If you're looking to take your Audi's handling to the next level, let me tell you about the APR Strut Tower Brace for the B9 chassis models. This piece isn’t just another shiny accessory for your engine bay; it’s a serious upgrade that really makes a difference in how your car feels on the road. It fits a range of models including the A4 from 2017 to 2025, S4 from 2018 to 2025, RS4, A5 from 2017 to 2025, S5 from 2018 to 2024, and RS5 from 2018 to 2025.

What sets this brace apart is its construction. The factory aluminum brace is decent, but the APR brace swaps that out for a high-strength tubular chromium-molybdenum alloy steel design. This change not only ramps up the structural support but also keeps your ride comfortable. You’ll notice less flex when you’re pushing your car through corners, which means you get a more connected driving experience. And let’s be real—who doesn’t want that feeling of being one with their car?

The design features a cross-brace that ties both strut towers together, and there's an integrated turnbuckle for fine-tuning the preload. This means you can adjust the stiffness of the chassis to match your driving style or the conditions, whether you’re cruising on the highway or tackling some twisty back roads. Plus, it’s designed to keep noise, vibration, and harshness (NVH) at bay, so you won’t be sacrificing comfort for performance.

Installation is a breeze, too. It’s a direct bolt-on system, so you won’t need to cut or permanently modify anything. Just grab your tools and get to work—everything you need is included. The black powder-coated finish not only looks good but also protects against corrosion, ensuring that this brace will last as long as your Audi does.
