If you own a B5 Audi A4, S4, or RS4 Quattro, you know the importance of maintaining structural integrity, especially when pushing your vehicle to its limits. The 034Motorsport Billet Aluminum Rear Subframe Reinforcement Kit is engineered specifically for your ride, crafted from T6-6061 Billet Aluminum to deliver unmatched rigidity and durability. This upgrade is essential for preventing the common issue of rear subframe failure, particularly when upgrading to a stiffer rear sway bar.
Before hitting the market, this kit underwent rigorous testing on both the street and the track using our shop's B5 Audi S4. We didn't just design it; we put it through its paces to ensure it meets the demands of performance enthusiasts like you.
If your Audi is lowered, it's crucial to check all clearances throughout the full range of suspension articulation to avoid any potential interference. We recommend pairing this kit with 034Motorsport suspension components, as they are designed to work seamlessly together.
A B5 S4 owner recently installed this kit alongside an upgraded sway bar and reported, “The 034 reinforcement kit gave me peace of mind. I was worried about the rear subframe cracking, but after the install, it feels solid. No more worries during aggressive cornering!”
Upgrade your B5 Audi A4/S4/RS4 with the 034Motorsport Rear Subframe Reinforcement Kit and enjoy enhanced performance without the fear of failure.
