/B8.5 S4 calipers generate more than enough brake force to engage ABS, which is the limit of braking maximum, but lack the ability to better balance this force across all 4 wheels repeatedly as heat is generated. For these reasons, 034Motorsport engineers sought specifically to improve brake balance, increase heat capacity, and improve heat transfer of the front brakes to allow for better high-load braking performance for a significantly longer period of time.
The RS+ Big Brake Package was engineered with a 4% smaller piston area in comparison to the factory S4/S5 brakes to strategically shift more braking force to the rear brakes. This improved redistribution of braking load keeps the car more flat during threshold braking (braking as hard as possible without engaging ABS), reducing front-end dive, and better redistributes braking force to all 4 corners, versus overloading just the front two. This optimized balance allows for better control, allowing for sharp turn-in response, more rotation in trail braking, and giving drivers greater confidence and precision when navigating corners, particularly in high-performance driving scenarios on the track.
2-Piece Rotor Design:
The RS+ Big Brake Package includes larger, Floating 2-Piece 390x34mm Brake Rotors. By increasing the rotor size to a massive 390mm, the RS+ Big Brake Package enhances performance by increasing the overall surface area and heat dissipation capacity. The larger rotor increases the lever arm on the brakes which improves braking force, improves stopping power and responsiveness, and gives drivers more control and confidence, especially during high-speed, heavy braking.
The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed from a proprietary metal alloy that can withstand immense braking temperatures while holding form.
The 034Motorsport 2-Piece Floating Brake Rotors utilize 72 directionally curved vanes properly oriented for each side of the vehicle to forcefully flow cool air through both rotors to dissipate heat equally. The larger 390mm rotor diameter allows for enhanced cooling under high-heat conditions, such as track use or aggressive driving to help prevent brake fade. By managing heat more efficiently, these rotors maintain consistent braking performance during extended periods of intense use, ensuring the driver has more control and confidence when pushing their braking system to its limits.
The face of the 034Motorsport 2-Piece Floating Brake Rotors utilize J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.
The 034Motorsport rotor and hat floating mount system utilize high-strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.
Brake Line Design:
The RS+ Brake Package uses Teflon-lined stainless steel braided brake lines and a protective black PVC covering. Unlike the stock rubber hose, this stainless steel braided hose will not bulge or expand with brake pressure, resulting in an improved pedal feel and more consistent braking performance.
StreetSport Brake Pad Design:
The RS+ Big Brake Package includes 034Motorsport’s StreetSport Brake Pads, designed for street and light-level track use. These semi-metallic pads offer low brake dust and noise, making them ideal for daily driving, all while providing the high coefficient of friction, initial bite, and heat resistance necessary for track driving.
The StreetSport Brake Pads maintain excellent modulation and consistent linear control across a wide temperature range, performing consistently up to 1112°F (600°C). Their balance of performance and versatility make them a great choice for occasional track use without the downsides of dedicated track pads.
034Motorsport TrackSport Brake Pads are in production and will be available in the coming months.
Optional Extra: 034Motorsport Titanium Brake Shims for RS+ Big Brake Package:
For those that use their brakes to the maximum either on the road, and especially those that take their car to the track, 034Motorsport engineers developed an additional heat-blocking upgrade in the form of Titanium Brake Pad Shims for the RS+ Big Brake Package. Positioned between the brake pad and caliper, titanium shims’ low thermal conductivity reduces heat transfer, preventing brake fluid overheating and brake fade during intense track use. This upgrade enhances safety and brake modulation while extending the lifespan of components like caliper seals, lowering long-term maintenance costs. Additionally, titanium shims help minimize brake squeal, providing quiet and reliable performance. We highly recommend adding this option during checkout if you are looking to get the most performance out of your braking system.
