034Motorsport is proud to offer the ultimate rear subframe reinforcement solution for the B5 Audi A4/S4/RS4 Quattro! The 034Motorsport Billet Aluminum Rear Subframe Reinforcement Kit is made from T6-6061 Billet Aluminum for maximum rigidity and is designed to prevent failure of the rear subframe on B4/B5 Quattro vehicles, which is very common with upgraded rear sway bars.

Kit Includes:

• 034Motorsport B5 Audi A4/S4/RS4 Quattro Rear Subframe Reinforcement Kit
• High-Grade Installation Hardware

Please Note: This rear subframe reinforcement bracket is required when using an upgraded sway bar on B4/B5 chassis Quattro vehicles. The rear subframe is prone to cracking with an upgraded sway bar, and will likely crack if you attempt to use this sway bar without subframe reinforcements. If you do not already have a subframe reinforcement kit, you must purchase the 034Motorsport Billet Rear Subframe Reinforcement Bracket. This subframe reinforcement kit fits Quattro vehicles only.

Also, Note: Your subframe will not line up fully with this kit, as the stock brackets have moved around over time. This is a known issue with the factory brackets, as they are not reinforced properly. When you install this kit and tighten everything down, it will pull it back into position.
