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.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"col-2\"\u003e\n\u003cdiv class=\"col2-set\"\u003e\n\u003cdiv class=\"col-1\"\u003e\n\u003cdiv class=\"std\"\u003e\n\u003ch3\u003eBrake Caliper Design:\u003c\/h3\u003e\n\u003cp\u003eA 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 reduces the overall heat capacity of the braking system as well, resulting in the system overheating quickly under repeated braking events\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eWhen 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ctable cellspacing=\"2px\" class=\"fitmentGuide responsive-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCaliper Design\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003e8-Piston, CNC Machined Monoblock Billet Calipers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLightweight, High-Strength Construction\u003cbr\u003e(Caliper + Bracket + Pads + Hose)\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eFactory B8 S4: 18.1 Lbs\u003c\/li\u003e\n\u003cli\u003eFactory B8 SQ5: 17.5 Lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e034 RS+:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e13.5 Lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncreased Brake Pad Area\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eB8 S4 OE: 8,167 mm2\u003c\/li\u003e\n\u003cli\u003eB8 SQ5: 9,538 mm2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e034 RS+:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e9,943 mm²\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReadily Available Brake Pads\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eBrembo GT6 Caliper Pad Shape\n\u003cul\u003e\n\u003cli\u003e57mm Radial Pad Depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThree Finish Options\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eNickel Plated\u003c\/li\u003e\n\u003cli\u003eRS Red\u003c\/li\u003e\n\u003cli\u003eBlack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cbr\u003e\n\u003ch3\u003e2-Piece Rotor Design:\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ctable class=\"fitmentGuide responsive-table\" cellspacing=\"2px\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLarger Brake Rotors\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eOE: 345x30mm (B8 S4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e034 RS+:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e390x34mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotorsport-Inspired Design\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eFloating, 2-Piece Design\u003c\/li\u003e\n\u003cli\u003eAerospace Grade Aluminum Hats\u003c\/li\u003e\n\u003cli\u003eCM-250 Special Alloy Rotor Rings\u003c\/li\u003e\n\u003cli\u003eJ-slotted Friction Face\u003c\/li\u003e\n\u003cli\u003e72 Curved Vanes Force Cooling Air through Brake Disc\u003c\/li\u003e\n\u003cli\u003eFloating Bobbins Mounting System\u003c\/li\u003e\n\u003cli\u003eReduced Unsprung Weight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEasy Maintenance\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eReplaceable Rotor Rings, Lower Long-term Maintenance Cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLightweight Construction (Caliper + Rotor)\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eOE S4\/S5: 42.2 Lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e034 RS+ (390x34mm):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e38.8 Lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"034 Motorsport","offers":[{"title":"Nickel","offer_id":49843056443585,"sku":"034-301-0008-NKL","price":4494.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":49843056476353,"sku":"034-301-0008-BLK","price":4338.0,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":49843056509121,"sku":"034-301-0008-RED","price":4338.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/034motorsport-rs-big-brake-package-b8-b8-5-audi-a4-s4-rs4-a5-s5-rs5-and-q5-sq5-034-301-0008-001.webp?v=1765487675","url":"https:\/\/www.urotuning.com\/products\/034motorsport-rs-big-brake-package-audi-b8-b8-5-a4-s4-rs4-a5-s5-rs5-q5-sq5-034-301-0008-nkl","provider":"UroTuning","version":"1.0","type":"link"}
